Description Lon Hohberger 2006-08-08 14:08:37 UTC 
Description of problem:

Sometimes, it takes awhile before membership transitions are processed
correctly.  This should be near-instantaneous after the event is received.


Version-Release number of selected component (if applicable): CVS/head 7-Aug-2006


How reproducible: 80-90%
Comment 1 Lon Hohberger 2006-08-08 14:12:38 UTC 
This seems primarily seems to occur due to the timeouts in vft.c, and sometimes,
this causes services to be in the 'stopped' state.  It appears to be simply that
VF is trying to communicate with the no-longer-listening node, expecting a response.

There are a few possible fixes:
(a) Give up on a node if it doesn't respond
(b) Retry - after re-checking a node's listening status from CMAN
(c) Correct it so that VF doesn't get the wrong membership list (e.g. it
shouldn't try to communicate with nodes which are not listening).

Fixes in CVS
Comment 3 Nate Straz 2007-12-13 17:19:01 UTC 
Moving all RHCS ver 5 bugs to RHEL 5 so we can remove RHCS v5 which never existed.
