2. Installing and Upgrading

The FreeNAS® operating system has to be installed on a separate device from the drives which hold the storage data. With only one disk drive, the FreeNAS® web interface is available, but there is no place to store any data. And storing data is, after all, the whole point of a NAS system. Home users experimenting with FreeNAS® can install FreeNAS® on an inexpensive USB stick and use the computer disks for storage.

This section describes:

2.1. Getting FreeNAS®

The latest STABLE version of FreeNAS® 11.2 is available for download from https://download.freenas.org/11.2/STABLE/latest/.

Note

FreeNAS® requires 64-bit hardware.

The download page contains an .iso file. This is a bootable installer that can be written to a USB stick or CD as described in Preparing the Media.

The .iso file has an associated sha256.txt file which is used to verify the integrity of the downloaded file. The command to verify the checksum varies by operating system:

  • on a BSD system use the command sha256 name_of_file
  • on a Linux system use the command sha256sum name_of_file
  • on a Mac system use the command shasum -a 256 name_of_file
  • Windows or Mac users can install additional utilities like HashCalc or HashTab.

The value produced by running the command must match the value shown in the sha256.txt file. Checksum values that do not match indicate a corrupted installer file that should not be used.

2.2. Preparing the Media

The FreeNAS® installer can run from USB stick or a CD.

A CD burning utility is needed to write the .iso file to a CD.

The .iso file can be written directly to a USB stick. The method used to write the file depends on the operating system. Examples for several common operating systems are shown below.

Note

To install from a USB stick to another USB stick, two USB ports are needed, each with an inserted USB device. One USB stick contains the installer. The other USB stick is the destination for the FreeNAS® installation. Take care to select the correct USB device for the FreeNAS® installation. It is not possible to install FreeNAS® onto the same USB stick containing the installer. After installation, remove the installer USB stick. It might also be necessary to adjust the BIOS configuration to boot from the new FreeNAS® USB stick.

Ensure the operating system device order in the BIOS is set to boot from the device containing the FreeNAS® installer media, then boot the system to start the installation.

2.2.1. On FreeBSD or Linux

On a FreeBSD or Linux system, the dd command is used to write the .iso file to an inserted USB stick.

Warning

The dd command is very powerful and can destroy any existing data on the specified device. Make absolutely sure of the device name to write to and do not mistype the device name when using dd! This command can be avoided by writing the .iso file to a CD instead.

This example demonstrates writing the image to the first USB device connected to a FreeBSD system. This first device usually reports as /dev/da0. Replace FreeNAS-RELEASE.iso with the filename of the downloaded FreeNAS® ISO file. Replace /dev/da0 with the device name of the device to write.

dd if=FreeNAS-RELEASE.iso of=/dev/da0 bs=64k
6117+0 records in
6117+0 records out
400883712 bytes transferred in 88.706398 secs (4519220 bytes/sec)

When using the dd command:

  • if= refers to the input file, or the name of the file to write to the device.
  • of= refers to the output file; in this case, the device name of the flash card or removable USB stick. Note that USB device numbers are dynamic, and the target device might be da1 or da2 or another name depending on which devices are attached. Before attaching the target USB stick, use ls /dev/da*. Then attach the target USB stick, wait ten seconds, and run ls /dev/da* again to see the new device name and number of the target USB stick. On Linux, use /dev/sdX, where X refers to the letter of the USB device.
  • bs= refers to the block size, the amount of data to write at a time. The larger 64K block size shown here helps speed up writes to the USB stick.

2.2.2. On Windows

Image Writer and Rufus can be used for writing images to USB sticks on Windows.

2.2.3. On macOS

Insert the USB stick. In Finder, go to Applications ➞ Utilities ➞ Disk Utility. Unmount any mounted partitions on the USB stick. Check that the USB stick has only one partition, or partition table errors will be shown on boot. If needed, use Disk Utility to set up one partition on the USB stick. Selecting Free space when creating the partition works fine.

