Mirrored boot device - Only one showing in disk list

[Wong_558]

So I am just setting up my first TrueNAS Core installation, and for boot devices, I went with 2x 120GB M2 SATA SSDs hooked up via 2x USB 3.0 enclosures. When installing TrueNAS I was able to see and select both devices, and did so when installing.

Now however when I go to my disk list, I only see one of these devices. I just wanted to make sure this was expected behavior or if I should still be seeing both.

Apologies if this has been answered before, I searched and the results I came up with were rather unrelated.

I'm the least knowledgable around these parts, but I have 2 mirrored boot drives and see them both.

Only an aside but I would recommend SATA connected boot drives, even if that means sacrificing storage drives and overall space. The first install should really be used to gain familiarity, I wouldn't depend upon it until thorough hardware testing is done and you've gained familiarity with it.

Hope that's helpful.
