Dear Maintainer,
lvcreate fails with --type vdo option.
root@debian:~# lvcreate --type vdo -n vdo0 -L 15G -V 15G VG/vdopool-debian
modprobe: FATAL: Module kvdo not found in directory /lib/modules/6.10.6-amd64
/sbin/modprobe failed: 1
vdo: Required device-mapper target(s) not detected in your kernel.
Run `lvcreate --help' for more information.
Loading the dm-vdo module solved the bug.
root@debian:~# modprobe dm-vdo
