Dave,
Thanks for the feedback. Unfortunately that didn't solve my problem.
Here's specifics of my situation:
smartctl is reporting bad sectors on partition /dev/sde1, so I wanted to
find what files are affected.
I used dd to read a series of sectors bracketing the sector reported by
smartctl to /dev/null while reporting sector numbers. I took note of the
first sector to report read errors, 1084296736. Then I calculated the JFS
block number as ( SectorNum - PartitionStartSector ) * 512 / 4096. The
result I got was ( 1084296736 - 63 ) * 512 / 4096 = 135537084.
Following are the results of my jfs_debugfs session for this JFS block:

I was getting the same kind of responses if I used -1635135392 as the inode
of interest instead of 1635135392. Anyone got more advice?
Craig.
