I recently updated one of my FreeNAS 9.3 servers to 9.10 and for some reason I was unable to use FreeBSD 10.3 as the standard jail.

After looking online I found that someone had deleted the .warden-template-standard dataset to get their jail working again, so I went to the Storage section of the FreeNAS web interface and deleted the .warden-template-standard dataset.

• Once the .warden-template-standard was deleted, I tried to recreate a standard jail, but the creation failed with the error message:
  

  Unable to find template
  

• I then went to the Shell and tried to recreate the standard jail:
  

  warden template create -nick standard -tar http://download.freenas.org/jails/10/x64/freenas-standard-10.3-RELEASE.tgz
  

• Creating the jail failed because apparently warden still thinks the standard template still exists. I then tried to delete the standard template with warden:
  

  warden template delete standard
  

• Unfortunately the template couldn't be deleted because warden was looking for the .warden-template-standard dataset, and that had been deleted earlier.

The Fix¶

• As it turns out, the utility that FreeNAS uses to manage jails also manages the ZFS datasets for the jails as well.

• In order to fix the problem I needed to recreate the .warden-template-standard:
  

  zfs create zpool/jails/.warden-template-standard
  

• Then use warden to delete the standard template
  

  warden template delete standard
  

• Then recreate the standard template:
  

  warden template create -nick standard -tar http://download.freenas.org/jails/10/x64/freenas-standard-10.3-RELEASE.tgz
