should give you the devices in your RAID1 array. For example, lets say they
are /dev/sda1 and /dev/sdb1
Now, if you run
you will get a lot of output about your system. Look for the disk section
with the failed /dev/sd device in it. For example, let's say /dev/sda1 is
the failed drive. When I do sudo lshw on my system, I end up with this disk
section relating to /dev/sda:
description: ATA Disk
physical id: 0
bus info: scsi at 0:0.0.0
logical name: /dev/sda
size: 298GiB (320GB)
capabilities: partitioned partitioned:dos
configuration: ansiversion=5 signature=000d9eb3
This should give you all the information you need to determine which
physical drive it is.
Hope this helps,
