    Is this anything to do with virtualisation, or is it a hardware issue?

        Do you mean a Dell PowerEdge 2950 which is a server?

            You would need to destroy the LUN to reallocate the space.

            Can you please tell us what your storage actually is as a PE2950 is a server and has no iSCSI capabilities.

              Hi ,

              we have implement a freenas on this server , so you mean to say we need to remove the lun0 first then only we can create ? Also is it possible for a freenas to support 2 or more lun on storage.

              Thanks...

                I have no experience with freenas but with our EMC storage we would need to remove the LUNS from the raid group to re-jig them to the sizes we required.

                No idea on the others.

                Probably the best place to start would be here

                  Yeah, but with NetApp you can resize it on the fly.
                  But with Freenas I think you'll need to destroy them and recreate them again.
