> 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.
