How to remove a (plugin) jail from FreeNAS I'm running FreeNAS (v9.2.1.9) as a file and media server and have several jails installed, some of them as plugin jails others as "standard" jails. After I had replaced one of the plugin jails by a "standard" (hand made) jail, I wanted to remove the old plugin jail. I rushed ahead by just deleting the dataset on which the plugin jail was installed, but the plugin jail is still showing up in the web interface under the "Jails" tab. So I assume at some place there is still some residuals of the plugin jail left. Since I have no idea what the plugin installer did and there is no built-in way to remove a plugin jail, I'm stuck with this "unclean" removal. Now I'm wondering, how can I remove a plugin jail from FreeNAS completely? What additional cleanup is required in my case?

I had a similar issue on FreeNAS 9.3 and could not find a remove button. I got it to disappear by going to the jails volume, and removing the directory which held the jail:


# rm -fr /mnt/black/jails/.couchpotato_1.meta/


This also removed the complaints during boot. No negative side effects seen yet.
