I have Ubuntu 10.04 LTS on a 500GB drive. Works great. The drive is 1 partition for the OS and a small swap partition.
I want to shrink the OS Partition to around 300GB so I can use the other 200GB for iSCSI on my network.
If I boot the system with a Live CD, use GParted to resize the partition, will I lose the data or it's ability to boot from that partition?
