Well I suffered from the 2.6.17 endian bug and had fun with dis- and re-
appearing folders upon xfs_repair and mount runs.
After all the 'only' thing I lost from my 600+gb volume are one or two
mailing list folders and most of my inbox (for which I've backups).
Seems to only affect folders which were open at the wrong moment.

Now I reformated the whole volume and restore the data from other
disks.
