Everything looks as it should.

Pull One Drive from the mirror and you get:
Giving up waiting for root device. Common Problems:
 - Boot args (cat /proc/cmdline)
   - Check rootdelay= (did the system wait long enough?)
   - Check root= (did the system wait for the right device?)
 - Missing modules (cat /proc/modules; ls /dev)

ALERT! /dev/mapper/isw.hgbhachhf_Mirror1 does not exist.

Dropping to shell!

BusyBox v1.10.2  ..
(initramfs) dmraid -ay

ctrl-d

ERROR: isw: unsupported map state 0x2 on /dev/sda for Mirror
ERROR: adding /dev/sda to RAID set "isw_hgbhachhf"
ERROR: removing RAID set "isw_hgbhachhf"
