Couldn't extract UUID (mergerfs)

Hi,

after the most recent update and a reboot, it seems mergerfs isn't working anymore. When trying to open the file systems tab, I get:

Zitat

This is the Mergerfs volume. The content is still there in the data discs, but I can't access it throuth mergerfs.

If it is any help, this is the ouput of "omv-showkey mergerfs":

PS: I just noticed in the "Disks" tab that my system disk now is called "sdc" rather than "sda" as before, so the sequence of the disks seems to have been messed up. Could this have anything to do with my problem?

When I try to restart the mergerfs pool, it's

Thanks for your reply! I'm not sure if I understood you correctly; in the mergerfs UI I can only select drives from the list and not enter the path by hand.

Anyway, I selected the proper drives again and tried to apply; the result was:

The "merged" directory (6418...) exists; should I delete it? Some docker containers operate on it and created some directories; could this cause problems?

Ah, I didn't realise the field can be edited.

The result, however, is the same:

Aaron: The error I posted happens when I try to apply the changes. So after the reboot, the changes are still pending, and everything is as before.

Should I delete the folder 6418...? Or is this goint to cause more trouble?

Gderf: Funny, the "delete" icon is greyed out for my pool. (all other icons are active).

You mean delete all the shares referencing the merged file system? That delete button is also greyed out...

I stopped the docker containers using the merged FS, but that didn't do it.

If the pool can't be restarted after your change, it usually fails. Not sure how the plugin can fix that. That is why rebooting is usually easier and when you apply after the reboot, it is restarting the same pool.

Was this pool created from an OMV 5 to 6 upgrade? I expect the changes to still be pending. And as I said above, restarting the same pool after the reboot should have less issues.

I tried to restart the pool after a reboot. Same error.

Is this a pool that was upgraded from omv 5 to 6?

Yes. Do I have to do something to "convert" an OMV 5 pool?

OK, now I'm really confused because after another reboot everything is working again - and everything I changed was stopping the docker containers before the reboot.

Thanks to both of you for helping! If it turns out that something is still broken, I'll be back.
