off course, this can also be done by 'sam' on the fly.

Yes, It is doable.

Hi there,

Just use lvreduce and fsadm to shrink your filesystem.

Hi,

Online shrunk is possible if Online JFS is installed. Just using command

# fsadm -b 70000 /home

For example, suppose your VxFS file system now has a total of 90,000 blocks allocated.
However, you decide you really only need 60,000 with an additional 10,000 blocks for
reserve space. As a result, you wish to resize the file system to a new size of 70,000
blocks. Use fsadm with the -b option to specify the new size of the file system:

Hi,

Yup, HP JFS can be shrunk online. As long as you have Online JFS software on your system.

Check the url below (docID : UFSKBRC00006760) about 'Differences between Base JFS and Online JFS' :

Hope this information can help you.

swlist -l bundle | grep -i online

Will tell you if you have Online JFS installed.

If you have, then use SAM or fsadm as the others have suggested.

Cheers.

You can also use "fsadm -L 2048000 /home" where -L 2048000 is the value in kbytes.
