Hi
I am using DRBD (8.4.5) in dual primary mode (with GFS2) on Red Hat Enterprise Linux Server release 7.0 (Cluster, Pacemaker).
Everything workes fine only if a node crashes (i pull the power plug), the shared directory becomes unusable: for eg. a 'ls -l' blocks until the node has rebooted normally.
During this situation the drbd status for the second node is Unknown/Outdated.
I am using the configuration as supposed on the homepage.
Am i missing something ?
Another question: It is possible to define the time when an active node gets informed about another node crash (currently it takes about 2sec before DRBD changes the status of the crashed node) ?
thx
