Create a glusterfs volume.
name
Name of the gluster volume
bricks
Bricks to create volume from, in <peer>:<brick path> format. For \
multiple bricks use list format: '["<peer1>:<brick1>", \

stripe
Stripe count, the number of bricks should be a multiple of the stripe \
count for a distributed striped volume
replica
Replica count, the number of bricks should be a multiple of the \
replica count for a distributed replicated volume
device_vg
If true, specifies volume should use block backend instead of regular \
posix backend. Block device backend volume does not support multiple \
bricks
transport
Transport protocol to use, can be 'tcp', 'rdma' or 'tcp,rdma'
start
Start the volume after creation
force
Force volume creation, this works even if creating in root FS
CLI Example:
.. code-block:: bash
salt host1 glusterfs.create newvolume host1:/brick
salt gluster1 glusterfs.create vol2 '["gluster1:/export/vol2/brick", \
"gluster2:/export/vol2/brick"]' replica=2 start=True
