When I boot with the F29 MATE-Compiz live spin, it can't see the RAID1 array. There's nothing but the 'control' entry in /dev/mapper directory. There's no SSD (/dev/sda or /dev/sdb) visible to fdisk. And the only devices available in /dev/disks/by-* are those of the live image. I'm looking for any doorknob in the dark. --Doc Robert G.
