Hi Team I am observing some obsolete files in Cassandra 2.0.14 which are already compacted but not removed from the system after compaction. As per CASSANDRA-7872 <https://issues.apache.org/jira/browse/CASSANDRA-7872> , after GC grace period has passed the sstables are open for read again and can lead to data resurrection. I am facing disk crunch (90% full ) as well and need to remove those obsolete files ASAP.
To avoid this what should be our strategy? I am thinking on following lines 1. Stop the Cassandra server. 2. Remove the obsolete files manually. 3. Start the Cassandra server. Regards Manish
