nvharikrishna opened a new pull request, #4950:
URL: https://github.com/apache/cassandra/pull/4950
Adds the minimum_cms_size_fail_threshold guardrail that fails an
operator-requested CMS reconfiguration (nodetool cms reconfigure / JMX) when
the resulting CMS size (aggregate replication factor across DCs) would fall
below the threshold.
- Config-driven, default -1 (disabled); valid values are -1 or >= 3
- Enforced only on operator-initiated reconfiguration, not the automatic
reconfiguration on topology changes
- Skipped for clusters smaller than the threshold
- Fail-only (no warning threshold)
