vm-103-disk-1.raw is the disk from the old system.
When I try to start it from that disk (after adding it to fresh installation):
I get error: Unknown filesystem
The original installation is about 1 year old was there any change that would block it from using older fs? Any way I could install old HAOS to use the old drive and make backup?
I noticed that the older installation has drives created in opposite order UEFI drive and then System
-rw-r----- 1 root root 4.0M Jun 8 2025 vm-103-disk-0.raw
-rw-r----- 1 root root 32G Sep 21 14:12 vm-103-disk-1.raw
I tried to copy vm setup and just use those drives but the VM does not start then does not even give any output to console saying graphic output not started.
Hi, are you using different filesystems for your old and new Proxmox setup?
I had a similar problem coming from a ZFS setup and wanted to restore on ext4
But I also tried to mount this drive under debian VM but it does not see any file system there

My HAOS disk was broken when the supervisor went down
In case somebody find them self in this situation I think I am on a good route to restore it.
I used this to recover original partitions using vm with mounted original disk:
testdisk /dev/sdb
they were not in good state to use on new installation but they had automated backups:
supervisor/backup/automatic_backup_2026_9_2_2026-09-19_05.12_08002636.tar
encrypted encription key for them is found in:
supervisor/homeassistant/.storage/backup
Looks like I will be able to recover everything so happy ending.
Lesson again - do backup - make sure you can recover them!
