Description of problem:
glusterfs 3.6 is supporting replica 3 volumes, specifically for RHEV HC use case. The RHEVM environment however, does not allow a replica 3 volume to be created. An existing replica3 volume can be extended by not created in rhevm 3.5
Version-Release number of selected component (if applicable):
3.5
How reproducible:
Steps to Reproduce:
1. attempt to create a replicated volume with a replica count other than 2!
2.
3.
Actual results:
The replica count is not an editable field in the UI
Expected results:
The UI should allow a replica count to be specified within the supported range
Additional info:
The issue here is workflow related. The replica count is a facet of a volume, and yet the value for a replica count is editable only when adding bricks. Once a volumes replica count is set, adding bricks should not have an editable field for replica count at all - every additional set of bricks has to adhere to the replica count for the volume.
My suggestion is just to change where the editable fields are. Make the Add volume replica count editable - I'd recommend a select box not free text to keep the replica count to a supported level. Then within add bricks the replica count becomes visible only as a cue to the admin for the number of bricks that need to be added.
