could it be that when start out with an #dmraid with 4 equal drives in #RAID 5 and then add 4 more similar drives at the same time) later that it'll basically RAID0 each of the drives in the RAID5?
(I didn't tell it anything other than lvextend -l 100%FREE, I think. It has been a while. Just wondered why the total capacity is missing two instead of one drive...)
Guess it's time to learn how to tell which topology #LVM choose internally from the lvs/pvs/vgs/... tools output.

Oh, this combination of parameters and features causes lvcreate to incorrectly calculate the extents it needs and the command fails. (Needed to calculate them manually to fully use the drives. Probably could just have yolo-ed it with 89%FREE instead or something)
lvcreate --type raid6 --size 100%FREE --config allocation/raid_stripe_all_devices=1 --name raid6Data --raidintegrity y --raidintegritymode journal --raidintegrityblocksize 512 --autobackup y lvm_vg_<<UUID>>
