I have big trouble with my OMV now. Hope someone can help.
I tried to upgrade my OMV 5.6.xx to OMV 6. I checked the plugins (omvextra and unionfs, said will be supported) then started with omv-update.
omv-update seemed to end with no errors (Maybe I missed some message). Then when I ran omv-release-upgrade, it terminated due to some source.list error.
I then noticed that I once manually changed source.list and source.list.d/openmediavault-kernel-backports.list, omvextras.list and os-security.list before, to get a faster connection.
It seems some apt source not updated from buster to bullseye, and caused the error.
After the upgrade terminated abnormally, I tried reverse sources to debian and omv default. but when I tried omv-update or omv-release-upgrade again. It said no command found.
I also tried apt update and upgrade. Apt upgrade failed due to some dependency issue.
Then I did the most stupid thing. I reboot the system. After the system reboot, everything in the system crashes.
No ip network (ip address command only shows loopback and mac interface), so no way to apt update or install
no files show in disk in /srv/dev-disk.... , Hope my files are still there. they just didn't show up.
cannot run omv-firstaid (command not found)
I tried rebooting to linux recovery mode and normal mode. But didn't find a way to recover it.
one good thing is that I run omv on promox virtual machine so that I can still access the system via console.
I really regret for what I have done.
I have 70T data stored. It will be a disaster if they can not be recoverd.
