 Posted: Mon Feb 05, 2007 3:45 pm Post subject: portage reiser partition not mounting [unsolved, using ext2] |
 |
|
Hi
I just installed my new gentoo system over a fakeraid(followed the wiki's howtos), and everything went fine, till I reboot'd my system. It seemed that it'd boot fine, then it failed mounting all partitions except root and swap. Here's my fstab:
| Code: |
# /etc/fstab: static file system information.
#
# noatime turns off atimes for increased performance (atimes normally aren't
# needed; notail increases performance of ReiserFS (at the expense of storage
# efficiency). It's safe to drop the noatime options if you want and to
# switch between notail / tail freely.
#
# The root filesystem should have a pass number of either 0 or 1.
# All other filesystems should have a pass number of 0 or greater than 1.
#
# See the manpage fstab(5) for more information.
#
# <fs> <mountpoint> <type> <opts> <dump/pass>
# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
/dev/mapper/sil_adbhabdeccbi1 /boot ext2 noatime 1 2
/dev/mapper/sil_adbhabdeccbi3 none swap sw 0 0
/dev/mapper/sil_adbhabdeccbi7 / ext3 noatime 0 1
/dev/mapper/sil_adbhabdeccbi5 /var ext2 noatime 0 2
/dev/mapper/sil_adbhabdeccbi6 /usr/portage reiserfs noatime,notail 0 2
#/dev/cdroms/cdrom0 /mnt/cdrom iso9660 noauto,ro 0 0
#/dev/fd0 /mnt/floppy auto noauto 0 0
# NOTE: The next line is critical for boot!
proc /proc proc defaults 0 0
# glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for
# POSIX shared memory (shm_open, shm_unlink).
# (tmpfs is a dynamically expandable/shrinkable ramdisk, and will
# use almost no memory if not populated with files)
shm /dev/shm tmpfs nodev,nosuid,noexec 0 0

I can't really understand dmesg | less output, but it says something about a Reiserfs error, then Reiserfs panic, like it wasn't able to find the device. Really weird.
In spite of that, i can login, and when i try to manually mount /usr/portage, it simply locks up, no error message, nothing. It even won't die if I "kill -9" it from another console.
I can, however, mount /var manually, but still, its functions are crippled, I cannot reboot or shutdown properly.
Sorry, I'm kinda in a hurry now, so I couldn't post the dmesg output.
Maybe it has something to do with the kernel I'm using? Its 2.6.19-r5 gentoo sources. I heard that 2.6.19 had some ext3 and reiserfs problems.
I don't believe it could be related to the fact that I'm using fakeraid, since the chrooted system works fine when I'm on LiveCD, and /dev/mapper shows correctly the partitions when I boot.
I'm pretty sure I didn't forget anything kernel related. As a matter of fact, I compiled it all as built-in modules.
Thanks in advance.
EDIT: SHORT STORY: /usr/portage isn't mounting. I'm on fakeraid, but that shouldn't be a problem, and other partitions (ext2 and ext3) are mounting fine. When I try to mount this reiserfs partition, i get a reiserfs panic message, followed by a segmentation fault error. I checked my kernel(2.6.19-r5), tried an older one, and still can't mount it. Just reiserfsck'd it, no corruptions. Still, the livecd mounts the partition just fine. I compiled everything as built-in, and checked all the option concerning reiserfs. I have no idea what's going on.

sounds like either the partition got botched or it was improporly formatted, what version of RieserFS are you useing v3 or v4?

3.6
But I can still mount it and use its contents if I use the LiveCD. Oh yeah, and I forgot to mention, I used --block-size 1024 while formating. Maybe I have to pass an option for it somewhere in fstab??
And well, there's the /var partition that won't mount while booting aswell. Maybe it's not a partition problem.. |

Okay, turns out I tried an older kernel and it also didn't work. But what I noticed is that if I remove /usr/portage partition out of my fstab, the system boots without errors. Then, if I try to manually mount that reiser partition, it says something like KERNEL bug, fs/reiserfs/print.c line bla bla bla error, then there's this debug output i suppose, saying CUT HERE --------------------- and the following lines I can't really understand.
The thing is, I can still mount it from the livecd, and it's not corrupted or something. The only thing different I did was to format it using --block-size 1024. But then again, I mount it from the livecd like I would mount anything, without any other options, and its perfectly fine.
When I try to mount from my newly installed gentoo system, it fails.
So what am I missing here?? I did emerge reiserfsprogs, I compiled all the reiser stuff available on kernel (as built-in modules), all other ext2 and ext3 partitions mount just fine... any ideas?? |

try fscking it from the system see what you get, It sounds like a prob with the kernel, you may wanna check your settings and recomp the kernel just to make sure too.

Okay, just ran a reiserfsck and guess what. Nothing. It's not corrupted.
Still, when I try to mount it, it gives me a "Segmentation Fault" error, after some lines of reiser panic etc etc.
What's going on here? I went through the kernel over and over and still can't tell whats missing. I compiled all reiserfs options as built-in... any ideas? |

Or just don't use reiserfs at all, especially for /usr/portage/ where ext2 with 1K-blocks is a much better approach.

I considered using ext2, but I thought reiser had a better perfomance with small files nonetheless.
so I guess I'll try using ext2, never thought reiserfs would do this to me  |

| Strange, I cp'd all the stuff in /usr/portage to another folder, then I formatted it to ext2fs and copied the stuff all over again, now it's working just fine. Maybe some reiserfs bug when using dmraid and mount a non-default blocksize partition? |
