It’s not enough. Promusicae and Google need to be slapped with massive punitive damages every single time they pull this shit.

Well, I’ve found some of the answer.

/volume1 is a single LV on a single VG - no surprise there. There are two PVs comprising it, each of which is a RAID5 group across an extended partition on the disks.

pv0 is /dev/sd[abcd]5 and pv1 is /dev/sd[abcd]6

Now what I find most interesting right now is that SHR supposedly required btrfs to operate - and yet, /volume01 is an ext4 filesystem.

Part of me would like to convert to btrfs, but I’d need a spare 10TB of storage just to back up to, before starting down that odyssey.

More digging, more questions.
