Description of problem: ----------------------- Currently the RHGS volumes created for RHHI-V are of replica 3 or arbitrated replica 3 volume only. RHHI-V also supports single brick volume. For this use case, gluster-ansible role should support creation of single brick volume ( distribute volume with single brick ) Version-Release number of selected component (if applicable): -------------------------------------------------------------- RHHI-V 1.5.z gluster-ansible-roles-1.0.4 How reproducible: ----------------- Not applicable Steps to Reproduce: ------------------- 1. Try to create single brick distribute RHGS volume by having single host entry Actual results: --------------- No way to create single brick distribute volume Expected results: ----------------- gluster-ansible role should support single brick distribute volume
Make sure that the granular-entry-heal option is not turned on for the distribute volume. As this option is not relevant for the distribute volume. Does this item needs a separate bug to be tracked ?

Can this be targeted to 3.4 U3 or U4?

Commit: https://github.com/gluster/gluster-ansible-features/commit/99b688dcdd50 fixes the issue.
Additional information here is that the new virt profile for distributed volume is now available with the name 'distributed-virt' The following way used to optimize the distribute volume for virt store usecase: # gluster volume set <vol> group distributed-virt

If so, this can be set from the role by setting the: gluster_features_hci_volume_options variable.
(In reply to Sachin P Mali from comment #12) > In release stakeholders meeting it was agreed to push this bug out of > proposed list of 3.4 BU4, and to be considered for a future batch update. This bug is needed for RHHI 1.6 as we move the deployment flow to be based on gluster-ansibles. Can this decision be re-evaluated as the verification of bug will be done by RHHI QE?
Tested with gluster-ansible-features-1.0.4-3 distributed volume is created as part of single node deployment and required volume options are set on it
