Determining Which Physical Drive Matches Which Logical Device
I have a RAID-5 array with four SATA disks in it. Apparently, two are going
bad, so I want to replace them. But, I'm not sure which physical drives to
pull. Given the following:
cat /proc/mdstat
Personalities : [raid6] [raid5] [raid4]
md0 : active raid5 sda[0] sdd[3] sdc[2] sdb[1]
735351936 blocks level 5, 64k chunk, algorithm 2 [4/4] [UUUU]
Any suggestions?
