Hello every one.
Is there any thing on FC3 for General maintenance , like scanning disk Defragment ...
It's fsck
DO NOT RUN THIS PROGRAM ON A MOUNTED FILESYSTEM
The system will normally run fsck itself at reboot time if it feels it is necessary (after a certain number of times the filesystem is mounted, or after the machine was shut down without cleanly unmounting the filesystem), so you don't need to run it yourself unless you're having specific problems (usually problems preventing the system from booting).
