New RN104 System/Volumes Question

[Mook1]

New 104 install using default FW 6.1.8. X-RAID enabled.

I installed 2 new boxed 3TB drives and went through the setup process. No problems.

Q: The GUI when selecting System > Volumes only shows one hard drive. Shouldn't it show 2?

One more: What does JBOD mean specifically RAID (JBOD)?

Did you insert the disk that is not showing up properly? Perhaps the disk is bad?

Here JBOD means there is no spanning (each disk is its own volume). On the RN104, each data volume is still mounted via mdadm. cat /proc/mdstat shows this:

Personalities : [raid0] [raid1] [raid10] [raid6] [raid5] [raid4]
md126 : active raid1 sdb3[0]
      2925416832 blocks super 1.2 [1/1] [U]

md127 : active raid1 sda3[0]
      2925416832 blocks super 1.2 [1/1] [U]

md1 : active raid1 sda2[0] sdb2[1]
      523712 blocks super 1.2 [2/2] [UU]

md0 : active raid1 sda1[0] sdb1[1]
      4190208 blocks super 1.2 [2/2] [UU]

unused devices: <none>

md126 and md127 are the two data volumes in this system.
