Talk:Create root filesystem snapshots with LVM
Grub2 doesn't boot with the root volume snapshot on - it gets to this:
Waiting 10 seconds for device /dev/mapper/ ... ERROR: Unable to find root device You are being dropped to a recovery shell
If you type exit at the prompt the boot sequence occasionally resumes, or you can mount the /dev/mapper/... under / and type exit. But this is not a real solution, something needs to be fixed in mkinitcpio. Hint: "mount: /dev/mapper/myvg-mylv is already mounted or /new_root busy"
Also 'grub-mkconfig -o /boot/grub/grub.cfg' hangs when the root lvm snapshot is on :-(
