[linux-lvm] /dev/dm-0 instead of /dev/mapper/mygroup-myvol in "mount" output

[Benjamin Henrion]

Hi,

I have managed to setup an LVM loopback file as a harddisk to mount.

Now, I need the vzdump utility to detect the fact that it is LVM
based, and it keeps saying that it cannot detect the LVM volume group:

"unable to detect lvm volume group"

Everything works fine when mount displays that the file is mounted
with /dev/mapper/mygroup-myvol, on the opposite, it does not work when
mount outputs /dev/dm-0 in its list.

Any idea how I could force mount to use /dev/mapper/mygroup-myvol
instead of /dev/dm-0?

Best,
