XFS corruption with rsync

I'"ve seen this error showing up on the list previously: while
rsync'ing a large volume (66 TB copied to a 114 TB filesystem), I've got
this error showing up:

Rsync logs says that "structure needs cleaning". After running
xfs_repair, there's a few files making reference to a free block.

This machine has had serious filesystem failure previously, but the
RAID array and filesystem have been rebuild from the ground up, so it
should be OK; however I'd like to be really sure there's no hidden
hardware glitch waiting to bite us again...
