We updated our scenarios that do thousands of lv/pv creates to also add in unique lv tags to each, similar to comment #0, thus causing thousands of additional VG mda writes and saw no command failures. We did however see plenty of "bcache no new blocks for fd" warnings which I believe will be removed/fixed in rhel8.2
