I'm in the midst of designing a storage appliance to house client offsite backups which will replicate to one another bi-coastal (freenas replication). The files housed on the storage appliance would range in 10GB - 50GB in nature, typically no smaller and are 95% writes versus reads. There is...
Roughly one year ago I build a new FreeNas machine because I would like to have a remote backup of my data. I managed to replicate my data from the old FreeNas server to the new FreeNas server. Then the old FreeNas server moved to a friend. Unfortunately I never got remote replication to work as...
Hello everyone.
My google foo is letting me down.
I have two freenas systems and i'm replicating one server over the internet with a second one.
This is done with seven datasets, every hour.
Everything seems to be going great for a while now, but I'm getting ten to 30 mails a day stating...
I'm using replication to back up one FreeNAS 9.10 server (call it alpha) to another (call it beta). All that appears on beta is an empty directory tree. No files!
I followed the User Guide, setting it up. I made sure all old snapshots on both alpha and beta were destroyed. The Status field on...
I am attempting to figure out how to get two FreeNAS units to talk to each other over the WAN. I'd like to create replication tasks from my onsite FreeNAS to my offsite FreeNAS. The onsite sits behind a Sonicwall and has a static public IP address. The offsite has none of that stuff.
Obviously...
Not new to FreeNAS, but new to replication. My question is: if the source and destination datasets are both lz4 compressed, is it necessary/advised to use stream compression?
I read somewhere that newer versions of ZFS are capable of sending the snapshots as they are on disk (compressed) and...
Hi there,
So, i am wanting to repurpose old server hardware for a offsite FreeNAS backup solution. In order for me to get the hang of the replication functions and limits I've installed FN11.1 in a VM. And so my journey started.
The now situation:
I am able to send snapshots over to my target...
When doing a replication from FreeNAS 9.3 to 11.1 and where the target volume has been enabled for encryption, ZFS reliably panics:
panic()
dblfault_handler()
Xdblfault()
--- trap 0x17
vdev_queue_io_to_issue()
vdev_queue_io_done()
zio_vdev_io_done()
zio_execute()
zio_vdev_io_start()...
I have a source FreeNAS system and a target system. The sole purpose of the target system is to accept replications from the source system -- to act as a backup. I created identical pools on each system and set up replication from source to target. I didn't create any datasets nor set any...
Hello:
I have two FreeNAS servers (9.10) in different countries, let's call them A&B.
I want to have them replicate each other, and I can run that with test servers just fine.
But B is new/empty and A has 6 TB of data and a slow internet connection (just 1Mb/s upload), so it is really a...
Hey everyone,
I've been away for a while because of school but am going to have a couple of days off and wanted to make the most of it by upgrading my FreeNAS boxes. I wanted to post my situation and run my plan by others as I'm not very up-to-date on the latest release of the 11 stable train or...
Hi,
I have two FreeNAS instances, one running 11.0-U2 on a VM and one running 11.0-U4 on bare metal. I want to copy over the >1T of data from the VM to the bare metal system. I've read in the User Guide about Replication and I see that I need to generate an auth token on the target (bare...
Hello! I have been messing around with FreeNAS for a few months now. It's a solid product and has been working fairly well for me. I have had a recent issue with the flash drives I was using to run the OS on. The problem involved me losing all access VIA the web and console locking up. With an...
Hello,
This is a very new installation of freenas 11. This machine is doing backups from a remote NAS using replication task, no sharing, no VMs, only a pool with the replication data. I have a lot of snapshots replicated here, i can see data also. But suddenly, this message is appearing in...
I have two identical systems running FreeNAS. The Main system is used for storage; the other is for replication from the main system.
What is the process for making the replicant into the primary system (for example, in case the primary is damaged)?
Hello,
We are using some virtualised FreeNAS installations (Build FreeNAS-11.0-RELEASE (a2dc21583)) on Dell servers amd ESXi 6.5 hypervisors with enterprise SSDs on LSI 9271 IT-Mode HBAs passed-through to the FreeNAS VMs.
So far they have proven very dependable.
I successfully replicated a...
I've tried to look up the protocol and therefore any specific hardware choices relevant to ZFS send/receive for replication, but can't find details beyond a statement that ZFS uses a "serialised" data stream (which implies its own protocol not SMB/NFS/whatever).
I've got to set up a new FreeNAS...
Hi,
I have created a zvol, which is connected via iSCSI from a Mac. I setup auto-snapshots and a local replication task to a external backup drive. I have done the same procedure on a regular dataset and I received no errors. The data (non zvol replication) appears intact.
However, when I...
Hi! First of all I apologize in advance if my question could sound silly, but I'm banging my head on the wall for too much time.
I'm using two FreeNAS 9.10.U3 boxes, let's call them A and B, to replicate a couple of datasets. A and B are connected via 1 Gbps link just across the room.
I've set...
(If this isn't the most appropriate place to put this post, I apologize)
I'd like to talk about making replication between FreeNAS hosts better and more reliable in the next (real) release.
