Safe to remove old plugin jail volumes ? Which ones ?

[vom]

Hello,

I've had my filesystem going for quite some time through different versions of FreeNAS. In that time I've accumulated multiple mount points for plugin jails and templates. It seems like I should be able to remove some of these (i.e. 9.1, 9.2). I'm currently on 9.3-STABLE. So my question is - if I can remove the old ones - which ones should I keep as current / 9.3 (I am running Plex). Here is a df showing what I'm talking about.

Code:

[vom@freenas ~]$ df -h | grep jails

Assuming it lets you, it should be safe to remove the datasets for the 9.1 templates. I'm pretty sure that 9.3 still uses the 9.2 templates.
