[jira] [Created] (HDDS-9428) [snapshot] Exclusive size not populated properly when an intermediate snapshot is deleted in a chain
Jyotirmoy Sinha created HDDS-9428:
-------------------------------------
Summary: [snapshot] Exclusive size not populated properly when an intermediate snapshot is deleted in a chain
Key: HDDS-9428
URL: https://issues.apache.org/jira/browse/HDDS-9428
Project: Apache Ozone
Issue Type: Bug
Components: Snapshot
Reporter: Jyotirmoy Sinha
Steps :
# Create vol/buck and key
# Create snapshot snap1
# Create snapshot snap2
# Delete key
# Delete snapshot snap2
# Create snapshot snap3 before the snap2 is reclaimed
# Check exclusiveSize of all snapshots
Expected behaviour - exclusiveSize of snap1 should be the size of the key, since the key is now only held by that snapshot.
Observed behaviour - exclusiveSize of snap1 is 0
Snapshot contents -
{code:java}
# ozone fs -ls -R ofs://ozone1/vol1/buck1/.snapshot
drwxrwxrwx - om om 668 2023-10-11 06:43 ofs://ozone1/vol1/buck1/.snapshot/snap1
-rw-rw-rw- 3 om om 668 2023-10-11 06:43 ofs://ozone1/vol1/buck1/.snapshot/snap1/key1
drwxrwxrwx - om om 0 2023-10-11 07:10 ofs://ozone1/vol1/buck1/.snapshot/snap3 {code}
Snapshot details -
