#
# Test that even after multiple restarts in a WAN context with two segments, the cluster continues to operate correctly.
#
# We can not easily restart the first node, so instead we restart all the other nodes. MTR does not allow multiple nodes
# to be down at the same time, so restarts are sequential.
#
# We can not test any of the actual WAN optimizations from inside MTR and no 
# status variables are provided. So we only check that simple replication works.
