 Posted: Thu Jan 09, 2003 1:19 am Post subject: OOOPS! (help! Won't boot after update) |
 |
|
Hi..
I compiled a whole bunch of system upgrades today through emerge -u world (cant even remeber which they were., but one of them was binutils)
Anyway.. emerge warned me that I had config files in /etc that needed attention, but I accidentally rebooted before having a chance to take a look at them.
Now Linux doesnt boot anymore.. It complains it doesnt have permission to read /bin/rc, and cant find a lot of stuff in the sbin folder when init changes.
I'm obviously going to have to boot off of the livecd, mount my root partition and edit the approrpiate files in /etc.... But... Which ones are they, and what should I change them to?
GAAAH!
I'd appreciate any help!
Thanks,
Matt

the best way to fix this is go back here http://www.gentoo.org/doc/en/gentoo-x86-install.xml
and edit back all the files u edited while installing 
ie. /etc/conf.d/net (to restore ur settings for ur eth0)
no need to rc-update them |

Is it the case that filesystems cannot be mounted (corrupt /etc/fstab) or they are all mounted but binaries are corrupt?
What happens if you boot from install-CD, login, and fsck the partitions?
Failing all this, the previous suggestion is perhaps your only door!

When I boot up from a CD, and mount the partitions everything seems to work ok. From memory, this is the error screen I see when it finally stops:
| Code: |
INIT: Cannot execute "/sbin/agetty"
INIT: Cannot execute "/sbin/agetty"
INIT: Cannot execute "/sbin/agetty"
INIT: Cannot execute "/sbin/agetty"
Id "c1" respawning too fast: Disabled for 5 minutes.
INIT: Cannot execute "/sbin/agetty"
Id "c2" respawning too fast: Disabled for 5 minutes.
INIT: Cannot execute "/sbin/agetty"

INIT: Cannot execute "/sbin/agetty"
Id "c4" respawning too fast: Disabled for 5 minutes.
INIT: Cannot execute "/sbin/agetty"
Id "c5" respawning too fast: Disabled for 5 minutes.
No more processes left in this runlevel
|
and if I <Crtl><alt><del> I get:
| Code: |
INIT: Cannot excecute /bin/shutdown
|
There is more stuff above the agetty crap, but it goes by too fast for me to read it.
Any ideas what might be going on?

When you boot from CD, access to binaries will be from the CD not your filesystem, consequently your filesystems could be the problem, bad emerges or bad bootup, so, check these IN ORDER GIVEN:
1."Bad filesystems"
As I said earlier, which you still haven't done(!), perform an fsck. If you are not sure what to do, then boot off the CD, and "fsck -a /dev/xxxx" where "xxxx" is each of your partitions. Make sure each partition IS NOT mounted.
2. Check your root device is correctly specified in LILO and/or GRUB configuration files. If you are not sure what to do here, then post us your configuration files /etc/lilo.conf and /boot/grub/menu.lst and /boot/grub/grub.conf and the output of "cfdisk /dev/hda".
3."Emerges"
Re-emerge packages.

hehe after reinstalling three times, I think I finally figured out what I was doing wrong hehe. I forgot to add a symlink from grub.conf to menu.lst hehe.
I'm going to see if that fix works.

oh man..
I feel so embarrased now.
Soo much aggravation and work over somethin a silly as this.
It wasnt the symlink that was the problem. The problem was that I accidentally added the option "user" to my boot and root partitions in fstab.
Oh Well..
At least now it works. Time to recompile X. (wohoo, just what I want to do.)
Thanks for the help guys.

I realize this thread is a year old but I just wanted to thank you, Zarathustra[H], for your last post in this thread no matter how embarassing it was for you  because I did the exact same thing! A search in the forums revealed your thread and my problem was solved. |

After hours hours hours of googling, #gentoo-ing, doing random stuff on my own, and eventually signing up on this forum and searching for my error - this fixed it =) Soo thank you! And from now on I'll remember that adding "auto" to my root partition in /etc/fstab is a Bad Thing (tm)
Thanks!

I'm still having the same problem, however, I'm using an nfs root.
Could anyone please tell me if I have passed the wrong parameters in my fstab:
| Code: | # <fs> <mountpoint> <type> <opts> <dump/pass>
192.168.0.1:/mnt/data/xbox / nfs nolock,exec,rw,nfsvers=2 0 0
/dev/hda50 /mnt/fatx/E fatx defaults 0 0
/mnt/fatx/E/linuxswap none swap sw 0 0
/dev/cdroms/cdrom0 /mnt/cdrom iso9660 noauto,ro 0 0
# NOTE: The next line is critical for boot!
proc /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)
shm /dev/shm tmpfs nodev,nosuid,noexec 0 0

Thanks! |
