We have a Linux server running with Software RAID1. We see some issues in
/var/log/messages like: unreadable sector. I want to perform a complete
fsck on the drive to get some more information, but a
fsck /dev/md0 brings a clean due to the Software RAID layer in between. How can I check the real hard drive? Do I need to disassemble the whole RAID? How do I deal with the inconsistency in the partition due to the additional Software RAID header?
Does anyone have a good idea for this?
