View Full Version : [ubuntu] "Gave up waiting for root" with LVM on LUKS

March 3rd, 2013, 01:32 AM
Hello. I have a laptop here that has an LVM on LUKS setup. I had cause to regenerate the initramfs from a Live CD and chroot, and this apparently harmed the GRUB line that boots the system.

I now get a BusyBox shell on every boot after the kernel fails to open the root device. I can manually open the device from here with cryptsetup, exit the shell, and the boot continues happily. *After* I do this, I see a passphrase prompt but it's not necessary to fill out and doesn't take any input (presumably because the device is already unlocked).

I would really like this to work again without requiring the full cryptsetup command and BusyBox cycle. What is the standard GRUB line required?

Right now I have

linux /vmlinuz_something_something root=/dev/mapper/ubuntu-root ro verbose vga=z

I've tried lots of different things, including specifying a cryptdevice and a rootdelay. Would really like help on this.

It seems that anyone else who has had this problem has assumed their system was nuked and did a full reinstall. That sounds awfully extreme to me. I just need to know, based on Ubuntu's configuration, how do I do this? I can do it fine on Arch boxes, but Ubuntu seems to do things differently.

I have exactly the same problem now. Any news on this?
