Description Lon Hohberger 2008-01-25 16:45:36 UTC 
Description of problem:

When qdiskd detects multiple masters, all detecting qdiskd instances are
supposed to abdicate their position and elect a new master.  Unfortunately, a
logic error prevents this from occurring in all cases.  For example, if qdiskd
goes to sleep, is evicted, and still thinks it is master, it will complain:

"A master exists, but it's not me?!"

Steps to Reproduce: Unknown; seen in overnight testing
  
Actual results:  Loop with annoying messages

Expected results: Master abdication + re-election

One way to cause this is to corrupt the quorum disk while qdiskd is running.

This is in my local git branch and has already been pushed to master.
