    ReiserFS and GRUB
    Contributed by ghbrewster on Monday, September 03 @ 09:04:08 BST

    File Systems
    Hi, I've got a single / partition (no seperate /boot) which is ReiserFS, and I'm using GRUB. When I was using LILO, I had to mount it with "notail". Is this also true with GRUB, or am I safe without "notail" now? I would like to remove it if possible for better space efficiency.

    Also, on the topic of ReiserFS mount options, if I have a ReiserFS 3.5 partition and then mount it with the "conv" option to convert it to 3.6 format, should I continue to mount it with the conv option later, or does it just need to be mounted once with "conv"?

    DanielS: You don't need any special options for ReiserFS to work with GRUB; I'm using it now (since I haven't patched GRUB with the XFS patches yet). As for "conv", AFAIK you keep it on.

    If you are running out of space using tails will get a little more out of your hard disk, but be aware that using tails will slow down file access somewhat.

    At least on my computer it only needed to be done once...

    a) See you boot messages, stuff like this should be in there:

    >>reiserfs: checking transaction log (device 16:05) ...

    >>Using r5 hash to sort names

    >>reiserfs: using 3.5.x disk format

    >>ReiserFS version 3.6.25

    This means the filesystem is still 3.5 format, while the reiserfs version is 3.6.25

    b) notail means reiserfs won't store small files and tails of files directly in the tree (just put's a marker in there that points to where it's on the hd).

    LILO is said (I don't use it) to not be able to handle this. But if It Works For You(tm), I wouldn't change any mounting options 🙂

    About the conv mount option:

    It's a one time thing only, but i keep it in anyway so it get upgraded whenever a new version comes up 🙂

    I haven't tried GRUB but LILO _CAN_ work with
    reiserFS _without_ -notail option.

    Extracted from lilo (21.7.5, debian unstable package) manpage:

    "lilo is known to have problems with the reiserfs introduced with the 2.2.x kernels, unless the file system is mounted with the notail' option. This incompatibilty has been resolved with reiserfs 3.6.18 and lilo 21.6."

    Yes, the new version of lilo fixes it.