Determine the device name of the inserted USB stick. From TERMINAL, navigate to the Desktop, then type this command:

diskutil list
/dev/disk0

#:     TYPE NAME               SIZE            IDENTIFIER
0:     GUID_partition_scheme   *500.1 GB       disk0
1:     EFI                     209.7 MB        disk0s1
2:     Apple_HFS Macintosh HD  499.2 GB        disk0s2
3:     Apple_Boot Recovery HD  650.0 MB        disk0s3

/dev/disk1
#:     TYPE NAME               SIZE            IDENTIFIER
0:     FDisk_partition_scheme  *8.0 GB         disk1
1:     DOS_FAT_32 UNTITLED     8.0 GB          disk1s1

This shows which devices are available to the system. Locate the target USB stick and record the path. To determine the correct path for the USB stick, remove the device, run the command again, and compare the difference. Once sure of the device name, navigate to the Desktop from TERMINAL, unmount the USB stick, and use the dd command to write the image to the USB stick. In this example, the USB stick is /dev/disk1. It is first unmounted. The dd command is used to write the image to the faster “raw” version of the device (note the extra r in /dev/rdisk1).

When running these commands, replace FreeNAS-RELEASE.iso with the name of the FreeNAS® ISO and /dev/rdisk1 with the correct path to the USB stick:

diskutil unmountDisk /dev/disk1
Unmount of all volumes on disk1 was successful

dd if=FreeNAS-RELEASE.iso of=/dev/rdisk1 bs=64k

Note

If the error “Resource busy” is shown when the dd command is run, go to Applications ➞ Utilities ➞ Disk Utility, find the USB stick, and click on its partitions to make sure all of them are unmounted. If a “Permission denied” error is shown, use sudo for elevated rights: sudo dd if=FreeNAS-11.0-RELEASE.iso of=/dev/rdisk1 bs=64k. This will prompt for the password.

The dd command can take some minutes to complete. Wait until the prompt returns and a message is displayed with information about how long it took to write the image to the USB stick.

2.3. Performing the Installation

With the installation media inserted, boot the system from that media.

The FreeNAS® installer boot menu is displayed as is shown in Figure 2.3.1.

_images/installer-boot-menu.png

Fig. 2.3.1 Installer Boot Menu

The FreeNAS® installer automatically boots into the default option after ten seconds. If needed, choose another boot option by pressing the Spacebar to stop the timer and then enter the number of the desired option.

Tip

The Serial Console option is useful on systems which do not have a keyboard or monitor, but are accessed through a serial port, Serial over LAN, or IPMI.

Note

If the installer does not boot, verify that the installation device is listed first in the boot order in the BIOS. When booting from a CD, some motherboards may require connecting the CD device to SATA0 (the first connector) to boot from CD. If the installer stalls during bootup, double-check the SHA256 hash of the .iso file. If the hash does not match, re-download the file. If the hash is correct, burn the CD again at a lower speed or write the file to a different USB stick.

Once the installer has finished booting, the installer menu is displayed as shown in Figure 2.3.2.

_images/installer-install-menu.png

Fig. 2.3.2 Installer Menu

Press Enter to select the default option, 1 Install/Upgrade. The next menu, shown in Figure 2.3.3, lists all available drives. This includes any inserted operating system devices, which have names beginning with da.

Note

A minimum of 8 GiB of RAM is required and the installer will present a warning message if less than 8 GiB is detected.

In this example, the user is performing a test installation using VirtualBox and has created a 16 GiB virtual disk to hold the operating system.

_images/installer-drive.png

Fig. 2.3.3 Selecting the Install Drive

Use the arrow keys to highlight the destination SSD, hard drive, USB stick, or virtual disk. Press the spacebar to select it. To mirror the operating system device, move to the second device and press spacebar to select it also. After making these selections, press Enter. The warning shown in Figure 2.3.4 is displayed, a reminder not to install the operating system on a drive that is meant for storage. Press Enter to continue on to the screen shown in Figure 2.3.6.

_images/installer-drive-warning.png

Fig. 2.3.4 Installation Warning

See the operating system device section to ensure the minimum requirements are met.

The installer recognizes existing installations of previous versions of FreeNAS®. When an existing installation is present, the menu shown in Figure 2.3.5 is displayed. To overwrite an existing installation, use the arrows to move to Fresh Install and press Enter twice to continue to the screen shown in Figure 2.3.6.

