Hi,
we tried to create a new lv with lvcreate -L 440G vg00 -n lv_datenarchiv.
The lvcreate failed. It seems that lvm can't handle a second drdb device.
It allocates space on nb0 and nb1, but the lvcreate fails with an error
and it is not possible to make a mkreiserfs.
Is this problem fixed in a newer version of lvm?
Thanks in advance
Sven Landtrachtinger
