Or I am wrong? use some kind of STOMOTH (Shoot The Other Machine On The Head). as soon as heartbeat fails, one of the hosts will kill the other. usual weapons are ethernet-managed power strips and manageable ethernet switches (to disable the other machine's port). that way, you're assured that if there won't be two surviving masters. i don't know if drbd (or heartbeat) includes support for that, but GFS (and therefore, CLVM) uses it extensively. -- Javier Attachment:
