I have just imaged my system to a 600 GB hard drive and now would like to expand the partitions.

I would like to be able to expand /var and / to keep disaster recovery info on them for each of the other servers in the cluster. What is the best way to do this?

My partitions look like the following:

sda1 /boot 4 GB ext3
sda2 swap 32 GB
sda3 / 145 GB ext3
sda4 /var 90 GB ext3

I am running OES2SP1 on SLES10SP2 and Novell Cluster Services (storage is on the SAN not on these drives).