_images/installer-upgrade-or-fresh-install.png

Fig. 2.3.5 Performing a Fresh Install

The screen shown in Figure 2.3.6 prompts for the root password which is used to log in to the web interface.

_images/installer-root-password.png

Fig. 2.3.6 Set the Root Password

Setting a password is mandatory and the password cannot be blank. Since this password provides access to the web interface, it needs to be hard to guess. Enter the password, press the down arrow key, and confirm the password. Then press Enter to continue with the installation. Choosing Cancel skips setting a root password during the installation, but the web interface will require setting a root password when logging in for the first time.

Note

For security reasons, the SSH service and root SSH logins are disabled by default. Unless these are set, the only way to access a shell as root is to gain physical access to the console menu or to access the web shell within the web interface. This means that the FreeNAS® system needs to be kept physically secure and that the web interface needs to be behind a properly configured firewall and protected by a secure password.

FreeNAS® can be configured to boot with the standard BIOS boot mechanism or UEFI booting as shown Figure 2.3.7. BIOS booting is recommended for legacy and enterprise hardware. UEFI is used on newer consumer motherboards.

_images/installer-boot-mode.png

Fig. 2.3.7 Choose UEFI or BIOS Booting

Note

Most UEFI systems can also boot in BIOS mode if CSM (Compatibility Support Module) is enabled in the UEFI setup screens.

The message in Figure 2.3.8 is shown after the installation is complete.

_images/installer-complete.png

Fig. 2.3.8 Installation Complete

Press Enter to return to Installer Menu. Highlight 3 Reboot System and press Enter. If booting from CD, remove the CDROM. As the system reboots, make sure that the device where FreeNAS® was installed is listed as the first boot entry in the BIOS so the system will boot from it.

FreeNAS® boots into the Console Setup menu described in Booting after waiting five seconds in the boot menu. Press the Spacebar to stop the timer and use the boot menu.

2.4. Installation Troubleshooting

If the system does not boot into FreeNAS®, there are several things that can be checked to resolve the situation.

Check the system BIOS and see if there is an option to change the USB emulation from CD/DVD/floppy to hard drive. If it still will not boot, check to see if the card/drive is UDMA compliant.

If the system BIOS does not support EFI with BIOS emulation, see if it has an option to boot using legacy BIOS mode.

When the system starts to boot but hangs with this repeated error message:

run_interrupt_driven_hooks: still waiting after 60 seconds for xpt_config

go into the system BIOS and look for an onboard device configuration for a 1394 Controller. If present, disable that device and try booting again.

If the system starts to boot but hangs at a mountroot> prompt, follow the instructions in Workaround/Semi-Fix for Mountroot Issues with 9.3.

If the burned image fails to boot and the image was burned using a Windows system, wipe the USB stick before trying a second burn using a utility such as Active@ KillDisk. Otherwise, the second burn attempt will fail as Windows does not understand the partition which was written from the image file. Be very careful to specify the correct USB stick when using a wipe utility!

2.5. Upgrading

FreeNAS® provides flexibility for keeping the operating system up-to-date:

  1. Upgrades to major releases, for example from version 9.3 to 9.10, can still be performed using either an ISO or the web interface. Unless the Release Notes for the new major release indicate that the current version requires an ISO upgrade, either upgrade method can be used.
  2. Minor releases have been replaced with signed updates. This means that it is not necessary to wait for a minor release to update the system with a system update or newer versions of drivers and features. It is also no longer necessary to manually download an upgrade file and its associated checksum to update the system.
  3. The updater automatically creates a boot environment, making updates a low-risk operation. Boot environments provide the option to return to the previous version of the operating system by rebooting the system and selecting the previous boot environment from the boot menu.

This section describes how to perform an upgrade from an earlier version of FreeNAS® to 11.2. After 11.2 has been installed, use the instructions in Update to keep the system updated.

