defrag...

[newbie]

Is there a command that'll defrag the disks on Linux?
I currently use mandrake 9 & redhat 8

Thanks

You don't need to defrag Linux and Unix filesystems as long as you have a little free space in your harddisk.

In general, *nix filesystems do not get fragmented (which is another reason *nix is so great =) If you're using ext2/3 or a Journaling-type filesystem, then you don't need to defrag because it was built in a way so that it handles fragmentation more efficiently (unlike the windows filesystems).

Disregard my previous post.

you can also use the command


FSCK -y

 

[linux_0]

you can also use the command


FSCK -y

You should NEVER EVER run

[code:1:a26ee2d2d1]

fsck -y

# or

fsck

[/code:1:a26ee2d2d1]

on a mounted filesystem!!!

You should always run fsck on an unmounted filesystem.

If you run fsck on a mounted filesystem severe filesystem damage may result.

Please pardon the allcaps above but it's very important advice.
