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?
