When using native glusterfs its not clear to me how to configure the
types of storage.
As described in the glusterfs docs [1] there are multiple types of
volume that can be created (Distributed, Replicated, Distributed
Replicated, Striped, Distributed Striped).
In the example ansible inventory file [2] you are suggested to set up
the glusterfs_devices variable like this:
[glusterfs]
node0 glusterfs_devices='[ "/dev/vdb", "/dev/vdc", "/dev/vdd" ]'
node1 glusterfs_devices='[ "/dev/vdb", "/dev/vdc", "/dev/vdd" ]'
node2 glusterfs_devices='[ "/dev/vdb", "/dev/vdc", "/dev/vdd" ]'
But how is the way those block devices are utilised to create a
particular type of volume?
How would you specify that you wanted multiple types of volume
(presumably each with its own storage class)?
Thanks
