Hello, What exactly is the right procedure to initialize a cluster. With the following configuration: RAID-b1 with 2 controllers, each having 1 virtualdatabase, each holding 1 backend. I've done the following, as described in the Installation guide: initialize backend on the first controller backup backend on the first controller transfer dump to the second controller enable backend on the first controller restore backend on the second controller eanble backend on the second controller And that's OK But now, when I shutdown the whole with the commands: shutdown virtualdatabase on first controller then shutdown first controller shutdown virtualdatabase on second controller the shutdown second controller All seems OK. The surprise is at restarting the whole. First controller starts normally But seconds disable backend as shown in the following logs: 18:02:55,617 INFO backend.DatabaseBackend.fr-bea Detected backend as: MySQL 18:02:55,686 INFO controller.RequestManager.MATISSEDB Setting new virtual database schema. 18:02:55,738 ERROR controller.recoverylog.RecoverThread Unable to get checkpoint from recovery log. java.sql.SQLException: Unable to get checkpoint disable all backends-192.168.4.201:25322-20070130180224872+0100 from the recovery log (Checkpoint disable all backends-192.168.4.201:25322-20070130180224872+0100 does not exist in recovery log) at org.continuent.sequoia.controller.recoverylog.events.GetCheckpointLogIdEvent.execute(GetCheckpointLogIdEvent.java:96) at org.continuent.sequoia.controller.recoverylog.LoggerThread.run(LoggerThread.java:732) 18:02:55,753 INFO sequoia.controller.connection 10 connections freed on "jdbc:mysql://fr-bea.ago.fr/MATISSE" 18:02:55,829 WARN controller.virtualdatabase.MATISSEDB Virtual database MATISSEDB failed to enable database backend fr-bea from checkpoint (because of : java.sql.SQLException: Unable to get checkpoint from recovery log.) java.sql.SQLException: Unable to get checkpoint from recovery log. at org.continuent.sequoia.controller.recoverylog.RecoverThread.run(RecoverThread.java:168) 18:02:55,829 WARN controller.core.Controller Failed to automatically enable backends, manual resynchronization is probably needed 18:02:55,829 INFO controller.core.Controller Adding VirtualDatabase MATISSEDB So what's wrong in my procedure ? Is my shutdown procedure wrong ? Gérard --
