You know, I've heard the same argument against reiserfs for ages, and using it on countless servers (both home and enterprise) for at least the past 5 years I've _never_ once encountered unrecoverable reiser filesystem errors pertaining to whatever kind of ungraceful/ugly reboots I've had to do. T

Sounds like you're reaching inode limitations or something, validate with 'sudo tune2fs -l /dev/sda1 | grep "Free inode"'. You can change wtih tune2fs as well, at least with ext2/3, really haven't worked much with ext4 to know. I still stick with reiser mostly, it's a killer filesystem. -mb
