You’d have to run your Gluster cluster separate from OpenShift if you want
a different volume type I’m guessing.

glusterfs setup

2018-03-28 Thread Tim Dudgeon 
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
Tim
