We are pleased to announce the general availability of FreeNAS 11.1. This release delivers many performance improvements, new and updated drivers, new features and enhancements, and bug fixes. FreeNAS 11.1 can be used and distributed free of charge, and updates are freely available.

Operating System

FreeNAS 11.1 is based on the FreeBSD 11.1-STABLE operating system, which includes numerous performance improvements, new and updated drivers, new features, and bug fixes.


OpenZFS has seen many improvements. Users will notice a significant speedup when listing a large number of snapshots or deleting multiple snapshots and large files.

The scrub and resilver algorithm implement substantial speed improvements which will be most noticeable on fragmented pools.

Resilver Priority has been added to Storage. Resilvering, which rebuilds the storage array, can now be run at a higher priority at configurable times and days of the week.

Hardware Support

The hardware watchdog has been reenabled for recent firmware versions of AsrockRack C2750D4I. The BMC bug which required the watchdog to be disabled is resolved with the 00.35.00 or newer BMC firmware version.


The Identify Light button has been added to identify a system in a rack by flashing its Unit ID light.

Cloud Support

Cloud Credentials has been added to System, providing a secure connection with cloud service providers. Supported services include Amazon S3, Azure Blob Storage, Backblaze B2, and Google Cloud Storage.

Cloud Sync has been added to Tasks, giving the capability of synchronizing files or directories with remote cloud storage.

Virtual Machines

VMs have received significant improvements, including:

  • selecting which NIC is used by the VM, and setting the MAC address for the VM NIC.
  • specifying the sector size used by the emulated disk.
  • selecting the VNC screen resolution, the IP address to bind to, the VNC password, and the option to use the Web version of VNC.
  • the option to create a Docker instance based on RancherOS.


  • The Netdata real-time performance and monitoring system has been added.
  • The SNMP MIB has many improvements, including the ability to send SNMP traps for new alerts.

Time Machine

Support for per-backup OS X Time Machine quotas has been added.


The Send Test Alert button has been added to Alert Services, making testing of notification services simpler.

The complete list of features is available at http://doc.freenas.org/11/intro.html#new-features-in-release.
