I just noticed a strange thing. I had my RAID 5 set up with five 2Tb drives and one 2TB drive set as a hot spare. Something happened and drive 1 went off line, but came back on line. Being a good little RAID array, it rebuilt on to the spare drive. However, now I can't find the old drive. It shows in the physical drive list as /dev/sdb, but no where else. I can see it when I do this:
Code
root@OMV:~# udevadm info --query=property --name=sdb

If I look at the array, I see this:

If the drive checks out, will I be able to add it back to the array? Right now, the drive isn't listed under the recover section to add it back as a Hot Spare.
Thanks,
Ted
