Can you please run xfs_check on the filesystem after this has happened.
I suspect you may have found a hole in the endian conversion code in
XFS. Doing the copy into the filesystem over NFS is probably
generating more fragmentation and hence more complex free space
structures than doing it locally.
I attach the output of xfs_check. The filesystem is fragmented a lot -
there is lot quite big (300-500 MB) files and many many office/CAD
documents with few MB each. If you want I can do some more tests but
only till sunday morning - then I have to format it to ext3 :-(
