Trying to recover raid pool

[nukem170]

I had openmediavault in a server that had a complete hardware failure. Disks were still fine. So I put them into a new machine and installed proxmox on a separate disk. Now on proxmox I can see the drives that I salvaged from previous machine. Is is possible to pass these disks to a brand new instance of an openmediavault while keeping the data?

As you can see below, sda, sdc, sdd, sde are the disks. It as a raid 5 setup. sdb is the main boot drive for the current machine with proxmox installation.

I don't see why not. Either by passing the storage controller they're connected to to the VM or using this: https://pve.proxmox.com/wiki/Passthrough_Physical_Disk_to_Virtual_Machine_(VM)

1. see what the system picked up at boot:
cat /proc/mdstat

IF you dont see anything: mdadm --assemble --scan -v
IF you see an md device (eg, md0) continue

2. file -sL /dev/md[x] from step 1. It will return a filesystem or lvm membership
IF LVM, vgscan && lvscan, repeat the file command on the resulting logical volume.
IF file system, you may proceed to mount it. you can add it to your fstab to make it permanent.

I wouldnt pass the disks directly to a vm, although you could do that too and follow the same steps above in the guest.
