Description Ramesh N 2014-10-15 06:58:15 UTC

+++ This bug was initially created as a clone of Bug #1144456 +++

Description of problem:

When newer versions of RHS nodes are released, there's an error in adding these nodes to already released version of RHSC

For instance, we are unable to manage RHS 3.0 nodes using existing RHSC 2.1 U2 installations

The error is 
"Host xxx is installed with VDSM version (4.14) and cannot join cluster yyy which is compatible with VDSM versions [4.13, 4.9, 4.11, 4.12, 4.10].
"
Version-Release number of selected component (if applicable):
2.1

Cause:
RHSC VDC version was changed to 2.1 to reflect that RHS release name..and this has caused this feature to break.
VDSM reports supportedENGINEs = ['3.0', '3.1', '3.2', '3.3', '3.4'] which does not match the VDC version = 2.1

Comment 2 Ramesh N 2015-09-03 07:11:30 UTC

Its working in RHSC-3.1. We can add RHS 3.0 nodes to RHSC 3.1 with 3.4 cluster compatibility.
