In a degraded array (4 disks: sdb,sdc,sdd,sde in RAID 5). One of my disks failed (sdc). Is there an easy way to figure out which PHYSICAL disk that is? I have always just unplugged the sata cables one at a time to map it, but it occurs to me that the drives may be enumerated in order (SATA port0 is sda, SATA port 1 is sdb, etc...) Or, does the OS have access to serial numbers, etc...? I have to guide someone through a drive replacement on the phone, and it would be great if I could tell them exactly which drive to swap out...
