Description Lon Hohberger 2004-09-02 09:38:22 EDT
Description of problem:

If the cluster quorum dissolves, all remaining nodes halt services (as
expected).  If one or more services fails to stop cleanly, resources
could still be allocated on the owners of those services.

When a new quorum forms, it's conceivable that the initialization
(e.g. stop-before-start) would also fail, since the previous stop
attempt failed.

If a service has an ordered failover domain configured and, when the
new quorum forms, a higher-priority node than the previous owner is a
part of the new quorum, the service will be started on the new, higher
priority node.

At this point, there is a potential for resources to be allocated on
multiple members.

Version-Release number of selected component (if applicable):
1.2.3, 1.2.9, 1.2.12, 1.2.16

How reproducible:
Theoretical problem.

Reboot the node immediately if it can not free clustered resources
after a loss of quorum.
