Just want to ask - XFS repair or XFS check. Last time I tried it on
linux I got a out of memory error (with 24GB memory available).
AFAIK it does need a really large memory to check big partitions with
lots of files in it.
Not that we need it much, but in case of error it is important.
So far I got best recovery on broken partitions with ext3 fs, not with
reiser neither XFS.
