    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....

    Install as always, only select ReiserFS instead of ext2...

    I cheated and used Mandrake 8's Diskdrake to divide my harddrive into pieces, as it is easier that using the Debian one.

    and PRESTO, you have a ReiserFS based system... you could also goto www.linuxnewbie,org and search the "How I did" forum where a guy named Bradmont did a how-to, only without the bootdisc set.

    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.

    Hi,

    You only need a seperate /boot partition if you intend to use lilo whilst mount the root partition with tails on. Since you use lilo without a seperate /boot partition I assume you mount the the notails options.

    Using reiserfs with tails means the files are store more compactly, but gives lilo some problems when trying to read the kernel image. Tails also need a slight overhead, making notails partitions slightly faster.

    Either way using grub is generally a better option being a vastly more capable boot manager, making system recovery much simpler.

    Only one big partition. (And some extra /space needed then I converted from the ext2 fs)

    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'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.

    Well, I've had several freezes in the last couple of days. The first was when upgrading to kernel 2.4.7 (well, actually 2.4.5-ac-something), when trying to use my USB printer (an Epson 880). Just typing 'cat /dev/usb/lp0' as a user would make the kernel freeze. 2.4.2 still works, so it's probably not hardware.
    Then I upgraded to Woody, and alsa 0.9, and then the alsa-modules would freeze my computer. I downgraded alsa, so that's ok now, but I still can't get my printer working.

    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

    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.

    Reiserfs is designed specifically to avoid filesystem corruption when not unmounted propally. If these problems persist, contact the reiser team, they are very good about sorting out peoples problems.

    If we're sharing bad experiences with ReiserFS, I may as well share mine. First, I user ReiserFS on mutiple boxes, / and all. One of the features of ReiserFS is that the filesystem can be updated to the latest ReiserFS version. The problem with that is that it breaks backwards compatiblity. Currently I'm running 2.4.5. Last night I decided to try to switch from Lilo to Grub. Well, I goofed and couldn't boot Debian again, but I got the Windows entry right. So I stuck in the digitaltux rescue disk. rescue root=/dev/sda1 single, etc...imagine my suprise when I got a Kernel Panic: Couldn't mount root file system. I tried manualy mounting the drive from the install disks, the Linuxcare BBC, etc. but it just wasn't going to work.

    Thankfully, before rebooting I had created a loadlin archive with my current kernel and copied it to my Windows partition. (using mkrboot) Well, this would have worked fine if Windows ME had a pure DOS mode. So I had find a Win98 SE boot disk (I keep an image of one on my website along with rawrite2, just in case.) After booting from that, a simple loadlin linux root=/dev/sda1 rw single got me back up and running.

    Moral of the stroy: Make your own linux rescue disk for every kernel you run. (man mkrboot is rather useful)

    So I'm back to lilo now. Will try grub another day. 🙂

    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.

    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.

    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.

    /boot is still ext2

    All of this with grub. Grub is nice if you intend to use reiserFS for /boot too.
