Thanks for the info. I'm about to put in production a new mail server
(tomorrow) and I've switched from reiserfs to jfs for the /home
partition. That was because recently I've discovered that some files
cannot be read due to a power failure:

  du: cannot access `marius/Maildir/cur/12152.gali:2,S': Permission denied
  gali:/home# ls -l "marius/Maildir/cur/"
  [..]

  ?--------- ? ?      ?         ?                ?
marius/Maildir/cur/12152.gali:2,S

I've read that 'jfs' is much stable and compared with xfs it doesn't
have the same performance but its a safer choice to avoid data
corruption at power failures + lower cpu consumption.

Although this bug report was about reiserfs, please drop us a short
message if there are any concerns about 'jfs' too.

Thanks a lot.
