Description Lon Hohberger 2005-03-15 20:48:21 UTC 
Description of problem:

rgmanager will hang during shutdown if two nodes get into a
relocate-to-eachother deadlock.


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


How reproducible: 50% on 3-node cluster


Steps to Reproduce:
1. run rgmanager on 3 nodes
2. run "while [ 0 ]; do clusvcadm -r foo; done
3. kill rgmanager with SIGTERM on all nodes at near-the-same-time
  
Actual results:

Two nodes end up with threads trying to relocate the service to one-another.


Expected results:

Clean shutdown.  It does not matter what the return value from the relocate
request is.

Additional info:

This is probably a simple logic error somewhere in the code.

One way to solve this (and all future problems like it) is to only allow stop &
disable requests during shutdown.
Comment 2 Lon Hohberger 2005-03-16 23:23:37 UTC 
I have (mostly) a fix for this.  Still testing though.
Comment 3 Lon Hohberger 2005-03-21 21:08:30 UTC 
Fixed in CVS
Comment 4 Lon Hohberger 2005-05-06 20:46:07 UTC 
These have been fixed in CVS for some time; closing
