Description Adam Litke 2015-10-20 13:08:43 EDT
Description of problem:

When initiating a live merge, ovirt-engine sends a duplicated, invalid merge call which results in a vdsBroker InvalidCall error.  This error causes the whole compound command to fail regardless of the actual outcome of the merge on the vdsm host.


Version-Release number of selected component (if applicable):
ovirt-engine-3.5.4.2-1.fc20.noarch
vdsm-4.16.27-7.gitd10cd66.el7.x86_64

How reproducible:
Always


Steps to Reproduce:
1. Create a snapshot
2. With the VM running, attempt to remove the snapshot

Actual results:
Engine reports merge has failed but it has succeeded on the host.

Expected results:
Engine tracks the merge to completion and properly handles the outcome (including cleaning the merged volume).

This was introduced by a local change and got mischaracterized as a released bug.  Sorry for the noise.
