I did a POC on CCM, removed sstable_activity sstables files from directory
after stopping the node. Restarted the node, sstable_activity table was
generated again. You can verify it in your test environment and see if node
is working fine without any issues. Important thing is to validate any step
Allow me to simplify the question:
Are there any tables under the system keyspace, if deleted, will rebuild
themselves safely or could be configured to be rebuilt without trashing the
entire node?

Hi Manu,
The 2/2 indicates that there are two containers and each is in the ready
state. As Vishal suggested, run kubectl describe pod to get more
details. You also use kubectl get pod -o yaml. The former will
include events in the output. You can run nodetool commands like this:
$ kubectl -n c
Agree. We were planning same change and tested multiple scenarios with
conclusion that it needs downtime to be on safer side. With right
automation in place implementation can be made faster but not without
downtime at least in our case.

I plan downtime for changes to security settings like this. I could not come up
with a way to not have degraded access or inconsistent data or something else
bad. The foundational issue is that unencrypted nodes cannot communicate with
encrypted ones.
I depend on Cassandra’s high availability f
Thank you for the expedient answer. That is what we suspected and it's
helpful to get that confirmation.

The optional setting in 4.0 is designed to fix this. Without optional, you
basically have to take an outage - the only control you have is the nature
of that outage.

I have started reading about how to deploy Cassandra with K8S. But as I
read more I feel there are a lot of challenges in running Cassandra on K8s.
Some of the challenges which I feel are

Hello,
We are trying to come up with a safe way to turn on internode (NOT
client-server) TLS encryption on a cassandra cluster with two datacenters,
anywhere from 3 to 20 nodes in each DC, 3+ racks in each DC. Cassandra
version is 3.11.6, OS is CentOS 7. We have full control over cassandra
