See "man xfs_db". It looks like the "blockget -v -b block-number"
provide useful info.
Thanks very much for this information: it is very helpful.
I do know the bytes and can figure out the sectors that are damaged. But I can't
figure out how that translates to the block number of an xfs filesystem. Is there any
reference for how to do this?
