Now I'm on the standard source tree: $ uname -r 2.6.17-gentoo-r7 $ eix xfsprogs Available versions: 2.7.3 2.7.11 ~2.8.10 Installed: 2.7.11 which may be a factor. The other thing I notice is that my filesystems are all under 50%, whereas your troublesome one was at 80%or so: $ df -m Filesystem 1M-blocks Used Available Use% Mounted on /dev/md/2 529 134 395 26% / /dev/md/0 129 10 120 8% /boot /dev/md/3 3911 32 3880 1% /tmp /dev/md/4 3911 175 3737 5% /var /dev/md/5 19537 3008 16530 16% /usr /dev/md/6 19537 2668 16870 14% /home /dev/md/7 104841 25682 79160 25% /data0 I might try writing a few big files to fill one of 'em up and see if it makes any difference!
