I am having the same issue from CLI and trying to use existing gluster storage
(server1:/gluster_bricks/engine).
Error:
[ INFO ] TASK [Add glusterfs storage domain]
[ ERROR ] Error: Fault reason is "Operation Failed". Fault detail is
"[Failed to fetch Gluster Volume List]". HTTP response code is 400.
[ ERROR ] fatal: [localhost]: FAILED! => {"changed": false,
"deprecations": [{"msg": "The 'ovirt_storage_domains'
module is being renamed 'ovirt_storage_domain'", "version": 2.8}],
"msg": "Fault reason is \"Operation Failed\". Fault detail is
\"[Failed to fetch Gluster Volume List]\". HTTP response code is 400."}
Please specify the storage you would like to use (glusterfs, iscsi, fc,
nfs)[nfs]:
If you found a solution can you please share.
thanks,
