It looks like entire sections of the partition are trashed. Could one or more of the disks in the RAID array be having problems? I guess RAID-5 should be protecting you from a single disk failure, but the problem looks like something affecting large sections of the raid array. > Is there anything I can do to recover the data?

If you are confident that you can rule out a problem in the RAID array, I guess there could be an LVM problem, but I'm not aware of any in the 2.6.8.2 kernel. I really don't of any jfs problems that would explain such widespread errors after such a long time of stability. I wish I has something more positive to tell you.
