Hey all, I know somebody here has got to have info that may be of help. If |
| 2 |
I'm totally missing something obvious here feel free to beat me to a pulp - |
| 3 |
but anything is better than silence :) Since I didn't get any responses last |
| 4 |
time I'll try one more time. |

Hello Everyone, |
| 9 |
I feel like the answer here should be obvious, but either my google skills |
| 10 |
have deteriorated badly, I'm missing the obvious, or I've just run into a |
| 11 |
strange problem (which I doubt). |
| 12 |
|
| 13 |
I have a Gentoo install with the following filesystem layout (from fstab): |
| 14 |
|
| 15 |
/dev/sda2 /boot ext3 noatime 1 2 |
| 16 |
/dev/sda6 / jfs noatime 1 1 |
| 17 |
/dev/sda3 none swap sw 0 0 |
| 18 |
/dev/sda5 /var jfs noatime 0 2 |
| 19 |
/dev/sda7 /home jfs noatime 0 2 |
| 20 |
|
| 21 |
Things work fine under normal circumstances, however if the machine is |
| 22 |
powered off uncleanly (power button, power failure, etc) it refuses to boot. |
| 23 |
The problem seems to stem from the fact that the root partition does not get |
| 24 |
checked prior to mounting. I have the following grub stanza which boots the |
| 25 |
system. It includes the "ro" option which is supposed to tell the kernel to |
| 26 |
mount the root partition read-only at first to perform a fsck. |
| 27 |
|
| 28 |
title=Gentoo Linux 2.6.12-r6 |
| 29 |
root (hd0,1) |
| 30 |
kernel /kernel-genkernel-x86-2.6.12-gentoo-r6 root=/dev/ram0 init=/linuxrc |
| 31 |
ramdisk=8192 real_root=/dev/sda6 udev hda=ide-scsi hde=ide-scsi ro |
| 32 |
initrd /initramfs-genkernel-x86-2.6.12-gentoo-r6 |
| 33 |
|
| 34 |
When booting this it basicly starts udev, then tries to mount filesystems |
| 35 |
and says /dev/sda6 is not a valid partition and drops me into busybox. |
| 36 |
|
| 37 |
The way I'm able to recover this is to boot to the live CD, |
| 38 |
fsck.jfs/dev/sda6 and then reboot and the remaining filesystems fsck |
| 39 |
fine and the |
| 40 |
system boots. However, one thing I notice is that once / is unmounted |
| 41 |
unexpectedly, it cannot be mounted prior to an fsck (get errors from mount). |
| 42 |
This seems like a bit of a chicken & egg situation. |
| 43 |
|
| 44 |
I can't believe this is a unique problem I've stumbled upon - does anyone |
| 45 |
have either an obvious answer to this question or some examples of a working |
| 46 |
gentoo install using jfs as the root partition (please, no responses of |
| 47 |
"yeah, works fine for me" if you can resist). |
| 48 |
|
| 49 |
I'll happily provide more info as desired - but thought I'd start here. |
