Linux Delete file does not free up space

Source: Internet
Author: User

In Linux or Unix systems, deleting files via RM or File Manager will unlink the file system from the directory structure (unlink). However, if the file is open (a process is in use), the process will still be able to read the file and disk space is always occupied. And I deleted the Oracle alarm log file deleted when the file should be in use

Workaround

First get a list of files that have been deleted but are still occupied by the application, as follows:

[Email protected] ~]# lsof |grep deleted

Oracle 12639 Oracle 5w REG 253,0 648 215907/home/oracle/admin/dbticb/udump/dbticb_ora _12637.TRC (Deleted)

Oracle 12639 Oracle 6w REG 253,0 16749822091 215748/HOME/ORACLE/ADMIN/DBTICB/BDUMP/ALERT_DBT Icb.log (Deleted)

。。。

Close the appropriate app.
