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/" [..] drwx------ 2 marius users 360 2008-06-06 09:24 courierimapkeywords -rw-r--r-- 1 marius users 14686 2008-06-06 09:19 courierimapuiddb ?--------- ? ? ? ? ? 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.