I've had several bad experiences with replication in the past on FreeNAS 8.x and 9.x, enough that I...
When I make terabyte-sized changes so I can see how replicate performs, it doesn't perform as well as I expected.
My source and target machines are connected via Intel 10gb connections. iperf tells me that I can get well over 9gb/sec.
My replicate goes from 1gb/sec to 1.5gb/sec. I'm not sure...
Hello All,
Running: FreeNAS-9.3-STABLE-201602031011
A volume (/data) has been migrated to a different FreeNAS installation using Replication. The volume exists and there is one snapshot.
Now I want to use (/data) as a production volume. I am deleting the replication job.
How can the...
I am having not really a problem, but just something I don't understand.
I recently moved my backup FreeNAS server (see sig) to a remote location and have everything setup and working fine. I can confirm SSH is working.
On the first night it was to backup, I got an error similar to this:
I...
I have three 80 TB FreeNAS 9.2.4 servers named "Server", "Backup1", and "Backup2". Server contains a single dataset, "Volume". Server is in use 24x7, and Backup1 and Backup2 are kept mainly offline and serve as rsync repositories for Server. Periodically, I run rsync to synchronize...
Hello. I have just switched from NexentaSTOR to FreeNAS and am very happy I made the switch. Much better performance and ease of use. I am using FreeNAS as iSCSI datastores for my VMware ESXi servers in my lab. I have a primary FreeNAS server running with Raid10 and a secondary FreeNAS server...
I have two FreeNAS boxes and am trying to sync the two. Issue I am having is that it starts working for about 300 gig, then it starts to have a "Failed Permission Denied" error in the replication status.
The sync will not work again until I play around with the settings again. Then, it works...
I've got a ~550GB snapshot that I'm attempting to replicate offsite for the first time, and finding that when the job gets interrupted, all progress gets erased and requires restarting. In the last two weeks, I haven't managed to get the whole thing sent, and the multiple daily restarts are...
I have tried to setup the replication according to the documentation and am having issues.
Build: FreeNAS-9.10.1-U4 (ec9a7d3)
NAS-01: Push
NAS-02: Pull
Directions: http://doc.freenas.org/9.3/freenas_storage.html section 8.2
Issue:
The replication from NAS-01 to NAS-02 is failing. I am getting...
Hi all,
I'm having some questions on setting up a replication "workflow" on the FreeNAS systems that i have deployed, i really need some advice on how to proceed.
Hope the forums collective knowledge can pitch in here.
My goal is to replicate the snapshots from PUSH 1 and PUSH 2 to one single...
My system specs for both my main server and my backup server are in my sig.
I have found multiple threads on this issue but most are from around Feb/Mar of 2016.
Here, here and here. I thought I would ask since most of those threads say it was something to be fixed by a software update. Both...
Hi,
I am trying to configure local replication to another disk.
I created snapshot task, specified localhost and added the public key but never get it to work. I tried deleting and recreating the snapshots but no luck. Any thoughts?
Hello,
The system was unable to replicate snapshot vol1 to...
I am trying to understand how ZFS replication works on FreeNAS 9.2.1.9 (possibly it is the same as 9.3). My conclusion from reading the user manual is that FreeNAS uses vanilla zfs send command possibly with few switches and schedules it as a cron job. Apparently it does that in semi-incremental...
Hey there,
for spindown- and performance-reasons, I´d like to move my jails to the system dataset.
I got a NAS-System consisting of a (high write endurance) SSD with 250Gb, that I planned to use as system disk and for my jails.
FreeNAS is installed to this SSD and uses 1,14GB of this SSD (what...
Hi all,
I have 2 freenas servers (Server1). The first one has 1 Zvol shared via iscsi to a esxi server. This zvol is replicated to the second server (Server2) via snapshots and replication tasks.
It seems that the replication is working as expected, because the zvol in the replicated freenas...
Howdy all,
Ive been looking around the forums here trying to see if there is a way to do a snapshot replication tasks between to pools on the same node (this is for a home setup). Now yes, I know you can setup the GUI replication task and just point it to loopback and apply the SSH key...
Hello, my FreeNAS 9.10.1 (latest updates applied like month ago) started to crash pretty ugly. I suspect it's because of the replication task, which never caused problems (pool1 -> pool2, both local) but suddenly, after having rebooted the box 2 days ago, this happened:
1. Reboot triggered...
Situation:
2 FreeNAS units Primary and Backup (FreeNAS-9.10-STABLE-201606270534 (dd17351))
Periodic Snapshots on Primary unit replicating to Backup unit - No Issues, works great.
Primary unit CIFS share - I can see all files and go back to any available snapshot and pull a previous version of a...
I have two FreeNAS servers running the latest 9.10 build.
Once a snapshot replication has completed, is it possible to change the replicated share on the receiving server into a normal writable shared dataset?
This will be a once of task, scripts or scheduled tasks wouldn't be required.
