I use Fedora Core 2, the XFS partrition works well in half a year.
the sda is a disk array in RAID 5, using 3ware 9500 SATA RAID controller.
In Mar 13, the array degraded. And after rebooting the system, the XFS
partrition can not be mounted.
I tried mount it read-only, xfs_repair it but all failed.
the data in this partrition is very important, and i have no backup.
if i can mount it read-only, or fix the superblock, that will be very
very fortunate.
yours,
Jasper Ji

Hi,
Looks like you are having problems with your blockdevices.. Did you change
something?
New disks?
Switched controller?
Installed new kernel?
Submitting output from "dmesg" and "fdisk -l" could help a lot.
