Hi, I do not agree, that's not because we have to start manually HA soft on a rebooted node that we can say "manual HA" ... I've already had lots of configurations with HA solution, from HACMP (IBM) , Cluster Suite (RH) and finally Pacemaker, and none of users wants an HA auto start at boot time for an obvious reason : if it is a breakdown that brokes the node after each boot (i.e a little HW problem, etc.) it will always be fenced a short while after reboot and at worse may disturb other node(s) which are always working . So in this case, you can't say "better to fix the problem which leads to repeated reboots" as before the breakdone there was no problem ... that's why I personnally (and it is always recommended) never recommend to start HA at boot time. So I'm not fan of "HA autostart " ;-)

Unless there is a problem that repeatedly causes the node to boot, it should be OK to automatically join the cluster. Otherwise one might get quorum problems. IMHO it's better to fix the problems that cause repeated reboots, rather than make cluster startup manual. Isn't "automatic" a prerequisite for HA? ;-) I'm not a fan of "manual HA".
