Hi,

I've been trying to install the latest gentoo on an iBook dual usb (G3) 500 Mhz. After installing I didn't seem to get yabootconfig to work. Then I followed this tread: Installed Gentoo on TiBook IV! and let yabootconfig do it's thing. Then I rebooted and saw the boot-error. I also followed the same post to try and fix the filesystem, but that doesn't seem to help.
The exact error I am getting is:
Code:
*Mounting proc at /proc...      [ok]
*Mounting sysfs at /sys...      [ok]
can't create lock file /etc/mtab~890: Read-only file system (use -n flag
to override)      [!!]

*Mounting devpts at /dev/pts...      [ok]
*Starting devfsd...
/sbin/rc: line 280: /sbin/devfsd: no such file or directory      [!!]

*Activating (possible) swap...      [ok]
*Remounting root filesystem read-only (if necessary)...      [ok]
*Checking root filesystem...
ext2fs_check_if_mount: No such file or directory while determining whether /dev/hda8 is mounted.
fsck.ext3: No such file or directory while trying to open /dev/hda8
/dev/hda8:
The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternative superblock:
       e2fsck -b 8193 <device>

*Filesystem couldn't be fixed :(      [!!]

Give root password for maintenance
(or type Control-D for normal startup):

Does anybody have a clue to fix this? I already tried starting from top in the manual, but that didn't help.

You need to emerge the devfsd. This package manage devices for you.

Code:
emerge devfsd

or you can use udev (I prefer it).
Code:
emerge udev

maybe both are related to a missconfiguration in your /etc/fstab or that you dont have installed fs utils.

cheers

I get the same error here, here is my fstab file :
Quote:
# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
#/dev/BOOT /boot ext2 noauto,noatime 1 1
/dev/hda7 / ext3 defaults 1 1
/dev/hda5 /home ext3 noatime 0 0
/dev/hda6 none swap sw 0 0
/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!
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 defaults 0 0


udev and e2fsprogs are already emerged

ok, finally booting up after emerging devfsd. :D

During the boot process I still receive the error:
Code:
can't create lock file /etc/mtab~890: Read-only file system (use -n flag
to override)      [!!]


Does anybody know if this is a serious problem? Maybe a fix?

I ran into the same problem on an iBook G3. I installed fresh from the 2004.3 LiveCD and after rebooting was getting the same "corrupt superblock" error. This thread pointed me in the right direction.

It turns out that my kernel was compiled with options that were incompatible with udev, which is what a 2004.3 stage3 install appears to use. I suspect that the version of the Gentoo Handbook I was reading at the time didn't have updated kernel options listed yet. It appears that it has since been updated.

Instead of emerging devfsd, just recompile your kernel with the options shown at:
http://www.gentoo.org/doc/en/handbook/handbook-ppc.xml?part=1&chap=7#doc_chap3

Or if you use genkernel to build your kernel, run it with the --udev option.

For more in-depth information about configuring your system for udev, see this:
http://www.gentoo.org/doc/en/udev-guide.xml

Cyberfoxz, may I know which stage are you using? I'm using stage 3 and I don't have this problem eventough I fail to emerge udev ( due to no network during installation ). But it seems like stage 3 already did the udev merge for me.


p/s: The only problem with stage3 200.3 was I could not login due to PAM which was solved by emerging pam-login and shadow( later I get to a place where I can get internet)

After having read through the forums I tried solving it by emerging devfsd. I then rebooted and the problem still existed,, but the next time I rebooted, the error was gone. Probably something helped, but I am unsure of the fix.
