Description
This is the output of nodetool listsnapshots:
Snapshot Details: Snapshot name Keyspace name Column family name True size Size on disk Creation time Expiration time test ks indexed_table 1.1 KiB 21.22 KiB 2022-04-26T19:13:20.102Z test ks my_table 960 bytes 10.76 KiB 2022-04-26T19:13:20.102Z dropped-1650997415751-my_table ks my_table 989 bytes 989 bytes 2022-04-26T18:23:35.751Z Total TrueDiskSpaceUsed: 0 KiB
Total TrueDiskSpaceUsed does not match the sum of "true size on disk" of all snapshots.
The reason for this is because Total TrueDiskSpaceUsed computation does not include the size of snapshot schema and manifest files.
We should fix the Total TrueDiskSpaceUsed computation to include the the size of snapshot schema and manifest files, so it will look like this:
Snapshot Details: Snapshot name Keyspace name Column family name True size Size on disk Creation time Expiration time test ks indexed_table 1.1 KiB 21.22 KiB 2022-04-26T19:13:20.102Z test ks my_table 960 bytes 10.76 KiB 2022-04-26T19:13:20.102Z dropped-1650997415751-my_table ks my_table 989 bytes 989 bytes 2022-04-26T18:23:35.751Z Total TrueDiskSpaceUsed: 3 KiB