2.5.1. Caveats

Be aware of these caveats before attempting an upgrade to 11.2:

  • Warning: upgrading the ZFS pool can make it impossible to go back to a previous version. For this reason, the update process does not automatically upgrade the ZFS pool, though the Alert system shows when newer ZFS Feature Flags are available for a pool. Unless a new feature flag is needed, it is safe to leave the pool at the current version and uncheck the alert. If the pool is upgraded, it will not be possible to boot into a previous version that does not support the newer feature flags.
  • Upgrading the firmware of Broadcom SAS HBAs to the latest version is recommended.
  • If upgrading from 9.3.x, read the FAQ: Updating from 9.3 to 9.10 first.
  • Upgrades from FreeNAS® 0.7x are not supported. The system has no way to import configuration settings from 0.7x versions of FreeNAS®. The configuration must be manually recreated. If supported, the FreeNAS® 0.7x pools or disks must be manually imported.
  • Upgrades on 32-bit hardware are not supported. However, if the system is currently running a 32-bit version of FreeNAS® and the hardware supports 64-bit, the system can be upgraded. Any archived reporting graphs will be lost during the upgrade.
  • UFS is not supported. If the data currently resides on one UFS-formatted disk, create a ZFS pool using other disks after the upgrade, then use the instructions in Importing a Disk to moun t the UFS-formatted disk and copy the data to the ZFS pool. With only one disk, back up its data to another system or media before the upgrade, format the disk as ZFS after the upgrade, then restore the backup. If the data currently resides on a UFS RAID of disks, it is not possible to directly import that data to the ZFS pool. Instead, back up the data before the upgrade, create a ZFS pool after the upgrade, then restore the data from the backup.
  • The VMware Tools VMXNET3 drivers are not supported. Configure and use the vmx(4) driver instead.

2.5.2. Initial Preparation

Before upgrading the operating system, perform the following steps:

  1. Back up the FreeNAS® configuration in System ➞ General ➞ Save Config.
  2. If any pools are encrypted, remember to set a passphrase and download a copy of the encryption key and the latest recovery key. After the upgrade is complete, use the instructions in Importing a Pool to import the encrypted pools.
  3. Warn users that the FreeNAS® shares will be unavailable during the upgrade; it is recommended to schedule the upgrade for a time that will least impact users.
  4. Stop all services in Services.

2.5.3. Upgrading Using the ISO

To perform an upgrade using this method, download the .iso to the computer that will be used to prepare the installation media. Burn the downloaded .iso file to a CD or USB stick using the instructions in Preparing the Media.

Insert the prepared media into the system and boot from it. The installer waits ten seconds in the installer boot menu before booting the default option. If needed, press the Spacebar to stop the timer and choose another boot option. After the media finishes booting into the installation menu, press Enter to select the default option of 1 Install/Upgrade. The installer presents a screen showing all available drives.

Warning

All drives are shown, including boot drives and storage drives. Only choose boot drives when upgrading. Choosing the wrong drives to upgrade or install will cause loss of data. If unsure about which drives contain the FreeNAS® operating system, reboot and remove the install media. In the FreeNAS® web interface, use System ➞ Boot to identify the boot drives. More than one drive is shown when a mirror has been used.

Move to the drive where FreeNAS® is installed and press the Spacebar to mark it with a star. If a mirror has been used for the operating system, mark all of the drives where the FreeNAS® operating system is installed. Press Enter when done.

The installer recognizes earlier versions of FreeNAS® installed on the boot drive or drives and presents the message shown in Figure 2.5.1.

_images/installer-upgrade-or-fresh-install.png

Fig. 2.5.1 Upgrading a FreeNAS® Installation

Note

A FreeNAS® system can be upgraded by backing up the existing configuration data, performing a fresh install, then restoring the configuration. Back up the configuration with System ➞ General ➞ Save Config. Choose Fresh Install during the installation. After booting into the new install, restore the previous configuration data with System ➞ General ➞ Upload Config.

To perform an upgrade, press Enter to accept the default of Upgrade Install. Again, the installer will display a reminder that the operating system should be installed on a disk that is not used for storage.

_images/installer-upgrade-method.png

Fig. 2.5.2 Install in New Boot Environment or Format

The updated system can be installed in a new boot environment, or the entire operating system device can be formatted to start fresh. Installing into a new boot environment preserves the old code, allowing a roll-back to previous versions if necessary. Formatting the boot device is usually not necessary but can reclaim space. User data and settings are preserved when installing to a new boot environment and also when formatting the operating system device. Move the highlight to one of the options and press Enter to start the upgrade.

