This is strange, because lvcreate -v -v writes something like
Duplicate PV R9n6ygz1oDeeOQWQH9vPFWCVirNSQ9rr on /dev/sda4 - using md /dev/md5
which looks as if lvcreate knows that it has to use md5 instead of sda4.

Yes, this fixed the problem (tested both on V1 and V2 metadata).
Thanks for a hint!

Any compiler or language that likes to hide things like memory allocations
behind your back just isn't a good choice for a kernel. --Linus Torvalds
