Description

rgmanager does not run iterative service placement in the event of failures; it lacks the dependency engine processing required. For example, in the example: * Given a 3 node cluster: "Node A", "Node B", "Node C" * Node "A" and Node "B" are part of failover domain "FD1" * Node "B" and Node "C" are part of failover domain "FD2" * SV1 is in FD1 and running on Node A * SV2 is in FD2 and running on Node B If A fails, SV1 will not recover; rgmanager does not build a list of actions to take at service failures that are related to one-another. There was code upstream at one point to give this sort of multi-action ability to rgmanager, but it was removed long ago: https://git.fedorahosted.org/cgit/cluster.git/commit/?h=STABLE32&id=52685e0f57063583d6af537d1ea2e1539e437372 Instead, the Pacemaker Cluster Resource manager will provide functionality similar to this. Cluster Suite is no longer supported. |
