What to do if Cassandra reclaimable space is higher than 25 percent
Applies to
Netapp StorageGRID
Answer
When data is deleted and overwritten, Cassandra temporarily contains obsolete data which the system should automatically clean up when there are enough CPU and memory resources available.
In the case this does not happen, investigate the issue by following the guide: StorageGRID meta-data not decreasing after deleting large amounts of data
Additional Information
If metadata usage is low, automatic compaction will not be triggered and the reclaimable space will not decrease.
