Hi,

I've just updated my FreeNAS 11 to TrueNAS 12 on my QNAP 451+ and the upgrade appeared to OK. (I upgraded because the USB drive that booted 11 failed, so I bought 2 identical USB's and put the latest 12 on.)

During install, I only installed to 1 USB, and now I've put the 2nd USB in and trying to mirror it with `System -> Boot -> Boot Pool Status -> Attach`. At first it complained that da0 existed, so I went under disks and chose "wipe". Now it consisently fails with `Error: [EFAULT] newfs_msdos -F 16 /dev/da0p1 failed: newfs_msdos: /dev/da0p1: Operation not permitted`.

If I run this newfs command in the console it works fine.

Are there any CLI steps to mirror the boot drive? I'm wanting to make sure that if the primary boot USB fails, that it will boot off of the secondary - and thus I can pull it out and replace it.
