Planning to reinstall omv

As I had a few screws up I'm considering to do a complete reinstall of omv 7 on a Pi5 with a Penta SATA HAT. All data should still sit on a zfs pool there and given my experience with ZFS on an ArchLinux system I think a reinstall will just be able to recognize the four SSD and be able import it. What I'm not sure about is how well the OMV installation is in finding (and not destroying!) existant sets.

Is it possible to start from scratch on the boot medium (SD-card) and have the zfs plugin recognize and import the existing pool?

Unfortunately on a newly installed system zfs cannot be installed :

What makes you think OMV can destroy data? OMV NEVER destroys data. Users do.

Not destroyed but unaccessible....

If I search for disable backports in these forums I find this thread. How do I disable backports?

Thanks. I could (force) import the pool

Now that is interesting. My old containers seem to be running but files is empty:

A bit of history for Soma

Raspberry PI5

With Penta SATA HAT

Four SSD

1. Configured with ZFS (as that is what I know from my Arch experience)
2. Connected to LAN
3. Attempt to connect to WAN with a ASIX based USB3 Ethernet cable
4. Nextcloud with Nginx Proxy Manager, Cryptomator, DAVx, Android, Linux, and Windows systems happily syncing, even got cookbooks
5. which worked for over a month or so
6. Had to move /var/lib/docker to the ZFS pool as overlay2 got out of control.
7. then ASIX Ethernet acted up and was recognized in half duplex only
8. where attempts from me to fix that ended up borking the OMV setup
9. Desaster recovery----
10. reinstalled OMV, ZFS, Compose
11. got it working to this point.

End of story sofar.

Maybe you can manually install packages and it will work but I'm not going to start testing zfs on rpis.

After the formidable suggestion to disable backports (on System/omv-extras) as well as enabling Docker repo (on that same page) I got partial functionality back.

I blame this whole thing on a ASIX USB/Ethernet adaptor using a partial supported but broken chipset AX88179B which "acted up" and was no longer doing full duplex auto negotiation to my Sunrise Internetbox router causing my nextcloud to fail. Troubleshooting this using internet suggestions was making things worse (horribily so) .

OMV (and Nextcloud) is for me a solid product but might lack a bit of docs on a Raspberry Pi/Penta HAT setup instructions.

Anyways I have my Lyrion Media Player back and might be able to revive my nginx proxied Nextcloud+Cryptomator with no data loss.

and dammit there it is: office.kingma.ch

single only problem. why is Serivces/compose/files empty?

where the containers are happily there:
