Hi All,
I've setup a DRBD two node cluster with heartbeat. But I am having trouble
with my secondary node. No matter how many times I do a sync it still says
"secondary inconsistent". However if I stop the heartbeat service from the
primary the secondary take over the resource.
But If I pull the network plug from the Primary then seconday cannot take
the resources and complain about "at least 1 uptodate disk required"
1/ Please help me to get secondary disk to consistent state.
2/ Simulate network failure won't start secondary (pulling the cable out).
How ever stoping heartbeat gracefully on primary kicks the secondary into
action.
Please find the attached configs for the files.
Thanks heaps,
CP
