Bug#320312: Taking LVM snapshots can lead to an unuseable system
Package: kernel-image-2.6.8-2-686
Version: 2.6.8-16
Severity: critical
In sarge I was unable to take any lvm snapshots until I manually
loaded the dm-snapshot kernel module with modprobe.
I took a snapshot of my /usr filesystem, but didn't remove the
snapshot with lvremove before rebooting.
After reboot, not only is the snapshot unavailable, but also the
original filesystem. This makes the system unusable until the
snapshot can be removed.
If I boot kernel-image-2.4.27-2-686, (which fortunately I also had
installed), I don't need to manually load dm-snapshot.
Perhaps this is an lvm bug instead?

Many thanks,
