unable to boot Arch after pacman -Syu

After a pacman -Syu the system began the download of packages, but it couldn't install because it said pacman was locked or something. I went and tried logging out to login, where upon the screen blanked and was forced to manual reboot.

upon trying to recover journal got this error and now i'm in [ramfs /]#

JBD: recovery failed
Ext4 -fs (sda)3: error loading journal
mount: mounting /dev/disk/by-uuid/uuid# on /new_root failed: invalid arguement
ERROR: failed to mount the real root device
bailing out, you are on your own goodluck

/bin/sh: can't access tty: job control turned off

Searches haven't found anything specific to this. My grub looks fine, not sure where to look. Anyone know of a way o recover from this without having to re-install?

where you see uuid# - i didn't want to write the whole number in there

Maybe this could help:

Also, you don't need to hide the uuid, as it is not like an ip address . No one will hack your hard drive

Re: unable to boot Arch after pacman -Syu

Hi, wasn't hiding the uuid, just just didn't want to type it in...typing from an spire one can be a hassle ;

I saw that thread before and did try:

mount -t ext4 /dev/sda3/ /new_root     with no success

not sure how to do that from the live cd

login as root
root@archiso with the same command mount point /new_root does not exist - never ran into this kind of prblem before so my experience is limited

Re: unable to boot Arch after pacman -Syu

The drive bricked. Appears to be a problem with Seagate barracuda 7200.11 firmware. Anyone with that rev should upgrade before yours bricks

Re: unable to boot Arch after pacman -Syu

You don't say which Barracuda drive is affected nor list a relevant link. Either/both of those would be helpful.

Re: unable to boot Arch after pacman -Syu

Hey, I'm having this problem too! Fun stuff. I tried mounting from the cd, but I get  "unable to read superblock". Part of the cause may have been that during -Su my connection was cut off, and it stopped halfway. Definitely nothing physically wrong with the drive. I can mount my boot partition just fine. Oh, and the fallback doesn't work either. Any ideas how to finish the update? Me thinks that would fix it, but I have to mount it first...

Not sure if it's relevant, but I did suspend to disk with s2ram before waking it up and rebooting.

Boot the arch live cd, chroot into your install (remember to mount the boot partition first), and run pacman -Syu. More info is in [wiki]Change Root[/wiki].

Tried, I literally can't mount it at all. It's fixed though, in a way. I reinstalled Record time too, about 2 hours from cd to hulu. BAM!
