Ok I'm very new to linux based platforms, specifically openfiler, I'm trying to set this up on a laptop, when I install and go with the default partitions I obviosuly have no space left for creating volumes, what way do I need to partition this to have space for volumes?
what is sda1 sda2 sda3 etc? and what does the / mean ?
I'm looking for the basics :  )

What type of service you want this openfiler setup to provide. SMB and NFS shares do not require a separate volume partition.
You can use directories within the existing file system to share.

/dev/sda1 /boot 102MB
/dev/sda2 / 15000MB
/dev/sda3 swap 2000
you will have some 60GB available.

You may want to explore using LVM.

Ok that worked I can see the 60 gig and add volumes etc I also used this really good link http://www.youtube.com/watch?v=M-ps75Ob2p4 
I wanted to remove everything to start from scratch but I cannot seem to delete the volumes from the volume group, they are not in use and all iscsi targets and lun mappings have been removed, I can edit them and select to create snapshot but the delete button does nothing?

Ran into a similar problem, you have to login into (SSH using putty) the system and then delete the volume using fdisk /dev/sda
use the p (print) to see how/what the setup is. and make sure not to delete the first three partitions.

Since you are building this on a laptop, is this for testing/exploration/evaluation purposes?

See if you have these volumes created under the LVM and you would need to use the lvremove to delete the partition/valume
LVM commands:
pv-Physical Volume
pvscan
pvdisplay
lv-Logical volume
lvscan
lvdisplay

you can have multiple Logical volumes in a physical volume

LVM is the logical volume manager.
It has more flexibility than the raw partitioning you used for your OS setup.
It provides the flexibility of adding addional space from other drives and making it appear as a single resource. Using LVM the resources become available immediately versus raw device which often requires a reboot.

LVM is what openfiler interface uses when it creates volumes.

You should take sometime to see it.

If you are setting up openfiler for real, check out the use of RAID and LVM for the OS and the data.

LVM is a logical volume manager for the Linux kernel; it manages disk drives and similar mass-storage devices, in particular large ones. The term "volume" refers to a disk drive or partition thereof.
