Assuming that people are equally new to both, if you limit yourself to only what v1 could do, then pacemaker is just as easy to configure. But of course no-one does that, because v1 couldn't do very much at all - not even checking if all the resources in a group are started. Thats the difference, whereas you hit a dead end with v1, pacemaker lets you keep going and create a useful cluster. Or are you really trying to claim that: linuxha1 IPaddr::192.168.85.3 httpd smb is fundamentally less complex than primitive IP ocf:heartbeat:IPaddr params ip="192.168.85.3" primitive http lsb:httpd primitive samba lsb:smb group v1-group IP http samba location prefer-ha1 v1-group inf: linuxha1 More verbose, yes. But more complex?
