 |
|
Hi all folks,
For unknown reason my Gentoo 1.4 box can't start after running 'emerge -u world' Login as ROOT does not need root-password (key in root-password popup invalid password) and can't login as USER.
Incidentally Fail-Safe can be started
cat /etc/fstab found following difference.
ReiserFS changed to xfs;
/dev/ROOT / xfs noatime 0 0
following line being added;
none /dev/shm tmpfs defaults 0 0
Can I delete above line and change 'xfs' back to 'reiserfs' to fix starting problem?
# cat /etc/passwd
root:x:0,0:root:root:/bin/bash
...
...
Operator:x:11:0:operator:/root:/bin/bash
(USER/satimis not found there)
How to restore 'root-password' and re-add USER. Whether;
# /etc/passwd passwd
and
# /etc/passwd useradd
can solve my problem.
This test box without backup therefore I have to taking precaution on each step made.
TIA
B.R.

I assume that that is not the only thing that has changed in your fstab. /dev/ROOT does not exist you should replace it with for example /dev/hda1. Same thing for /dev/BOOT and /dev/SWAP.

Change a password with passwd <username> as root.
Next time when you do update world when it says you need to update some config files, do not just say -5 to automerge the changes. because then it replaces the config files with the default ones. |

Hi,
Thanks for your advice.
Edited /etc/fstab as per advice.
Rebooted the PC from xterm window on 'Fail Safe'
Still failed to start Gentoo with following warning;
Warning...fsck, reiserfs for device /dev/Root exited with signal 6
Filesystem couldn't be fixed.
This time 'Fail Safe' did not start
# cat /etc/fstab
.....
# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
/dev/BOOT /boot ext2 noauto,noatime 1 2
/dev/ROOT / reiserfs noatime 0 1
/dev/SWAP 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
# Adding the following line to /etc/fstab should take care of this:
#none /dev/shm tmpfs defaults 0 0
I commented out the last line. This time I was not allowed to make any change to /etc/fstab
Login as ROOT without password OK
Login as ROOT with root-password keyed in - Failed, invalid password
Soft-reboot failed and I have to press the reset button to reboot Gentoo box.

Noted with thanks
IIRC during 'emerge -u world'
it did not ask for any input.
What is '-5' representing for
Kindly advise. TIA

You still have the /dev/boot /root and /swap references in your fstab. You should change these to /dev/hda1 for /dev/boot, /dev/hda2 for /dev/swap and /dev/hda3 for /dev/root (if you installed gentoo on /dev/hda and followed the installation guide ofcourse).
| Code: |
/dev/hda1 /boot ext2 noauto,noatime 1 2
/dev/hda3 / reiserfs noatime 0 1
/dev/hda2 none swap sw 0 0

Hi,
Thanks for your advice.
Now I could not start 'Fail Safe' the second time. I think that I have to use CD1 to start the Gentoo box and;
mount /dev/hda3 /mnt/gentoo
nano -w /mnt/gentoo/etc/fstab
Last time I made mistake on editing /etc/fstab. Before editing, /etc/fstab looked as follows;
# <fs> <mountpoint> <type> <opts> <dump/pass>
# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
/dev/BOOT /boot ext2 noauto,noatime 1 1
/dev/ROOT / xfs noatime 0 0
/dev/SWAP 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
# Adding the following line to /etc/fstab should take care of this:
none /dev/shm tmpfs defaults 0 0
*********
To avoid further mistake, kindly advise whether I should edit /etc/fstab as follows;
/dev/hda1 /boot ext2 noauto,noatime 1 1
/dev/hda3 / reiserfs noatime 0 0
/dev/hda2 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
# Adding the following line to /etc/fstab should take care of this:
none /dev/shm tmpfs defaults 0 0
*************
Shall I comment out the last line
'none /dev/shm tmpfs defaults 0 0'
TIA

Hi,
Thanks for your advice.
My immediate problems are;
1) I could not start 'Fail Safe' again
2) I booted up the Gentoo box with CD1 but could not mout
cdimage # mount -t reiserfs /dev/hda3 /mnt/gentoo
/dev/hda3 no such file or directory
I tried /ext2/ext3/xfs
with same result
B.R.

This is the correct /etc/fstab (including the last line) to use -if- you have installed Gentoo on /dev/hda and paritioned it using the install guide.
But your last message tells me you didn't, or did something wrong
| Quote: |
cdimage # mount -t reiserfs /dev/hda3 /mnt/gentoo
/dev/hda3 no such file or directory
|
Check (using fdisk) if the partition really exists.
and then 'p' to print the partition table.
Which should look something like this
| Code: |
Disk /dev/hda: 30.0 GB, 30020272128 bytes
255 heads, 63 sectors/track, 3649 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/hda1 * 1 5 40131 83 Linux
/dev/hda2 6 68 506047+ 82 Linux swap
/dev/hda3 69 3649 28764382+ 83 Linux

| try running cfdisk to quickly see if your partitions are still in place, and if the drives are where you left them and such. it's a bit more friendly than fdisk |
