Description Lon Hohberger 2009-04-01 21:12:00 UTC 
Description of problem:

Pacemaker offers superior resource management and dependency tracking to rgmanager in clustered environments.  Effectively, it supersedes rgmanager's functionality in many ways while simultaneously providing users a staged upgrade path.

Resource agents written for rgmanager will work with pacemaker with minimal changes.

Unfortunately, pacemaker and rgmanager are not wire-compatible with one another, so there is no rolling upgrade path for rgmanager users for the rgmanager/pacemaker applications.

That said, with a conversion utility (#456897), it should be possible for pacemaker to provide the same services as rgmanager.

Additionally, because rgmanager now supports 'frozen' services, it should be possible to do a staged transition from rgmanager to pacemaker without affecting service availability:

 * Freeze all services
 * Kill rgmanager on all nodes
 * Convert cluster configuration, but leave all resources as 'unmanaged' in the pacemaker CIB (= config file)
 * Start pacemaker
 * Flip each resource to 'managed'

Version-Release number of selected component (if applicable): 6.0.0
Comment 1 Lon Hohberger 2009-04-01 21:15:01 UTC 
Because a staged upgrade would be required, it may not be prudent to remove rgmanager from the distribution in RHEL6.
Comment 2 Lon Hohberger 2009-04-01 21:15:53 UTC 
Pacemaker has not been included in Fedora yet, however, I expected it to go in to Fedora early after F11's release date.
