Version-Release number of selected component (if applicable):
4.4.4


How reproducible:


Steps to Reproduce:
1. Login to administration portal
2. Navigate to Storage -> Domain -> New 
3. Select gluster type & disperse volume and submit

Actual results:
Storage Domain created.

Expected results:
It should fail as disperse volume is not supported

Comment 3 SATHEESARAN 2021-05-04 00:27:28 UTC

This bug is to prevent users from using disperse volume for ovirt/RHV storage domains,
which is not supported though. This information is clearly documented in the RHHI-V installation guide
that replicated, arbiter, distributed-replicated, distributed-arbiter and single brick volume are the only
supported volumes for RHHI-V deployments.

This was discussed in the last RHHI-V sprint planning meeting and decided to target this bug for 
the next z-stream release of ovirt

Comment 6 SATHEESARAN 2021-06-21 07:29:34 UTC

The dependent oVirt bug is already verified.

Comment 7 SATHEESARAN 2021-06-21 07:29:50 UTC

Tested with 4.4.7.4-0.9.el8ev

On the hyperconverged virt + gluster cluster, created a new gluster volume of type disperse from command line interface.
Tried to create a new storage domain with this gluster disperse volume and that failed with the warning:
"Error while executing action: Unsupported Gluster volume type, volume: disperse, volume type: DISPERSE. Please use the replicate type. To recover existing, migrate it to the supported type."

Corresponding error message is also found with the engine.log
