SOLVED Can't find my media!

[Schnurdle]

After my system drive ran out of space, and finding out that you can't expand it without doing a fresh install, I decided to try moving my jails to the Media volume.

/Media/Stuff contained folders for "_Film", "_TV" and "_Music", so I created a new folder, "_Jails", and switched the Freenas Jails configuration over, then all my jails magically disappeared!

After various attempts at "rsync"ing the existing jails over, I have now got nearly where I want to be (apart from a plugin that can't be removed because its jail doesn't exist), only to find that over a terabyte of media has disappeared along the way!

Here is a dump of zfs mount points:

mnt/Media seems to contain 1.28T of data that I can't see.
How can I get it back?

Were you able to figure this out?

 

[Schnurdle]

Nope.
Found some other posts mentioning a bug that deleted the contents of whatever folder/mount you reconfigure the jails to use, but other than that, nothing.
Any ideas?

I'm going to guess that you had a directory of Media/Stuff, and you then created a dataset of Media/Stuff. When you do that, the directory disappears. Its contents are still there, but you can't see it any more. Try this:

• Stop all your plugins and other jails
• From the cli, do "zfs unmount Media/Stuff/_Jails", then "zfs unmount Media/Stuff"
• See if your media subdirectories have reappeared.

 

[Schnurdle]

All jails stopped.

[root@freenas ~]# zfs unmount Media/Stuff/_Jails
cannot unmount '/mnt/Media/Stuff/_Jails': Device busy

Suggestions please!

What happens if you unmount the Storage in the GUI? (See Figure 13.2d at http://doc.freenas.org/9.3/freenas_jails.html#add-storage).

All the jails are stopped, so no storage to unmount in the GUI.

Did you figure this out?

Yes.

I opened up the Storage page in Figure 8.1k, then deleted all the jail related datasets from Media, and all my media came back!
Then I trashed all the system datasets and recreated the system volume after provisioning more storage.
After a few times resetting to factory defaults and reloading a previous config that I had conveniently saved earlier, the jail warden dataset magically reappeared in the new system volume and I was able to reinstall all my plugins one by one.
A couple of plugins originally had to be installed as customplugin_1 and 2, but now seemed to install okay via the plugin route.
I created the missing custom jails just to delete them again to tidy up the plugin list, and everything is back to working order.

Hope this helps.

Thanks for reporting back, it could be helpful if I have a similar problem!
