openmediavault shared folders no file system backend exists

Hi!

7.7.9-1 (Sandworm)`

Linux 6.12.25+rpt-rpi-2712

My openmediavault was running as usual, I could access all shares apart from that I was missing the recycle-bin on some shares.

Thought that maybe I had configured them to not use any recycle-bin.

Went to the dashboard, and was greeted with 'internal error 500' when trying to check storage/file systems and shared folders

no file system backend exists (zfs)

Thought there maybe was a bug in one part of the system so I installed the updates 60+

No change!

Can anyone help?

Saw that I've got backup files on the unit, can I somehow use them to restore my drives and data?

Hi Chente!

No, it is not a new installation, had it for many years, only installed the suggested updates.

Now, it boots, I can access the Dashboard, but not storage/*

Screenshot of the GUI

Using lsblk via SSH, I can see the SSD's, but in the GUI only /dev/sdb1 is shown

I don’t know how omv functions behind the GUI, but it seems to me that settings for file systems and shares, got removed or corrupted.

As it is now OMV is totally useless, as every share is gone.😢

I hope there is someone with knowledge, that can guide me getting my nas back to working order. 🤔

FYI

Found another thread in the forum, where a user updated OMV7 and the ZFS plugin was gone.

Followed the instructions…

Disabled backports

Reinstalled openmediavault-zfs

Went to zfs/pools and selected to search for and recover all found pools (forced)

Found and recovered my pool

Now everything’s working again, even the shared folders are accessible from windows! 😀

Maybe this will help someone else, with a similar problem.
