Reconfiguring disk

Hi,
I just finished installing RH4 in a DL380G4 machine with 146G disk.
However, everything was in the / directory when I do df -k. I want somehow to partition it such that it would be mounted to diff lvol like below

Filesystem 1K-blocks Used Available Use% Mounted on
/dev/cciss/c0d0p2 6048352 229676 5511436 5% /
/dev/mapper/vg0-lvol7

/dev/mapper/vg0-lvol4
8063408 172072 7481736 3% /var

Do I need to reinstall or can you help me with procedures to reconfigure it. thanks much.

You probably don't have enough "spare" space to create new logical volumes to move the data. So, probably, your best option is reinstall if you "just finished" the installation.

Thanks for the prompt reply. I was thinkin samething. I have problems reinstalling it. Is it the same as putting the first RH disk1 then reconfigure it? I remember I forgot to manually partition it thats why it automatically did the default one. during partitioning will it automatically map lets say /usr to lvol1 then var to lvol 4 and so on.........

You must manually reconfigure the logical volumes if you want another filesystem layout than the default "all in /".

See:

http://www.redhat.com/docs/manuals/linux/RHL-9-Manual/custom-guide/ch-lvm.html

It's an old version, if you check the RHEL installation guide you find the same information.