The installer unpacks the new image and displays the menu shown in Figure 2.5.3. The database file that is preserved and migrated contains your FreeNAS® configuration settings.

_images/installer-upgrade-preserved-database.png

Fig. 2.5.3 Preserve and Migrate Settings

Press Enter. FreeNAS® indicates that the upgrade is complete and a reboot is required. Press OK, highlight 3 Reboot System, then press Enter to reboot the system. If the upgrade installer was booted from CD, remove the CD.

During the reboot there can be a conversion of the previous configuration database to the new version of the database. This happens during the “Applying database schema changes” line in the reboot cycle. This conversion can take a long time to finish, sometimes fifteen minutes or more, and can cause the system to reboot again. The system will start normally afterwards. If database errors are shown but the web interface is accessible, go to Settings ➞ General and use the UPLOAD CONFIG button to upload the configuration that was saved before starting the upgrade.

2.5.4. Upgrading From the Web Interface

To perform an upgrade using this method, go to System ➞ Update. See Update for more information on upgrading the system.

The connection is lost temporarily when the update is complete. It returns after the FreeNAS® system reboots into the new version of the operating system. The FreeNAS® system normally receives the same IP address from the DHCP server. Refresh the browser after a moment to see if the system is accessible.

2.5.5. If Something Goes Wrong

If an update fails, an alert is issued and the details are written to /data/update.failed.

To return to a previous version of the operating system, physical or IPMI access to the FreeNAS® console is needed. Reboot the system and watch for the boot menu:

_images/boot-menu.png

Fig. 2.5.4 Boot Menu

FreeNAS® waits five seconds before booting into the default boot environment. Press the Spacebar to stop the automatic boot timer. Press 4 to display the available boot environments and press 3 as needed to scroll through multiple pages.

_images/boot-menu-environments.png

Fig. 2.5.5 Boot Environments

In the example shown in Figure 2.5.5, the first entry in Boot Environments is 11.2-MASTER-201807250900. This is the current version of the operating system, after the update was applied. Since it is the first entry, it is the default selection.

The next entry is Initial-Install. This is the original boot environment created when FreeNAS® was first installed. Since there are no other entries between the initial installation and the first entry, only one update has been applied to this system since its initial installation.

To boot into another version of the operating system, enter the number of the boot environment to set it as Active. Press Backspace to return to the Boot Menu and press Enter to boot into the chosen Active boot environment.

If an operating system device fails and the system no longer boots, don’t panic. The data is still on the disks and there is still a copy of the saved configuration. The system can be recovered with a few steps:

  1. Perform a fresh installation on a new operating system device.
  2. Import the pools in Storage ➞ Auto Import Pool.
  3. Restore the configuration in System ➞ General ➞ Upload Config.

Note

It is not possible to restore a saved configuration that is newer than the installed version. For example, if a reboot into an older version of the operating system is performed, a configuration created in a later version cannot be restored.

2.5.6. Upgrading a ZFS Pool

In FreeNAS®, ZFS pools can be upgraded from the graphical administrative interface.

Before upgrading an existing ZFS pool, be aware of these caveats first:

  • the pool upgrade is a one-way street, meaning that if you change your mind you cannot go back to an earlier ZFS version or downgrade to an earlier version of the software that does not support those ZFS features.
  • before performing any operation that may affect the data on a storage disk, always back up all data first and verify the integrity of the backup. While it is unlikely that the pool upgrade will affect the data, it is always better to be safe than sorry.
  • upgrading a ZFS pool is optional. Do not upgrade the pool if the the possibility of reverting to an earlier version of FreeNAS® or repurposing the disks in another operating system that supports ZFS is desired. It is not necessary to upgrade the pool unless the end user has a specific need for the newer ZFS Feature Flags. If a pool is upgraded to the latest feature flags, it will not be possible to import that pool into another operating system that does not yet support those feature flags.

