At least it can keep things operating while we get parts out. Shipped a number today, placed another order for the new vendors drives. I can confirm that heat is an issue with SSDs.
As root, on the unit, decide where you are going to place an image, then dd if=/dev/zero of=/path/to/loopback/raid.img bs=1 count=1 \ seek=32G losetup /dev/loop0 /path/to/loopback/raid.img mdadm --grow /dev/md0 -n3 mdadm /dev/md0 --add /dev/loop0
This will copy the OS to the a file, and we can (later if need be) recover from problems. Say, 2 OS drives dying (which is the failure mode that caught our eye).
But more than that, it will let you keep operating, albeit slowly, in the event of a complete SSD failure, and continue to operate while we get new parts out.
