 |
|
Okay, I've had a couple crashes recently (still trying to track it down) -- but I'm curious about the following.
My boot partition is ext2 which contains the kernel. My root partition is jfs, and support for jfs is compiled into the kernel.
When the machine crashes, upon reboot, the machine fails to boot. It errors out on unable to mount root partition... I boot off a CD, fsck the root partition, reboot and all is fine.
My question is, shouldnt the system be smart enough to run the fsck process itself? Also, since its a journaling file system, it shouldnt require an fsck to boot properly. So, I must have done something wrong..
Edit: More info...
I use genkernel, and notice after I manually fsck the drive, upon bootup it does fsck the drive, but only much later into the bootup process. When the drive is dirty, it never makes it that far.
Here is my grub config:
| Code: |
# For booting GNU/Linux
title Gentoo Linux (kernel-2.6.8.1-mm2)
root (hd0,0)
kernel /kernel-2.6.8.1-mm4 root=/dev/ram0 init=/linuxrc ramdisk=8192 real_root=/dev/sda3
initrd /initrd-2.6.8.1-mm4
|
And the fstab
| Code: |
# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
/dev/sda1 /boot ext2 noauto,noatime 1 1
/dev/sda3 / jfs noatime 0 0
/dev/sdb1 /mnt/space reiser4 noatime 0 0
/dev/sda2 none swap sw 0 0

You might want to read the following:
| man fstab wrote: | | Code: | The sixth field, (fs_passno), is used by the fsck(8) program to determine the order in
which filesystem checks are done at reboot time. The root filesystem should be speci-
fied with a fs_passno of 1, and other filesystems should have a fs_passno of 2.
Filesystems within a drive will be checked sequentially, but filesystems on different
drives will be checked at the same time to utilize parallelism available in the hard-
ware. If the sixth field is not present or zero, a value of zero is returned and fsck
will assume that the filesystem does not need to be checked. |
|
Then adjust your fstab as follows:
| Code: | # NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
/dev/sda1 /boot ext2 noauto,noatime 1 1
/dev/sda3 / jfs noatime 0 2
/dev/sdb1 /mnt/space reiser4 noatime 0 0
/dev/sda2 none swap sw 0 0 |
If you have another crash, then this should allow the fsck to proceed at startup...

Hello ekool,
My guess is that the unknown source of your crash might be causing the corruption of your root partition, as opposed to the crash itself corrupting it. I bring this up because if your HD is being messed up by something, then it's possible that the files needed to launch and/or run the fsck are lost until the file system is straightened out by the fsck on your CD.
My other guess is that you've got a ticking time bomb waiting to take out your data permanently. Random crashes with corruption of your HD does not sound good to me at all.
Best regards  |
