Old jail mounts ?

[vom]

Hello,

I searched through the forums already and didn't see anything resembling my question.

I've upgraded FreeNAS several times (from the GUI - all of which worked - awesome !)

At one point I played around with plexmediaserver, but removed it.

I just upgraded to 9.3 (great job by the way) - and I see I still have (what appears to be) older version jail mounts:

bigdisk/bigshare/jails 640G 86M 640G 0% /mnt/bigdisk/bigshare/jails

bigdisk/bigshare/jails/.warden-template-9.1-RELEASE-amd64 640G 347M 640G 0% /mnt/bigdisk/bigshare/jails/.warden-template-9.1-RELEASE-amd64

bigdisk/bigshare/jails/.warden-template-9.1-RELEASE-amd64-pluginjail 641G 913M 640G 0% /mnt/bigdisk/bigshare/jails/.warden-template-9.1-RELEASE-amd64-pluginjail

bigdisk/bigshare/jails/.warden-template-pluginjail-9.2-x64 641G 692M 640G 0% /mnt/mnt/bigdisk/bigshare/jails/.warden-template-pluginjail-9.2-x64​

Are these normal ? I don't seem to see any errors or warnings.

Is there a reason, perhaps for some kind of backwards compatibility that they remain ?

If they aren't needed, I'd love to remove them (if nothing else to clean up df / View Volumes).

If I can remove them - what would be the 'correct' way ?

Thanks in advance.
