I have a problem whereby the SAN which was storing all my virtual machines developed a problem. I had to backup everything on the volume, delete it, recreate it and move everything back. During this, I think my VHDs became corrupted or developed problems. I have been trying to add them to new VMs in order to bring everything back online but am not having a lot of luck in doing so.
Hyper-V reports that one VHD is corrupt and doesn't seem to recognise the others. When I bring the server back online (this is my file server and has 8 disks) the drives show as offline in disk manager with blank grey spaces. When I try and bring them online they say "invalid". I can't bring the disks online or initialise them, leading me to believe they may be corrupt too.
Is there a way to recover from this? My backups are obviously not good.
