[linux-lvm] strange logical volume issue

[messmate <messmate free fr>]

Hi list,
there is somewhat strange with a lv of mine: lv_usr-local.
Marked as /dev/mapper/vg1_hda1-lv_usr--local    and
as /dev/vg1_hda/lv_usr-local  !

See the (-) differences.

I've tryed to change this without success.
Manually, with lvremove and lvcreate.....

Is there a special way to do this changes ?
Thanks for your help in advance.
