 Posted: Tue Dec 14, 2004 1:11 pm Post subject: gentoo-dev-sources 2.6.9-r9 vs. r1: root volume not valid? |
 |
|
Hello,
I'm having a problem with the current gentoo-dev-sources (2.6.9-r9). Some days ago, I compiled 2.6.9-r1 from the sources on the LiveCD, using | Code: | | genkernel --udev all |
This kernel works still. My /etc/fstab is:
| Code: | /dev/hda1 /boot ext2 noatime 1 2
/dev/hda3 / reiserfs noatime 0 1
/dev/hda2 none swap sw 0 0
/dev/cdroms/cdrom0 /mnt/cdrom auto user,noauto,ro 0 0
/dev/fd0 /mnt/floppy auto user,noauto 0 0
# NOTE: The next line is critical for boot!
none /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)
# Adding the following line to /etc/fstab should take care of this:
none /dev/shm tmpfs nodev,nosuid,noexec 0 0
|
Now, I wanted to add IPTables to my kernel and upgrade to the newest code. I emerged 2.6.9-r9 and compiled with | Code: | | genkernel --menuconfig --udev all |
In menuconfig, I activated the options for IPTables as well as some other things. I did not deactivate anything except the wireless networking and speakup console (config diff below).
I generated a second entry in my grub.conf by copying and adapting the first one:
| Code: | # For booting GNU/Linux
title=Gentoo Linux 2.6.9-r1
root (hd0,0)
kernel /kernel-2.6.9-gentoo-r1 root=/dev/ram0 init=/linuxrc ramdisk=8192 real_root=/dev/hda3 video=vesafb:ywrap,mtrr,1024x768-16
initrd /initrd-2.6.9-gentoo-r1
# For booting GNU/Linux
title=Gentoo Linux 2.6.9-r9 (mit iptables)
root (hd0,0)
kernel /kernel-2.6.9-gentoo-r9 root=/dev/ram0 init=/linuxrc ramdisk=8192 real_root=/dev/hda3 video=vesafb:ywrap,mtrr,1024x768-16
initrd /initrd-2.6.9-gentoo-r9 |
Now, I can still boot from the first kernel, but the second one stops with this error:
| Code: | >> Determining root device
>> Block device /dev/hda3 is not a valid root device
>> The root block device is unspecified or not detected.
Please specify a device to boot, or "shell" for a shell.... |
Has anybody a clue what could be the problem?
My thoughts: Obviously, the partition is OK, since I can still boot from it with the old kernel. Same for the grub.conf entry. Have there been any relevant changes from 2.6.9-r1 to 2.6.9-r9? I could not see anything in the changelog.
I'm including a diff between the two kernel configs as genkernel created them. I can supply further info if necessary.
Cheers & thanks for any hint
Kaspar

how about you try with exactly the same .config ? the diff shows that you have changed quite a few filesystem/partition options and thats most likely to be the problem

OK, I have genkernel running now with the old config and will try again tomorrow (CET...)
Meanwhile, thanks!

Well, I am feeling a bit stupid. Compiled using the old config, the kernel boots perfectly. I suspect these changes to be the culprit:
| Code: | 1327,1328c1336,1339
< CONFIG_REISERFS_PROC_INFO=y
< # CONFIG_REISERFS_FS_XATTR is not set
---
> # CONFIG_REISERFS_PROC_INFO is not set
> CONFIG_REISERFS_FS_XATTR=y
> CONFIG_REISERFS_FS_POSIX_ACL=y
> # CONFIG_REISERFS_FS_SECURITY is not set
|
This would mean that the reiserfs driver with extended attributes compiled in cannot mount the (root) file system that was generated without those attributes. I'll have to read up on this, but it does seem strange.
Lessons learned: (1) Never change more than one thing at once in a working kernel config (2) Know what you're changing
dsd, thanks for your help!
