Is it possible to extent a running cluster with new cluster nodes?
The easiest way is to configure "autojoin any" in your ha.cf file, which is safe if you use sha1 or md5 keys to authenticate in your authkeys file. This allows every new node which knows the key to join the cluster whithout the need for an explicit "node" directive.
The extention should be done without any stop of any resource placed on nodes, which are running in the cluster before we extend the cluster. If it is possible, can I use the "is_managed" attribute to leave the resources untouched, when I stop the cluster, do some changes (like updates), start the cluster and reset the "is_manged" attribute after all changes are done?
Yes, this method worked for me. Set all resourses to unmanaged and make your changes, reenable it afterwards ... but first of all test your updates on a test system ;-) Regards, Andreas _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
