No mirrored volume dropdown

[thesilversurfer2009]

Hi. Im new to freenas and am using 2 test disks to learn freenas. I have a 160GB drive and a 250GB drive. Im trying to create a mirrored volume (using the smaller drive to select first) but there does not seem to be any way to create the mirror (using 9.1.1)

I realise that normally the drives would be the same size but thought it would be possible to do this.

Any help would be appreciated.

Thanks

You will have to do this from Shell as the ZFS Volume Manager won't let you create a non-optimal configuration.
