Package: lvm2
Version: 2.03.16-2
Severity: normal
Dear Maintainer,
* What led up to the situation?
My system has a mirrored rootfs LV. When snapshoting and merging this
snapshot, the system refuses to boot.
* What exactly did you do (or not do) that was effective (or ineffective)?
My rootfs is vg1/root (mirrored using raid1)
To simulate a snapshot, I do:
lvcreate -s -n root-snap -L 100MB /dev/vg1/root
Simulation of modification :
dd if=/dev/urandom of=/test bs=1M count=40
Merging snapshot :
lvconvert --merge vg1/root-snap
Since rootfs is mounted, the following message is displayed:
Delaying merge since origin is open.
Merging of snapshot vg1/root-snap will occur on next activation of vg1/root.
reboot
* What was the outcome of this action?
Begin: Loading essential drivers ... done.
Begin: Running /scripts/init-premount ... done.
Begin: Mounting root file system ... Begin: Running /scripts/local-top ... done.
Begin: Running /scripts/local-premount ... done.

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

Notice that que root LV is not activated :

* What outcome did you expect instead?
root LV is activated during boot and while system boots.
