--------------------------------
Summary: Releases file handles when deleting storage groups
Key: IOTDB-1649
URL: https://issues.apache.org/jira/browse/IOTDB-1649
Project: Apache IoTDB
Issue Type: Bug
Reporter: Xinyu Tan
Attachments: image-2021-09-08-16-59-01-998.png
Currently, all data is deleted after the "delete storage group root.*" command
is successfully executed on the client. That is, no data exists when the "show
storage group" or "select * from root" command is executed. However, disk space
usage does not decrease.
If lsof -p:pid is used,we can see that the handle of files are not released,
causing the operating system to fail to delete the file.

After the IoTDB process is killed, the disk space usage returns to 0.
