             Summary: Snapshot true size is miscalculated
                 Key: CASSANDRA-17267
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-17267
             Project: Cassandra
          Issue Type: Bug
            Reporter: Paulo Motta
            Assignee: Paulo Motta


As far as I understand, the snapshot "size on disk" is the total size of the snapshot, while the "true size" is the (size_on_disk - size_of_live_sstables).

I created a snapshot on a cluster without traffic and I expected the "true size" to be 0KB since the original sstables were still present, but this didn't seem to be the case:

{noformat}
$ nodetool listsnapshots
Snapshot Details:
Snapshot name Keyspace name Column family name True size Size on disk
test          ks1           tbl1               4.86 KiB  5.69 KiB

Total TrueDiskSpaceUsed: 4.86 KiB
{noformat}
