Well, initially? no idea. This is the second time that the repair 
failed, so the first one may not have been too kind to the system. The 
fs still mounts fine (or did before this particular failed repair), but 
has random file corruption (pieces of files get replaced with other 
junk). Most of the time without any XFS_CORRUPTION errors showing up in 
dmesg (though they did appear a few times in the past).
