As a pre-requisite, consider reading my TrueNAS SCALE virtualization guide! https://www.truenas.com/community/resources/getting-started-with-virtualization-on-truenas-scale.214/ This resource is meant to be a series. Part 1 will cover both the theory behind what I mean by Datacenter-in-a-box...

So i have 2 FREENAS machines, One is the Primary storage and the second one is going to be its backup. I want to backup all the data (52TB) to the Backup machine and then keep it in sync with the primary server. After researching ZFS replication seemed to be the most suitable solution. Ive set...

I hope you can help me understand what's going on here with my original dataset using lz4 and the replicated one using gzip-9. Two FreeNAS servers, 1# and #2, both has a new volume with nothing special going on. The dataset in question that is being replicated has all kinds of different data...

Hello, I have been researching this for a while and still am not very clear. What I have at the moment is two freenas servers running 11.2 U5 (Server A and Server B). Server A is my main server with plex, transmission and data sets, the pool (Nas1) is a mirrored stripe (6 x 3TB HDD), about 50%...

Trying to replicate nas1:tank/veeam to nas2:tank/veeam, but the job created nas2:tank/veeam/veeam. What's with the additional directory in the path? Also, neither here nor there since the initial replication task isn't done yet, but why do I see over 1TB in use on the target, but I still see...

I have searched Oracle zfs docs and the forum but I am still unsure regarding how to properly backup my iocage jails to a different pool so as to have a backup if I mess up or otherwise get my jails destroyed. Naively I began with a recursive snapshop task of the entire iocage/ tree and tried...

I've just upgraded from 9.10.2-U5 to 11.2-U5 and aside from kicking myself for not even considering installing each release (i.e. 11.1) along the way, everything seams to have gone perfectly fine (see below for more details of my upgrade methodology). My old Warden Jails and Plugins are back up...

Hello, we have a FreeNAS backup 'BU1' that probably will need to have its pool rebuilt because of some h/w issues. Currently there is an incremental replication established from BU1 to remote server BU2. However, probably we'd need to rebuild BU1 pool, and because the bandwidth with BU2...

I am replicating a small zvol containing a hyper-v VM that has been running off my primary FN 11.2 box on to a secondary. I need to now mount the replicated zvol in Windows but when I try to initialise the disk I get a write protected error. I remembered from one of the tutorials that...

Hello everyone, The company I work for recently took on a new client that is using FreeNAS for their shared company data. I have never used FreeNAS, so I am a complete noob, and don't really know where to start on troubleshooting the replication issues they are suddenly having. I can't seem...

This is not a question but an answer, as I stumbled several times over this problem and eventually found what I needed on google, but it was always very difficult to locate. So for everyone else who wants to replicate from their FreeNAS to a linux machine and who gets this error: cannot receive...

On May 21 I installed a SSD for the FreeNAS OS and loaded it on. It all went fairly smoothly, and all my configuration is intact and everything working smoothly. However, recently I noticed that the last snapshots to be replicated were on May 20 (although in Storage > Snapshots the date column...

Hello everyone I am hoping someone can clear this up for me, I seem to be really confused on using the replication task and am thinking of switching over to rsync. I have two servers A and B. I am looking to have server A be what I actually use and B just to be a backup, that's it. Since I...

Hi all, I've got a pair of identical FreeNAS servers running 11.1-U2 with one acting as a the primary and the other acting as a replication target for snapshots. For the past few months, replication has been failing for the original dataset (started with a 40TB quota but has since been increased...

v11.2 We are using replication to backup our production unit to a backup system. Is there a way we can configure it so that the backup unit has longer, but not unlimited snapshot retention than the production unit? (We don't want to tell the replication task to just not ever delete things and...

Hi all- I set up a replication task with two machines on a LAN that was working successfully. I recently colo'd one of the machines. I'd like to confirm that replication tasks are still working - I'm not getting any errors, which leads me to believe "yes," but I'd like to be absolutely certain...

I have a server for personal "main storage" and have set up replications to a secondary server in another building. However the replication job seems to start over and over, and I can't figure out why. There is only one snapshot in the list, and it's the same snapshot that seems to be replicated...

