Hi! What would be the recommenden setup for the following: 2 servers which are the storage device (mirrored with drbd,exported via iscsi) the shared storage is imported via iscsi on 3 servers with ocfs2 on top: normal operation: one server web and ftp one server mail and dns1 one server mysql and dns2 every server can run every service in case of a failure so: 1: all configurations must be stored on the shared storage 2: services and ip's are controlled and moved via pacemaker/corosync my question: when adding a slave to the master ispconfig then: i must use the virtualip adress which is moved through the servers and should all services be checked on the slave when added? best regards karl
