Well. I am not sure. And today I am away so I can test on my VM.
Well... I finally got a spare hdd to copy all the files from the raid array and about 10% into the copy, it seems like the raid drives are failing. The shared drive is offline and when I access the File Systems or Raid Management section in the OMV UI, I get "Communication Error"
I feel like a drive (or multiple) have failed. How can I confirm?
I've attached the output from the VM while it was trying to shutdown -- it's been a long time and still hasn't been able to shutdown.
EDIT: After rebooting OMV, it seemed startup but there's no RAID array in the RAID Management section. All the disks appear in the Disks section and they're all green in the SMART section.
