Hello,

ok i have configured it in pacemaker / crm

Since the config has stonith/fencing it has many problems,
after reboot the nodes are unclean and so on, i need an
automatic Hot Standby...

When i power off the master box - the slave resources dont came up,
the slave always says then the master is "online" - but the machine
is powered off...

Logs that may be interesting:
master corosync[1350]: [QUORUM] This node is within the non-primary
component and will NOT provide any services.
master warning: do_state_transition: Only 1 of 2 cluster nodes are
eligible to run resources - continue 0
notice: pcmk_quorum_notification: Membership 900: quorum lost (1)
notice: crm_update_peer_state: pcmk_quorum_notification: Node
slave[1084777474] - state is now lost (was member)
notice: stonith_device_register: Added 'st-null:0' to the device list (2
active devices)

The config is now (why there are that many "^O" ? I never wrote
them, but the crm shell works.)
