Description Tushar Katarki 2013-11-21 16:58:52 UTC

Description of problem:

split-brains are inevitable in the field either because of network issues or due to bugs in the software stack. 

There is no way currently for storage administrators to be notified of split-brain situations so that they can take remedial action. 

This is RFE (Request For Enhancement) to provide an alerting mechanism to storage administrators of split-brain situations. Furthermore, a mechanism needs to provided to storage administrator to diagnose the situation, identify root cause and take remedial action. This latter part is perhaps a different RFE, but combining it here until we have an wholesome assessment of this entire request. 
 
Version-Release number of selected component (if applicable):

RHSC 2.1 and RHS 2.1 


Additional info:

Alerts should be generated in case of split-brains in 

- client facing network
- server side network 
- or combinations of the above 

If there is a loss of connectivity between the management network (where RHSC is located) with clients and/or servers an alert to that effect also needs to be in place.

As discussed in the triage meeting, a new bug is now opened to track this feature through Nagios. ( Currently Alerts would not be shown in RHSC. They will be shown only in Nagios UI )
---------Note from triage meeting--------------
1033197 - Out, for now. A different bug will be created for monitoring split-brain using Nagios. (Bug 1081900 opened for the same)