Hello, i've an issue with 2 identical twins SRVS, in replication (Rsync) with identical configuraion, HDDs in mirror 2TB, same compression level Iz4 - ratio 1.09x, the push has available empty diskspace 940.2gb the pull has available empty diskspace 34.7gb!!! There is no hardware error or...

Hi, I would like to replicate my FreeNAS server to another one only during the night (between 20:00 and 08:00) . How should I specify this period of time ? a single replication task that overlap midnight ? Begin Time = 20:00 and End Time = 08:00 or two replication tasks that stop and start...

Hi All, I have a freenas box running 11.0-U1 (soon to move to 11.2-U3) that is replicating datasets to a backup system on 11.2-U3. This works. I want to keep or make snapshots on the remote/destination system longer than the source. I do not wish to keep this data around on the primary for...

Hi all, I'm running FreeNAS 11.2-U2.1 on ESXi 6.5, FreeBSD 64-bit. This is not meant for production, merely to have a proof of concept before going out and buying a ton of hardware. I'm trying to get the FreeNAS box to replicate to a GCP bucket. I created a service account, gave it relevant...

Hello Freenas Forum. I have a main machine which is backed up via replication (send/receive) to another machine. They are on the same LAN and in my apartment. Both machines are on 11.2. I have configured this as no deletion of stale snapshots, no encryption and no compression. This has...

Hello! My setup is the following: 1 vdev with 3 HDDs, all 3 mirror of each other (so 3 x 3TB HDD, total available space = 3TB). 2 Drives are just going to spin all the time, mirror of each other, that's the redundancy. The 3rd drive, I'll plug it in once every now and then (say: once per month)...

I would like to know if is possible to create a script to delete snapshots on backup/replication server side. We have the option "Delete Stale Snapshots on Remote System", but this is not very secure because if we accidentally (or not) delete these snapshots on primary server, they also will be...

Hello Everyone, I am the Systems Administrator here for a medium sized manufacturing company. We currently have 2 FreeNAS 2U certified systems in different physical locations to protect against disaster scenarios. Both systems host 2 ZVols over iSCSI to 1 VM Host each. Lets call these sites...

Hi - I have two FreeNAS FreeNAS-11.2-RELEASE-U1 systems set up to experiment with snapshot replication and system recovery before I implement at work. I have a dataset on the source system with 15min snapshots an 1hr retention, this is all working fine. I have configured replication to the...

I've mentioned this at least once before in another post and either got the feeling nobody else felt like this was an issue or they didn't quite appreciate the implication so thought I'll make a specific post about it so you guys can either put my mind at rest or we can conclude this is an issue...

I'm pushing a 4TB backup from A to B. It's over a 100Mbps link so it takes a while. After two days I thought it would be a good idea to see the file structure actually being created on the target server - but it's empty! So I searched and found what I assume is the solution to my problems...

TLDR; So the question is: Why are two of these datasets replicating more than once to different datasets? And most importantly, how do I stop it from happening? I have 6 replication jobs set up and two of them are acting strangely. They are replicating themselves to the wrong dataset, in...

I've been using replication tasks for some time, but thus far always used the manual setup, which was/is working flawless. It's vacation time and I decided to try out the semi-automated replication setup but can't get it to work. Upon save I always get: Failed to connect to remote host ws://<<<...

Hello, there´s one thing i don´t get about snapshot replication. Lets say I have a daily snapshot task of my Datapool. Everyday this snapshots are replicated to another server. Now lets assume my pool is heavily degraded or lost or I want a new, bigger one. Happily I have my replicated...

All, I have two FreeNAS boxes that replicate a small number (<5) datasets over an internet connection. Both boxes are running latest 11.2 and are powered by 16GB RAM and a low power Atom CPU. As they are used to store/secure some family pictures and stuff, the load is very low. When connecting...

I have a master FreeNAS system backing up to two systems via replication: a backup and disaster recovery. On both the backup and DR FreeNAS systems the replicated datasets appear correctly transferred in the web GUI (besides some minor discrepancies I go over here...

Hi All, How do you guys go about setting up a freenas server to be used as production in case the main server fails? I am thinking maybe using replication in the first place, Ideally I would like something with minimal changes required so everyone would not notice I change the server. And...

