Clustersetup with pacemaker/corosync

[coolcat1975]

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