To perform the ZFS pool upgrade, go to Storage ➞ Pools and click  (Settings) to upgrade. Click the Upgrade Pool button as shown in Figure 2.5.6.

Note

If the Upgrade Pool button does not appear, the pool is already at the latest feature flags and does not need to be upgraded.

_images/storage-pools-upgrade.png

Fig. 2.5.6 Upgrading a Pool

The warning serves as a reminder that a pool upgrade is not reversible. Click OK to proceed with the upgrade.

The upgrade itself only takes a few seconds and is non-disruptive. It is not necessary to stop any sharing services to upgrade the pool. However, it is best to upgrade when the pool is not being heavily used. The upgrade process will suspend I/O for a short period, but is nearly instantaneous on a quiet pool.

2.6. Virtualization

FreeNAS® can be run inside a virtual environment for development, experimentation, and educational purposes. Note that running FreeNAS® in production as a virtual machine is not recommended. When using FreeNAS® within a virtual environment, read this post first as it contains useful guidelines for minimizing the risk of losing data.

To install or run FreeNAS® within a virtual environment, create a virtual machine that meets these minimum requirements:

  • at least 8192 MiB (8 GiB) base memory size
  • a virtual disk at least 8 GiB in size to hold the operating system and boot environments
  • at least one additional virtual disk at least 4 GiB in size to be used as data storage
  • a bridged network adapter

This section demonstrates how to create and access a virtual machine within VirtualBox and VMware ESXi environments.

2.6.1. VirtualBox

VirtualBox is an open source virtualization program originally created by Sun Microsystems. VirtualBox runs on Windows, BSD, Linux, Macintosh, and OpenSolaris. It can be configured to use a downloaded FreeNAS® .iso file, and makes a good testing environment for practicing configurations or learning how to use the features provided by FreeNAS®.

To create the virtual machine, start VirtualBox and click the New button, shown in Figure 2.6.1, to start the new virtual machine wizard.

_images/virtualbox.png

Fig. 2.6.1 Initial VirtualBox Screen

Click the Next button to see the screen in Figure 2.6.2. Enter a name for the virtual machine, click the Operating System drop-down menu and select BSD, and select FreeBSD (64-bit) from the Version dropdown.

_images/virtualbox-create-name-os.png

Fig. 2.6.2 Enter Name and Operating System for the New Virtual Machine

Click Next to see the screen in Figure 2.6.3. The base memory size must be changed to at least 8192 MiB. When finished, click Next to see the screen in Figure 2.6.4.

_images/virtualbox-create-memory.png

Fig. 2.6.3 Select the Amount of Memory Reserved for the Virtual Machine

_images/virtualbox-create-hard-drive.png

Fig. 2.6.4 Select Existing or Create a New Virtual Hard Drive

Click Create to launch the Create Virtual Hard Drive Wizard shown in Figure 2.6.5.

_images/virtualbox-create-hard-drive-file-type.png

Fig. 2.6.5 Create New Virtual Hard Drive Wizard

Select VDI and click the Next button to see the screen in Figure 2.6.6.

_images/virtualbox-create-storage-type.png

Fig. 2.6.6 Select Storage Type for Virtual Disk

Choose either Dynamically allocated or Fixed-size storage. The first option uses disk space as needed until it reaches the maximum size that is set in the next screen. The second option creates a disk the full amount of disk space, whether it is used or not. Choose the first option to conserve disk space; otherwise, choose the second option, as it allows VirtualBox to run slightly faster. After selecting Next, the screen in Figure 2.6.7 is shown.

_images/virtualbox-create-disk-filename-size.png

Fig. 2.6.7 Select File Name and Size of Virtual Disk

This screen is used to set the size (or upper limit) of the virtual disk. Set the default size to a minimum of 8 GiB. Use the folder icon to browse to a directory on disk with sufficient space to hold the virtual disk files. Remember that there will be a system disk of at least 8 GiB and at least one data storage disk of at least 4 GiB.

Use the Back button to return to a previous screen if any values need to be modified. After making a selection and pressing Create, the new VM is created. The new virtual machine is listed in the left frame, as shown in the example in Figure 2.6.8. Open the Machine Tools drop-down menu and select Details to see extra information about the VM.

