    Thanks for the heads up. Have to remember never to use ext3 for the
    root filesystem. That one would have been a royal pain to debug.

    Or use "mkfs.ext3 -I 128 /dev/sdXY" to format. :-/

    I have /reiserfs/ on all filesystems of this machine here as well as on my
    laptop, and /xfs/ for all filesystems on my dual Opteron machine. Works
    like a charm.

    Apart from that /ext3/ has data journaling alongside the metadata
    journaling, I really don't understand why people so cling on to /ext3./

    In fact, I've seen far more problems with /ext2/ and /ext3/ on other
    people's machines than with /reiserfs/ or /xfs/ on mine. Both filesystems
    have already been stable for many years, especially /xfs./

    Alternatively, you could use LILO and bypass the GRUB problem. LILO doesn't
    read a filesystem, it heads straight for a logical block address.

    Your mileage may vary... ;-)

    That should work, as long as none of the other ext3 tools assume you are using at
    least 256 byte inodes.

    If I'm reading https://qa.mandriva.com/show_bug.cgi?id=38054 correctly, the
    version of grub supplied by Mandriva with 2008.1, has been patched to handle
    the 256 byte inodes, so the problem should only present itself, if you're trying
    to use an unpatched version of grub.

    The changelog for grub includes ...
    + Revision: 163119
    - handle ext3 256 bytes inode, which is the default

    If you're installing 2008.1, on an ext3 / (or /boot, if seperate) filesystem,
    you must use the 2008.1 version of grub, not the version from an earliar version,
    or another distro. Not as big of a problem, as I originally thought, which
    explains why I haven't seen anyone complaining about it.

    If you play with several different installations, you tend to pick the
    default.

    Bit of a maintenance headache to maintain lilo file after kernel
    updates in a multi-distro/multi-release setup.

    You can let the distribution update it's /boot/grub/menu.lst
    and the master menu.lst still boots the distribution's menu.lst

    Snippet example follows:

    title /2007_1 Mandriva Linux release 2007.1 (Official)
    root (hd0,10)
    configfile /boot/grub/menu.lst

    title /kubu7 Ubuntu 7.10
    root (hd0,12)
    configfile /boot/grub/menu.lst

    And I have yet to run into problems with ext3 on mine.

    Yes, best reason to use lilo. /boot/grub gets AFU, you can not boot
    any install.
    lilo's feature, has save me more than once in the past.


    I did notice grub 2 was in the contrib mirror.

    Hope so, all my ext3 partitions are created with 128 inodes.
    I was just about to split a 38 gig partition in half when I saw the article.

    Well, thanks for the research. I was about to install grub2 from contrib.

    I figured there would be the rub for the power user running a
    multi-distro installation. I tend to format the partition before
    booting the new distribution install cd.

    Yes, I wondered how we got through the 2008.1 install and yet had the
    256 byte tools installed without grub2.
