This is business as usual. The discovery order isn't guaranteed. Without async scan it depends on machine deterministic things like the order the bios lays out the PCI bus, but that's not going to be constant across machines. Async scanning just makes reordering less machine hardware dependent. The way to cope with this is to mount devices by device id or uuid.
