I had also the problem. One solution is to add modprobe dm-snapshot >/dev/null 2>&1
to the beginning of /etc/init.d/lvm. After this the next problem occurs. The device-mapper tries something with the hidden snapshot volumes *-cow and *-real I think: device-mapper: unknown target type device-mapper: error adding target to table device-mapper: unknown target type device-mapper: error adding target to table When ignoring the warnings during boot the lvm snapshot works. -- (LVM) Booting fails if a snapshot LV is present on VG https://launchpad.net/bugs/58627 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
