Sometimes it is mounted correctly, but sometimes it is mounted badly then I only see "Segmentation falt" when do "ls /home". Here is how I solve the problem: 1. Edit /etc/fstab Move the next line /dev/hda7 /home reiserfs noatime,notail 0 1 to the end of the file /etc/fstab, below /proc and /dev/shm 2. Edit /etc/init.d/localmount mount -av #mount -at nocoda,nonfs,noproc,noncpfs,nosmbfs,noshm >/dev/null Without doing the above things, even reemerging reisfsprogs did not help me. Reproducible: Sometimes Steps to Reproduce: 1. In /etc/fstab put the line of /home above the lines of /proc and /dev/shm 2. Use the default /etc/init.d/localmount 3. Reboot machine Actual Results: The problem was resolved, but I dont understand why it was. Expected Results: Maybe /etc/init.d/localmount should be modified so that reiserfs partitions are to be mounted after mounting of /proc and /dev/shm. The problem did not happen before Gentoo 1.4 vapier@gentoo.org 2003-09-19 00:19:47 0000 the simple fact that a `ls` operation *segfaulted* should indicate to you that *something* *just aint right* ;) did you review `dmesg` to see if anything useful came up ? what happens if you `mount -o remount /home` when `ls` is segfaulting ? what kernel are you running ? what is the output of `emerge info` ? did you upgrade from 1.2 to 1.4 ? mholzer@gentoo.org 2003-09-21 03:30:23 0000 run #revdep-rebuild from gentoolkit vo.chi.cong@is.titech.ac.jp 2003-09-21 05:41:18 0000 root # revdep-rebuild Checking reverse dependencies...

Both baselayout and gentoo-sources have been updated since the bug received attention. Can this still be reproduced? Please reopen this bug if the problem persists. znmeb@aracnet.com 2004-04-06 20:20:36 0000 I am experiencing a similar phenomenon with 2004.0, recently synced. I have two reiser partitions, /dev/hda9 and /dev/hda10. Here are the lines in /etc/fstab for them: /dev/hda10 /mnt/hda10 resierfs defaults 0 0 /dev/hda9 /mnt/hda9 resierfs defaults 0 0 Yes, the mount points exist. They are first in my /etc/fstab; I haven't tried moving them to the end, but I'm about to try that. Meanwhile there are two "symptoms": 1. "vim" shows the "reiserfs" in red, as though it's trying to warn me about something. 2. The filesystems are not mounted after a reboot, and if I do "mount -a" I get DreamTimeGentoo root # mount -a mount: fs type resierfs not supported by kernel mount: fs type resierfs not supported by kernel DreamTimeGentoo root # Yes, I checked the kernel config and "reiserfs" is there. What's really peculiar is that I can manually mount them: DreamTimeGentoo root # mount /dev/hda9 /mnt/hda9 DreamTimeGentoo root # mount /dev/hda10 /mnt/hda10 DreamTimeGentoo root # df -k Filesystem 1K-blocks Used Available Use% Mounted on /dev/hda7 11203068 7342452 3291516 70% / /dev/hda7 11203068 7342452 3291516 70% / /dev/hda8 8254240 5782716 2136092 74% /mnt/hda8 none 224792 0 224792 0% /dev/shm /dev/hda9 4000024 1459128 2540896 37% /mnt/hda9 /dev/hda10 3092380 1108924 1983456 36% /mnt/hda10 Could this (and the fact that "/" appears to be mounted twice) have something to do with the fact that I don't have "/boot" as a separate partition, but it is instead a directory in the /dev/hda7 partition, which is ext2? Please let me know if I should file this as a separate bug. This one is the closest I could find to my symptoms.
