Hi,
Recently, we've been experiencing with this problem, we have a 3 node
cluster. Once we started all nodes, all processes are running, but the logs
show they constantly fail on each other, so that the master keeps changing
from node to node. Because of this changing, we constantly run into write
failures.
Here is a portion of the relevant log:
