Try unmounting and remounting the filesystem, and see if the various

2.9.8.
Cheers, that got rid of most of it, there is still a slight
discrepency (50 extra fragments) which I can live with.
xfs_db used buffered IO on the block device, which is not coherent
with the filesystem. If you are using it on an active filesystem,
then running "echo 1> /proc/sys/vm/drop_caches" before you run
xfs_db should make it read from disk at least once....
Ah, that makes more sense, I'll give it a go.
Thanks
John
