FreeNAS 11.1 U7: Install Syncthing in Jail

As part of moving to a new FreeNAS box, I want to replicate data from the old (nas2, running FreeNAS 11.1 U7) to the new (nas3, running FreeNAS 11.3 U5) machine. During the initial phase nas2 will still be my primary storage location. Think of this as something like a burn-in to ensure that there are no dead-on-arrival components in the new box, esp. hard disks of course. This is planned to last for at least two months and I want all my data synchronized constantly.

The solution I laid my eyes on is Syncthing and I want to run it in a FreeNAS jail on both systems. On the new system the installation was smooth, but on nas2 it was not possible to even create a jail. It turned out to be a setting that had not been migrated from the original FreeNAS 9.3 installation, which had been the initial version of FreeNAS on nas2.

All that had to be done was fix the “Collection URL” setting in the jails configuration as shown below.

  1. Go to “Jails / Configuration”
  2. Switch to “Advanced Mode”
  3. Make sure that the URL contains “11.1” (was “9.3” before on my system)

The next step was to install Syncthing with pkg. The problem with FreeNAS 11.1 is that the underlying FreeBSD is no longer maintained (EOL) and therefore no package repository exists for this version. The workaround is to forcibly switch to an existing repository, even if it does not match the FreeBSD version. I am ok with that, as long as only applications and not OS tools are installed (you should carefully think, whether this is also ok for you!). To do this, issue the following command:

# pkg bootstrap -f

You will get a warning about different OS versions and need to confirm that you want to continue. Once this is complete, install Syncthing with

pkg install syncthing

You get the same warning as just before and need to confirm the installation.

From here, you can just continue with the normal process of setting thins up. A good starting point might be the following YouTube video.

FreeNAS Upgrade from 9.2.1.7 to 9.10.2-U2

I have been an extremely satisfied user of FreeNAS for many years, but had not updated my system for quite a while. Having a free Sunday was the perfect opportunity to do just that.

There were two steps involved: First go to 9.3.1 and then to 9.10.2-U2. As my box sits in the basement and is headless, I opted for update via GUI and it went extremely well.

The only issue was that on 9.10.2 the jail template list was empty. A quick online search revealed that this was, unfortunately, expected. But on the other hand, in such a case there is a good chance, that someone else has already found a solution.

But it all proved a bit more challenging than expected. And  nothing I found worked completely. So I ended up with a combination of things from other people (in particular this link) and my own discoveries:

  • I deleted the ZFS volume .warden-template-standard via the web UI
  • Then from the command line the ZFS was re-created with
    zfs create zpool/jails/.warden-template-standard
  • Deleted the template
    warden template delete standard
  • Re-created the standard template
    warden template create -nick standard -tar http://download.freenas.org/jails/10/x64/freenas-standard-10.3-RELEASE.tgz

At this point everything should have been good – but it was not. Still no template showed up when I tried to create a new jail. So I added a jail template in the web UI, too.

The URL is exactly the same as for the command line above.

With this I was able to create a new FreeBSD jail.
