If you delete an open file, it doesn't really get deleted until it gets closed. du won't count it but df will. To show you the open files, use lsof: # lsof / In order to fix it, you will need to shut down the application that has the deleted open file or figure out how to tell the app to close it. -- Ed Wilts, RHCE Mounds View, MN, USA mailto:ewilts@xxxxxxxxxx Member #1, Red Hat Community Ambassador Program -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
