Hi, we are planning to run two-node clusters
(for database and file-services) with cluster nodes in different sites with a
fast, but sometimes unreliable network connection. Data should be replicated with
DRBD between the cluster nodes/sites (no shared storage). I’m specially afraid of split brain
here. In this scenario fencing depends on the (unreliable) network connection
between the two sites – in my opinion fencing is unreliable and not
possible in this scenario. What would be the best way to run such a
cluster? Regards, Robert |
