You should have made it a primary partition. An extended partition is 
usually used as a container for situations where you want more than 4 
partitions.

I think this is built into anaconda. You could setup a partition with it 
and not actually go through the installer.

You might be able to go back into fdisk and remove all partitions and 
then recreate a primary partition, toggle the partition type and then 
start over carefully.
I would expect the GUI for lvm management could handle this task. I have 
not used lvm for a very long time bu did use the GUI lvm manager 
successfully. Hopefully s-c-lvm is getting better.
