iocage destroy failure (legacy plugin)

[warrenmatty]

Hello,

version: FreeNAS-11.2-U8

I've replicated a local data set and then 'rollbacked' a snapshot to restore jails. Everything was successful with exception of a really old plugin. At one point I had the plex-plexpass plugin installed. This was removed well-before the replication and snapshot but for some odd reason this plugin restored when I restored a recent snapshot. When I attempt to destroy the corrupt jail the error I get from both the cli and gui is: "plex-plexpass is missing it's configuration, please destroy this jail and recreate it."

Should I delete the dataset or what's the best way forward for destroying this corrupt plugin/jail given that iocage destroy plex-plexpass fails? Here is the trace log:

Code:

sudo iocage list
plex-plexpass is missing it's configuration, please destroy this jail and recreate it.

This will destroy jail plex-plexpass

Are you sure? [y/N]: y
Partial UUID/NAME supplied, cannot check for dependant jails.

Proceed? [y/N]: y
Destroying plex-plexpass
plex-plexpass is missing it's configuration, please destroy this jail and recreate it.

The User Guide does make the point that rollback carries with it some risk and that cloning the dataset is the recommended approach. I'm curious to see how this gets resolved, if at all.

 

[warrenmatty]

That's not the best news. Am I wrong in thinking this is a issue/limitation of freenas and not zfs?

 

[warrenmatty]

Well, I navigated to /mnt/<dataset>/iocage/jails/plex-plexpass and noticed the directory was empty. I removed the plex-plexpass directory and then deleted the plex-plexpass iocage jail dataset rebooted and the issue is gone and iocage list works correctly now. I doubt this is an approved method, but posting for others that may be considering a complete rebuild to resolve this kind of issue. I'm finding that the freeness plugins are kind of an always out of date cancer. I say that because all of my other jails were created manually and they all restored fine under the snapshot rollback.

Glad you got it sorted. The Plex plugin hasn't been updated for some time now. The other issue is that Plex metadata is stored within the plugin jail, which can be a major pain if the jail gets hosed. If you want to be on a current version of Plex and keep your metadata outside the jail, I would encourage you to have a look at @danb35's scripted Plex resource.

I appreciate the response! Yeah, I ditched the plugins awhile back and installed and configured all of my applications manually(Plex included), so I could keep them up to date. Take care.
