Failed HD in Raid0 - which drive failed?
I have a failed drive in a software raid-0 assembly. (Fedora release 10 (Cambridge))
I re-added the drive just in case the failure was only a glitch but it failed again a day later.
My raid device is called md0.
The 2 physical drives are sdb1 and sdc1.
When both drives are attached I get a msg that sdc1 has failed.
- Which drive is sdc?
I detached one drive, booted the machine and it now had only sdb in the array.
Aha, I thought. Let's now swap, detach the current drive and re-add the other one.
Again the system tells me that only sdb is attached.
In both cases the (half) array mounted fine and showed no problems other than a missing drive.
It would be too easy if one of 2 drives was completely dead.
When both disks are attached it identifies /dev/sdc1 as the failed disk.
Which disk is sdc?
Also, is there some way to test if the disk is really bad?
Thanks in advance,
I think, I figured out one possible way.
fdisk gives me an identifier for the actual physical disk:
