RN102, Mix Raid 0 and Raid 1?

Ah, I think you may be able to setup a raid 1 volume of 1 tb then use the 2 tb space for a non-redundant volume. I am not sure how to do this though. StephenB has posted that it is possible, but I can't find a method. viewtopic.php?f=24&t=76159

I don't think it is possible with OS6.

If you had a 4 bay unit then you could set up a raid 1 volume on 2 disks and have another disk as a separate volume. Even if this is possible, this wouldn't really be an efficient use of space though as you could a have a 3 disk raid 5 volume with the same overall capacity and

Yes.

davidfregoli, I am a little confused on why you want iscsi LUN for the linux server backup.

But if you want ~3 TB total volume (800 GB +2.4 TB => 3.2 TB) the simplest way is just to get 2x3TB drives or 2x4TB drives and protect everything with RAID-1. You can still use iscsi LUN if you want to for the linux server.

Or go with jbod (though doesn't give you RAID-1 protection for the backups). Then your 2 x 2 TB drives will give you enough space, though you will need to put some other shares on the volume that hosts the iscsi LUN.

Note you could set up one iscsi LUN on each jbod disk, and run two backups (perhaps alternating between them). That's similar to RAID-1 protection.

The main issue with jbod is that you need to manually balance the storage between the two disks. That's easiest if you set things up with more/smaller shares.
