Hi, I want to be able to identify the exact device creating truble for my RAID-5 backed LVM. The issue: I have a 4 disc RAID-5 array that holds my /home asan LVM volume group. Recently, I am getting errors like: Buffer I/O error on device dm-7, logical block 10526729 So, I do: # dmsetup table /dev/dm-7 0 251658240 linear 9:127 2048 Major 9, Minor 127 is my MD device "/dev/md127" My /dev/md127 is made up of 4 disk partitions. I want to know on what disk does "logical block 10526729" lie so that I can identify the culprit and replace that disk. Any ideas?
