Modify FileSystems on AIX

Hello - I require some help on How to modify the allocation of space in FileSystems on AIX box:

Presently, In one of the FS I have 30 GB assigned and another FS I have 10 GB. I want to make first FS as of 20 GB and second FS also of 20 GB. Please suggest - How to do that stepwise, I am familiar with Solaris format. But newbie to AIX - Thank you in advance!

# df -g /data/vol1 /data/vol2
Filesystem GB blocks Free Mounted on
/dev/fslv08 30.00 30.00 /data/vol1
/dev/fslv09 10.00 10.00 /data/vol2
#

Regards!!!

You might want to read the manpage of "chfs".

If you expand the FS it is better to first expand the LV under it and only then expanding the FS. You can expand the FS only and rely on the LVM to change the underlying LV for you automatically, but it is better to do it yourself and not rely on the automatic.

Here is a detailed description.

To make a filesystem smaller also use chfs: "chfs -a size=-<nr>...". This will automatically release the PPs fron the LV.

I hope this helps.
