Ist it possible to avoid this /dev/mapper-generation, if I partitioning
lvm-devices? My problem ist, that Im not able to export the whole device
i.e. as iscsi, if some sub-device is mapped in /dev/mapper/... (says,
its busy then ..).

At the moment I always have to delete these subdevices via kpartx -d
/dev/myvg/.. (or dmsetup remove ..) before exporting it, which is a bit
annoying.

I took a look into 10-dm.rules, but have no idea, what to do.

Regards,
Oliver
