Sorry for the lack of response from us, we are a bit thin on the
ground at the moment, and there are going to be less of us around
for a couple of weeks.

All I can really recommend is getting the filesystems unmounted
and running xfs_repair on them. Also while the fs is idle and
after it is clean as far as repair is concerned, try running
xfs_fsr on it. We have seen some issues with fragmented files
causing problems - however, the defragmenter seems to have
issues running whilst nfs is active - hence run it without the
filesystem being used via nfs.
