Broken initramfs

[Guest]

I just installed onto LUKS-encrypted LVM on a GPT table. I can't figure out how to correct initramfs so it will boot everything up. I already reinstalled lvm2 and cryptsetup using a live CD. update-initramfs does nothing. This is the message I'm getting right now:

Gave up waiting for root device. Common problems:
– Boot args (cat /proc/cmdline)
– Check rootdelay= (did the system wait long enough?)
– Check root= (did the system wait for the right device?)
–Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/mapper/vg1-root does not exist. Dropping to a shell!

BusyBox v1.20.2 (Ubuntu 1:1.20.0-8ubuntu1) built-in shell (ash)
Enter 'help' for a list of built-in commands.

(initramfs) _

I'm only able to get to this initramfs shell, so anything I do is through the live CD. Help?

I have the same issue, also with a LUKS encrypted LVM GTP setup. I was able to boot an old kernel and initramfs from grub and will backup that configuration now. I suggest you try the same and I'd be very happy if you left a message here if you find a permanent solution - I will do the same.

Henrik, I unfortunately don't have any old kernels to boot into since this was a new installation. I just installed Arch (successfully) onto my main box using this same setup, but Arch's initramfs files are quite a bit different from K/ubuntu's. I will definitely post back if I figure it out though.

So I fixed my issue. I actually reinstalled and copied etc and home from a backup to get rid of a big swap partition in the setup. I replaced fstab but missed replacing crypttab causing disk decryption to be broken (wrong device name and uuid in crypttab). Have you checked whether or not crypttab is correct?
