Summary: Async tasks should not be allowed in 3.3 compatible cluster in RHEV 3.4

OS: Linux   
Whiteboard:
Fixed In Version: 3.6.0-11 Doc Type: Bug Fix
Doc Text:
Cause: No cluster compatibility check to perform long running tasks like rebalance and remove-brick Consequence: Task is created and volume is locked though node does not have capability to report and update task. This causes volume to be locked for further operations. Fix: Check added to ensure node is capable of supporting gluster asynchronous tasks Result: Works as expected

Description SATHEESARAN 2014-11-17 15:01:13 UTC 
Description of problem:
-----------------------
Async tasks ( rebalancing the volume, removing brick with data migration ) should not be allowed in 3.3 compatible cluster in RHEVM 3.4

Version-Release number of selected component (if applicable):
-------------------------------------------------------------
RHEVM 3.4 ( av13.1 )

How reproducible:
-----------------
Always

Steps to Reproduce:
-------------------
1. Create a 3.3 Compatible Datacenter
2. Create a 3.3 compatible gluster enabled cluster
3. Add RHSS (Red Hat Storage Server) Node to that cluster
4. Create a volume with 2 bricks on the volume
5. Perform Rebalance volume operation
6. Try to perform remove-brick with data migration

Actual results:
---------------
Rebalance and remove-brick with data migration are allowed on the volume

Expected results:
-----------------
Async tasks (i.e) Rebalance and remove-brick should not be allowed

I do consider this to be a blocker for 3.5.0.
Moving to 3.5.1. If you think there is a good reason to block the GA on this, please add the impact.

Sahina,

Could you add - FIXED_IN_VERSION with the correct build, so that it could be verified with ease
Comment 8 SATHEESARAN 2016-02-25 09:44:06 UTC 
Tested with RHEV 3.6.3.3 by RHGS 3.0.4 nodes to the 3.3 cluster compatibility.

Async operations ( rebalance, remove-brick ) on the volume are not permitted in the setup
