Indeed when you want to flush the system keyspace you need to specify it. The flush without argument filters out the system keyspace. This behavior is still the same in the trunk. If you dig into the sources, look at "nodeProbe.getNonSystemKeyspaces()" when "cmdArgs" is empty:-  https://github.c

First, make sure that you call nodetool flush after modifying the system table. That's probably why it's not surviving the restart. Second, I believe you will have to do this across all nodes and restart them at the same time. Otherwise, cluster name mismatches will prevent the nodes from commun
