I am facing one issue with our Cassandra cluster. Details: Cassandra 3.0.14, 12 nodes, 7.4TB(JBOD) disk size in each node, ~3.5TB used physical data in each node, ~42TB whole cluster and default compaction setup. This size maintain the same because after the retention period some tables are dropped.
Issue: Nodetool status is not showing the correct used size in the output. It keeps increasing the used size without limit until automatically node shutdown or until our sequential scheduled restart(workaround 3 times week). After the restart, nodetool shows the correct used space but for few days. Did anybody have similar problem? Is it a bug?
