---------------------------------------
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}
