hi guys,
I'm a little bit rusty on linux since there is some time since i wrote something in terminal last time.
there it is... i'm trying to add some space to a fresh installed OEL 5.6 as a VM... but I don't know what I'm doing wrong (first I will try to mount a new hdd partition ten I will edit fstab)

Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.
The number of cylinders for this disk is set to 1044.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
