Hi All, I followed the thread "Food for thought: add something like cutter to IPaddr2 (or portblock?) RA" (http://lists.linux-ha.org/pipermail/linux-ha-dev/2008-October/016196.html) with great interest.
I am working on a cluster of Master OpenLDAP servers using PaceMaker and OpenAIS. The problem I have lies in the replication between the master server that holds the IP address resource and a replica server. In the "refreshAndPersist" replication mode that is being used, the replica polls the master server for updates, then the connection between the replica and the master server is maintained, and the replica is waiting for subsequent updates from the master server. In the event of a failure of the initial master the new master is taking over the IP address resource, but doesn't know anything about the previous persist stage, therefore is not able to send new updates to the replica. An RST needs to be sent to the replica in order to terminate the existing session and force a polling retry from the replica, or the replica would wait for the session to time out. I was wondering whether some work has been done as far as the implentation of the tickle ACK feature in IPaddr2 RA is concerned. Thanks. -- Sam _______________________________________________________ Linux-HA-Dev: Linux-HA-Dev@lists.linux-ha.org http://lists.linux-ha.org/mailman/listinfo/linux-ha-dev Home Page: http://linux-ha.org/
