Description Timothy Asir 2013-10-30 10:03:42 EDT
Description of problem:
when a (vdsm) node has more than one nic or 
     a node peer probed using name or 
     its peer probed using an alternate ip,
the remove host task sent from the engine failed with "peer host not found" error.

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

How reproducible:

Steps to Reproduce:
1. Add nodes with more then 2 nics to the engine (rhsc)
2. Remove one node

Actual results:

Expected results:

Additional info:
This error occurs, whenever an engine sends a name or ip of a host to be removed to a node which doesn't aware of or doesn't have the host name or ip entry in its peer list (status). To avoid this, the engine can send gluster host uuid also along with host name to the vdsm and the vdsm can check the uuid and remove (detach) the appropriate host.

patch send to upstream: http://gerrit.ovirt.org/#/c/20731/
Comment 3 Timothy Asir 2013-12-10 04:30:30 EST
This issue occurs due to wrong configuration.
Comment 4 Timothy Asir 2013-12-10 05:35:41 EST
Currently dns configuration is required for rhs. It will work
properly when we have fully qualified domain name for a host.
So that it can uniquely identify the server. This can also be
temporarily configured using host file in /etc/host.

Taking this bug out of Corbett list.
Comment 6 Kanagaraj 2014-05-22 00:04:12 EDT
Moving to ASSIGNED as the patch is abandoned in upstream.
Comment 8 Dusmant 2015-12-28 01:37:39 EST
RHSC 2.1 is EOLed and we don't have any plan to fix this issue.
If you think, this is an important bug to be addressed, pls. re-open it on the latest release. 
I will go ahead and "CLOSE" this bug for this release.
