It means the path to the brick, or some preceding directory up the
tree, is marked as being part of a volume, or was part of a volume
in the past.<br>
<br>
From your two commands, you're trying to use the same path twice. In
volume kvm1 you use the same two bricks as kvm2. Two volumes cannot
use the same bricks. Is there a reason you want two volumes? A more
typical use case would be:<br>
<br>
gluster volume create kvms replica 2
onode1:/data/glusterfs/kvm1/brick1
onode2:/data/glusterfs/kvm1/brick1
onode1:/data/glusterfs/kvm1/brick2
onode2:/data/glusterfs/kvm1/brick2<br>