I have three FreeNAS servers. Master has replication setup to both a backup FreeNAS and a disaster recovery (DR) FreeNAS. Before setting up replication on master I transferred the main 'tank' pool's latest snapshot to backup and DR manually using zfs send recv piped through netcat--replication...

Hi, I have the problem that child datasets of readonly datasets are not mounted and cannot be mounted: cannot mount '/mnt/tank/foo/bar': failed to create mountpoint The freenas box receives replication streams from another freenas box, which works fine. I also understand why it's set readonly...

Hi, after a server reboot the replication stopped working. Storage → Replication Tasks → Status: Failed: ssh: connect to host example.com port 12345: Operation timed out It worked fine before the reboot. Connecting manually works, however: ssh -i /data/ssh/replication -p 12345 example.com...

Hi all, I will be creating two FreeNAS instances, one with 30tb and the other with 4tb. The 4tb one will be in an office environment. Due to the data retention requirements, it will have hourly snapshots running on it with a 3 month retention. The 30tb one will be in a remote location. We would...

I am pretty new to FreeNAS. I'm having a problem setting up snapshots, they don't seem to be doing anything. On the snapshot list page, all it says is "An error occurred", there is no error number or details. I setup the snapshot to run recursively, once every day, and retain for 2 weeks. I...

How do I get FreeNAS GUI to continue incremental zfs replications after moving a data set to a new server? The GUI wants to start from the beginning and resend the entire dataset. Perhaps there is a file somewhere that has the most recent snapshot sent that I can manually edit? Scenario...

Hello: I have two identical FreeNAS systems, about 100TB in capacity, that have been in production for several years now. The master has one main export, which is exported via SMB to about 30 windows clients. Permissions were set as "Windows" at creation time, but were also set as guest...

Hello, I have been using FreeNAS for regular home storage for a while now. I recently decided to add a replication FreeNAS and following the instructions. It appears to be working. The source computer sends the Snapshots over to the destination. There are no errors and sometimes I even catch...

Hi All, I'm in the process of testing FreeNAS as an alternative to my WHS2011 - I've reached the 2TB limit on it and need something to replace it. This is for a home system for photos, music, films, ISOs, etc, and some data. My current WHS setup is effectively: 2 x 2TB disks in mirror (using...

Hello, I am unsure how I should formulate the zfs send zfs receive command to replicate all data from my main FreeNAS box(Freenas1) to a new temporary FreeNAS box(Freenas2). Here's the information I believe is relevant: Freenas1 has the pool name Volume1 with a primary dataset named Volume1...

Hi all, I've got a FreeNAS 11.1 file server, which I'm shipping to New Zealand (I'm moving there). It has a single raidz2 volume, based around 4 1TB SSDs. As insurance for the data, I've bought 4 new 1TB SSDs and my intention was to create a backup. I thought the correct way to do this was to...

Hello, I have an existing FreeNAS server running the latest 9.4 software (96GB RAM, 6 - 4TB SAS Constellation Drives, 2 - 128GB Enterprise SSD for caching) that is getting full...so I upgraded my existing local BackUp FreeNAS server with 4 - 8TB Seagate Pro drives with 2 - 128GB Enterprise...

I just set up a new replication server, and have been testing it. My main server and this are both using 11.1-U5, both enterprise hardware, and all features enabled. I ran zfs send on the main server and zfs receive on the new backup server, and deliberately killed the process after a while to...

I need some help troubleshooting a deadlock on by backup machine. During its incremental replication all processes accessing the data set end up in a lock on rll->rr_ as reported by a ps -axHl -O lwp in the nwchan field. Set up: master is doing periodic snapshots (multiple per day, keeping...

Hallo zusammen, wir nutzen schon seit einiger Zeit das wunderbare FreeNAS (nachdem eine Mallware unsere Laufwerke verschlüsselt hatte, durfte ich auch die geniale Möglichkeit nutzen, auf einen Snapshot wieder zurückzuspielen, so das nach 20 Minuten der ganze Hokuspokus vergessen war! :-) Jetzt...

I have two Freenas machines. My primary machine is connected to my LAN network and I have a secondary machine at a friends place which I use as a backup destination for a replication task running on my primary machine. I believe I have this finally working as intended. So far so good ... The...
