[Pacemaker] failed actions after resource creation

[andreas graeper]

thanks awfully for all your answers.
i started reading about ha/cluster/drbd/pacemaker/.. two weeks ago. it is
not yet easy to precise my questions.

different os on test-environment only, but i already decided to have equal
os for testing, too.
crm configure <<EOF .. # great !!!

my situation: two Nodes n1,n2 and all services (that must not run twice,
and are managed by pacemaker) run on one node only. the other
shall take over in case the first fails. cause both machines are running,
you may say, that some services run on n1, others on n2. but this moment
i have only some services that depend on drbd:Master + IPaddr + Filesystem,
so they have to run on one node. the rest (for today) is simply running on
both nodes
or not (pacemaker is not aware of).

but a new question (to come closer to understand in full depth ..ö..)
when using location-constraints (more than two nodes and on one node a
service (its binary) does not exists, negative location-constraint )
would the resource-manager not complain about missing service (' .. not
installed') ?

thanks
andreas
