One server started showing the following error:

Nov 26 06:26:40 apple kernel: [212946.496906] sd 1:0:0:0: [sdb] Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK,SUGGEST_OK
Nov 26 06:26:40 apple kernel: [212946.496938] end_request: I/O error, dev sdb, sector 1642332223

Various search's in Google reveal this is a common sign of drive failure... luckily, in this case, this is a drive with no importance!
