My FreeNAS USB stick died and I had no backup of the FreeNAS configuration file (school boy error).
I’ve imported my ZFS pool and imported my jails (can’t remember how – It was a long time ago) but I’m unable to update my jails software because they weren’t installed via plugins.
Install the plugin correctly, copy the plex data from the old jail to the new jail (from Outside the jails!)
# cp -R /mnt/zfs1/jails/plexmediaserver_2/var/db/plexdata/Plex\ Media\ Server/ /mnt/zfs1/jails/plexmediaserver_1/var/db/plexdata/Plex\ Media\ Server
From inside the new jail
# cd /var/db/plexdata/
# chown -R plex:plex Plex\ Media\ Server
plexmediaserver_2 is the imported jail
plexmediaserver_1 is the new jail
Unsure why the numbers are counter to what you’d expect.
