I installed OES 2 SP3 on SUSE 10 SP4. After installation I tried to extend default size (14.0 GB) of Linux system partition on sda1. SDA has a few hundreds GB of free space. I was trying to use both LVM and EVMS tools, but could not extend sda1. How to extend sda1 size to at least 100 GB during or after installation?

Thank you.
