I have a Ubuntu server with 9 backplanes. Each backplane can have 5 hard drives (45 in total). I plugged in 45 hard drives, and a quick
ls /dev/sd* shows only 43 drives (other than the boot drive). Is there a quick way to find out which two hard drives are bust?
The back planes are wired in a special order, so that if all the hard drives were working, I know exactly which slot is sdb, sdc and so on. I can list the serial numbers of the hard drives using
smartctl -a /dev/sdb | grep Serial for each drive, and then match them physically by looking at the drives. But I was hoping that there will be an easy way to find it out!
