Hi list,
i configured pacemaker to take care of a three node drbd stetup but the monitor
on the stacked drbd resouce failed and the resource never gets started.
Doing the necessary steps by hand everything works fine (on-node-with-ip:
drbdadm --stacked adjust mysqlstack ; drbdadm --stacked primary mysqlstack)
is it possible that the drbd-monitor can't deal properly the a stacked-resource
or do i miss something in my configuration?
