Please forgive my noobishness with ZFS, raid and FreeNAS... I am trying to get max storage space out of 3x 2TB drives + 2x 1TB drives with single disk parity like Raid5. It's for backups and long term storage so write/read performance is not very important here. Space is #1, but I do need it to handle a SINGLE drive failure. Is it possible to configure them in a ZFS RAIDZ with the two 1TB drives striped in Raid0, providing a fourth 2TB drive. With that, could I then stack a Raid5 on top of the 4x 2TB drives? If possible, is that the best way? Would I have to configure it using the command line? The best solution I can get working in the GUI gives me just 4.4TB total with all disks in RAIDZ... I was hoping to get 6TB + 2TB for parity. I was getting 4TB before adding the 2 extra 1TB drives. Surely there is a way to use the 1TB drives without making a separate pool?
I just need a little expert advise on this one. TIA!
