[juno2]

Is there any tools that can defrag the system ? thx.

Hi,
you can use fsadm.
If you installed onlinejsf, here i attach the man page, because easily you are missing it :)

Look at the various options...

If you have Advanced JFS installed, you can use fsadm for this.

Check man page of fsadm_vxfs for details.

You cannot defrag hfs. It does some defragmentation by itself. JFS can be defraged by fsadm

[Brian DelPizzo]

bring up the man page for fsadm_vxfs... You can defrag the directories and the files. I run this once a week on systems with lots of filesystem activity.

To defragment directories and extents having OnlineJFS rune the following commands:
fsadm -F vxfs -d -D /dirname
fsadm -F vxfs -e -E /dirname

Hello!

If you have online JFS than you can use fsadm
with flag for defrag.
