Maybe you can try
lvcreate -L 2.5g -s -n rsnap /dev/rootvg/rootlv

Already faced this kind of situation on previous RH releases (4.3 ?) where /dev/mapper could not (yet) be used wit= h=20 some LVM commands.

Hi Folks,

Read through the doc and tried to = create a snapshot lv for rootlv by doing, but failed.
