You are going to have to reboot to see the new size because the partition is in use. I highly recommend using LVM on the bare SAN volume next time. -Ross

Basically your system won't see the additional space while you're using the partition. if you stop using it (unmount) then you can operate on it and bring it back online. This is where LVM shines, because you can simply add another lun, add it to your lvm setup, and expand the filesystem on the fly. -- During times of universal deceit, telling the truth becomes a revolutionary act.
