Right. I am considering ordering one of these new 8TB hard disks so I
can raw copy the raid partitions before I try anything drastic.
Unfortunately even 8TB won't fit 4x3TB of data. :-/ I am fairly
certain my data is still good since all disks have a clean bill of
health and other partitions on them worked with bonnie. So, I figure
my biggest risk right now, is doing something else stupid.

The system remains bootable as the uefi+boot+root filesystems were on
RAID1 x4 arrays and not the data RAID5 array. I'm hesitant to take
action until I find away to store the raw partitions, but installing
3.19 and booting that from my existing root partition sounds harmless
enough.

The system does not have a CD-ROM and has insufficient SATA connectors
to attach one. I could try booting via a USB drive, though.
