I do know that configuring Pacemaker is a tricky business. There are a number of different monitoring and timeout parameters that have to be set just right in order for things like this to work. If the migration takes longer than the default timeout to complete, it can cause Pacemaker to think the resource has failed. I don''t know if that is what you are experiencing, but the clues are in the HA logs. Unfortunately the Pacemaker logs are quite verbose and hideous to try and decipher; that''s where the folks on the linux-ha list may be able to help. --Greg _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
... ok thanks for this link. I had a few resources in one group and now I am running without a group and it works fast and find.
