Description Lon Hohberger 2006-11-01 21:14:23 UTC

Description of problem:

qdiskd doesn't operate correctly if no heuristics are defined.  The proposal is
to give qdiskd operational guarantees even if no heuristics are defined.  I am
looking for simple things here - just to guarantee behavior in network partitions.

examples:

(a) current qdisk master always wins

(b) High/low node ID always wins

(c) if a node ever finds another node which "sees" more nodes than it does, then
it relinquishes master status and then becomes the minority (and will be fenced)

Comment 1 Lon Hohberger 2007-01-22 22:53:04 UTC

Fixes in CVS; RHEL4 / RHEL5 / head branches.

Comment 2 Kiersten (Kerri) Anderson 2007-04-23 16:53:27 UTC

Fixing Product Name.  Cluster Suite was merged into Red Hat Enterpise Linux for
5.0.  In addition dlm, fence and ccs were merged into the cman package, so
bugzilla should reflect package name where those utilities are located.
