This message/failure was the fix for raid1|10 volumes when attempting to create volumes using 100%FREE on top of varying sized PVs. This was the fix for these two bugs:
https://issues.redhat.com/browse/RHEL-8377
https://issues.redhat.com/browse/RHEL-8334
When testing this fix, it was tried on raid4,5,6 to ensure those still worked due to them not requiring mirror redundancy. However, this was just recently tried using raid0 and raid0_meta, which should behave just like the other striped raid types, but they don't.
