No available disks in ZFS Volume Manager

[Marco_Paris]

Hello,

I have four disks which appear on the View Disks tab. However, when I try to format my disks into a ZFS pool, I can't see them in the 'Available disks' part. I am fresh new to the FreeNas world so please excuse my ignorance.
I am using FreeNas 9.3.

Thank you for your help.

Ok, that's because I had already created a volume which contained all the space with the Configuration Wizard .. My mistake.
