    Reiser-FS on / ?
    Contributed by Anonymous on Monday, July 30 @ 19:32:35 BST

    Ask Debianplanet
    I'm getting tired of those e2fscks after my kernel has decided to freeze again.

    Has anyone of you tried Reiser-FS on / (as in root)? I would like to use it next time i set up a box but it feels kind of scary regarding its heavy presence in the kernel-changelogs....

    Works just fine for me, no probs for far.

    I have /boot as ext2 and / as ReiserFS (without notail)

    Works fine here. I have ReiserFS on all my filesystems except /boot (too lazy to learn grub). Just had to do some gymnastics as the installer does not support ReiserFS.

    I switched to reiserfs / a couple of months back, without any problems. I had a pretty small / partition, so I just made a new reiserfs partition and copied the contents over, and kept the old one around for a month in case I ran into trouble - which I didn't.

    I've been running Reiser-FS for a long time now, no problems. I used the unofficial Debian boot disks with Reiser-FS support. After that I upgraded to kernel 2.4.x, since it has more up-to-date reiserfs supprt.

    Since I run a small / partition is there any big advantage to running Reiser on it? I made /usr, /var, /opt, and /home as Reiser but left / and /tmp as ext2.

    My assumption at the time was that in case Reiser got fscked up I could still easily boot my machine w/o special boot disks. Maybe I'll have to reconsider this.

    I use ReiserFS for all of my partitions here at work. I am very pleased with it. It has never given me any trouble. I'll be putting my root and everything else on ReiserFS as soon as I upgrade my disc at home. Use it, it's wonderful.

    I run ReiserFS on all of my filesystems with lilo. However, I don't have a /boot partition. I havn't heard anything about needing grub... is this only if you have a /boot?

    I've been using Reiser-FS for all of my filesystems except /boot for a couple of months now, and it's worked great. I just copied my root partition over to home and made the switch then copied everything back. Did the same with home (to root), and it's worked great for me so far. It's excellent on a laptop because now I don't have to worry so much about lost files when my battery dies.

    I'm using it on my laptop for all the filesystems since 2.4.0. Works great. I did manage to screw things up badly one time, but was able to recover cleanly (user error - mine). The best two things I've done with my laptop (after wiping windows off it and installing linux) were reiserfs and grub.

    what the hell is a kernel freeze? (Score: 0)
    by Anonymous on Tuesday, July 31 @ 00:18:24 BST

    I've only been using GNU/Linux for four years but the only thing I've ever seen bring the kernel *down* is $ shutdown -h now. If your kernel is *freezing*, as you say, I would try to locate the cause rather than putting reiser-fs on a faulty system. If you are getting disk errors I would suspect a bad hard disk or disk controller.

    Possible procps bug with reiser-fs and 2.4.7 (Score: 2, Informative)

    There are very big issues around kernel 2.4.7, reiser-fs and some very, very wierd bugs with the /proc filesystem.

    Basically, stat()ing something in /proc may fail under certain circumstances, you can read the screams of pain on the
    Reiserfs mail archive.

    Be warned about this, it means things like top and ps will break!

    just search for xfs on debianplanet, I used the boot disks developed by zoltan et. al. This works great for me.

    xfs has some impressive features, and supports massive filesystems. check it at

    It looks like I may be the only one who has had problems... 🙁 I switched to reiserfs about two months ago on / (I only have one partition, so it is also my /boot, of course) and everything seemed to be going smoothly...

    Until one day I would get a kernel panic every time I untarred a file. I could create new tar files, copy files, etc. but any time I tried to untar something it would panic or freeze.

    I spent hours trying to diagnose the problem, assuming it was hardware. Well, it wasn't. I finally started screwing around with reiserfsck, and decided to do a 'reiserfsck --rebuild-tree', which took about two hours. After that everything was back to normal with no (known) data loss.

    I've also seen weird things after crashes like two files concatenated together and one time a file duplicated on top of another file. But those are crashes, so I guess some data loss is expected. It's the strage WAY in which the data was lost that creeps me out.

    Honestly, if I had to do it again, I'd stick with ext2, but it sounds like my experience is not the average one.

    Success on production ISP servers! (Score: 0)
    by Anonymous on Tuesday, July 31 @ 08:27:42 BST

    I've got two production servers with root devices running ReiserFS over raid5. I still have to have /boot on its own partition because grub doesn't read raid5 (yet). On a third non-raid server the entire root device is ReiserFS. We've had one of these servers running this way since late last year. The other since early this spring.

    I STRONGLY advocate use of ReiserFS. It is stable, fast, and as far as I can tell there's no trade-off over ext2. Its only competition are xfs and jfs.

    I've used ReiserFS on my laptop for all partitions except /boot since September 2000. Never had a single problem, and never lost any data. If you install from a Potato CD then it can be a bit fiddly to switch the root partition from ext2 to reiserfs.

    Started off with kernel 2.2.16 patched with reiserfs 3.5.24, and kept using the same patch with 2.2.{17,18pre21,19}. Even survived without a working fsck.reiserfs. Now I run 2.4.6, but the partitions still have the old reiserfs format.

    Summary: I'm another very satisfied customer.

    I'm using reiserfs on all partitions (usr, home, root) on my iBook and I have no separate boot partition.

    Because of that I had to tweak a little with things. I had to apply a patch to yaboot, to make it read kernels from reiserfs partitions.I also had to apply a patch to my kernel to make it able to use reiserfs at all, since reiserfs has just recently been ported to big-endian architectures.

    I don't know if others have this problem, but every time I compile a new kernel I have to apply this same patch to it, otherwise it'll crash when it boots.Don't know why...

    but apart from that, everything works fine.

    I'm especially pleased with the fact that I can turn off my computer anytime and I won't lose any data. That was impossible with ext2. I strongly recommend reiserfs to anyone.

    The patches I used and some guidelines can be found at

    ReiserFS has it's uses. But if you tend to access the filesystem to retrieve alot of static data, AND you use IDE, go for something else. That combo eats up all my processor time and demands more. If you look at the benchmarks that were done a while back, and look at the CPU utilization of ReiserFS/XFS vs. ext2 you will see what I am talking about.
