hello,
i plan to setup a fileserver with 2 nodes for ha and 1 san-device for
storege.
Bescause the san-device have noch snapshot option (budget), ihave to
snapshot with lvm2 for backup.
so my testsetup with onde node works fine, exept the snapshot.
if I try to snapshot I get
root@kain ~]# lvcreate -L1G -s -n snap /dev/data/home
