[solved] last kernel upgrade - dropped to recovery shell

Question

Hi there,
I just upgraded the kernel (=> 3.13.8-1-ARCH)
The boot process drop me to a recovery shell, with this message:
ERROR : device UUID=322d1dd7-5902-45e8-afe4-b5f912967b28 not found. Skipping fsck
ERROR : unable to find root device UUID=322d1dd7-5902-45e8-afe4-b5f912967b28
you are beeing dropped to a recovery shell
type 'exit' to try and continue booting
can't access tty, job control turned off
But, this UUID=322d1dd7-5902-45e8-afe4-b5f912967b28 correspond to none of my devices.
according to blkid
/dev/sda1: UUID="3fca6c29-1988-4ccd-9d84-dec5b44ffe80" TYPE="ext4"
/dev/sda2: UUID="f3fff5f5-b041-46e5-8749-01143684eb21" TYPE="crypto_LUKS"
The system is on a lvm, encrypted with dm_crypt.
I tried to correct manually the UUID of sda1 in /boot/grub/grub.cfg from a live usb, despite it is said to not edit manually the file. But it did not fix the problem.

Answer 1

I didn't read the trouble shooting section on your first link.
The wiki says :
- To not panic. I'm good for the first advice: I don't panic ;-)
- To boot from the Arch installer.
So I downloaded the Arch installer on a usbcard and booted it on.
- Apply # cryptsetup open --type luks /dev/mapper/MyStorage-rootvol on each lv.
Because I don't remember the designations of lvs, I tryed variations of
# cryptsetup open --type luks /dev/mapper/MyStorage-rootvol /dev/sda2
It keeps telling me /dev/mapper/<designation> doesn't exist or access denied.
Because it's not mounted, I tried then to mount sda2: it doesn't recognize crypto_luks.
Then I tried "cryptsetup status /dev/sda2", but of course it says it doesn't find the device (since it's not mounted)
PS - I have an instable access to internet
