Have you tried writing to sector 0, just to take mkfs.xfs out of the picture? E.g. "dd if=/dev/zero of=/dev/rbd17 bs=512 count=1 oflag=direct"? > > Strange thing is, if I use an already existing pool, and create this 80Tb image within this pool, it formats it correctly. What do you mean by a newly created pool? A metadata pool, a data pool or both? Are you deleting and re-creating pools (whether metadata or data) with the same name? It would help if you paste all commands, starting with how you create pools all the way to a failing write. Have you tried mapping using the admin user ("rbd map --id admin ...")?