_images/virtualbox-new-vm.png

Fig. 2.6.8 The New Virtual Machine

Create the virtual disks to be used for storage. Highlight the VM and click Settings to open the menu. Click the Storage option in the left frame to access the storage screen seen in Figure 2.6.9.

_images/virtualbox-vm-settings-storage.png

Fig. 2.6.9 Storage Settings of the Virtual Machine

Click the Add Attachment button, select Add Hard Disk from the pop-up menu, then click the Create new disk button. This launches the Create Virtual Hard Disk wizard seen in Figure 2.6.5 and 2.6.6.

Create a disk large enough to hold the desired data. The minimum size is 4 GiB. To practice with RAID configurations, create as many virtual disks as needed. Two disks can be created on each IDE controller. For additional disks, click the Add Controller button to create another controller for attaching additional disks.

Create a device for the installation media. Highlight the word “Empty”, then click the CD icon as shown in Figure 2.6.10.

_images/virtualbox-vm-settings-storage-add-iso.png

Fig. 2.6.10 Configuring ISO Installation Media

Click Choose Virtual Optical Disk File… to browse to the location of the .iso file. If the .iso was burned to CD, select the detected Host Drive.

Depending on the extensions available in the host CPU, it might not be possible to boot the VM from an .iso. If “your CPU does not support long mode” is shown when trying to boot the .iso, the host CPU either does not have the required extension or AMD-V/VT-x is disabled in the system BIOS.

Note

If there is a kernel panic when booting into the ISO, stop the virtual machine. Then, go to System and check the box Enable IO APIC.

To configure the network adapter, go to Settings ➞ Network ➞ Adapter 1. In the Attached to drop-down menu select Bridged Adapter, then choose the name of the physical interface from the Name drop-down menu. In the example shown in Figure 2.6.11, the Intel Pro/1000 Ethernet card is attached to the network and has a device name of em0.

_images/virtualbox-vm-settings-network-bridged.png

Fig. 2.6.11 Configuring a Bridged Adapter in VirtualBox

After configuration is complete, click the Start arrow and install FreeNAS® as described in Performing the Installation. After FreeNAS® is installed, press F12 when the VM starts to boot to access the boot menu. Select the primary hard disk as the boot option. You can permanently boot from disk by removing the Optical device in Storage or by unchecking Optical in the Boot Order section of System.

2.6.2. VMware ESXi

ESXi is a bare-metal hypervisor architecture created by VMware Inc. Commercial and free versions of the VMware vSphere Hypervisor operating system (ESXi) are available from the VMware website.

Install and use the VMware vSphere client to connect to the ESXi server. Enter the username and password created when installing ESXi to log in to the interface. After logging in, go to Storage to upload the FreeNAS® .iso. Click Datastore browser and select a datastore for the FreeNAS® .iso. Click Upload and choose the FreeNAS® .iso from the host system.

Click Create / Register VM to create a new VM. The New virtual machine wizard opens:

  1. Select creation type: Select Create a new virtual machine and click Next.

    _images/esxi_create_type.png
  2. Select a name and guest OS: Enter a name for the VM. Leave ESXi compatibility version at the default. Select Other as the Guest OS family. Select FreeBSD12 or later versions (64-bit) as the Guest OS version. Click Next.

    _images/esxi_name_os.png

Virtual HPET hardware can prevent the virtual machine from booting on some older versions of VMware. If the virtual machine does not boot, remove the virtual HPET hardware:

  • On ESXi, right-click the VM and click Edit Settings. Click VM Options ➞ Advanced ➞ Edit Configuration…. Change hpet0.present from TRUE to FALSE and click OK. Click Save to save the new settings.
  • On Workstation or Player, while in Edit Settings, click Options ➞ Advanced ➞ File Locations. Locate the path for the Configuration file named filename.vmx. Open the file in a text editor and change hpet0.present from true to false, then save the change.

Network connection errors for plugins or jails inside the FreeNAS® VM can be caused by a misconfigured virtual switch or VMware port group. Make sure MAC spoofing and promiscuous mode are enabled on the switch first, and then the port group the VM is using.
