Yes, it's a RAID 5 array that failed pretty bad due to multiple reboots
of the machine. Some disks failed and at some point, the RAID card did
stopped to detect some of the disks, or failed to assemble the RAID
array correctly. 3ware (LSI) issued a fix that allowed to start the
array in degraded mode, but the xfs filesystem seemed in a pretty bad
shape at that point. xfs_repair was failing right at the beginning and I
had to xfs_repair -L. Then xfs_repair was hanging forever. It's only
today, by using -P, that I got it to complete.

No I did not.

There are tons of gigs of files in lost+found but I can't really sort
them and figure out which one is which at this point...
