Dear Bastian,
thanks for picking up on this. We've done some more research, and we now
believe the issue to be upstream, so we've opened a bug report directly with
lvm: https://github.com/lvmteam/lvm2/issues/104
If you check the lvm debug log we posted there, you'll see that it correctly
picks up the filter, finds and scans the right device (sda3), but then rejects
it since at the time of scanning,
/dev/disk/by-path/pci-0000:04:00.0-sas-phy0-lun-0-part3 (the one in the
filter) doesn't exist. This might be a race condition, since on some reboots
it sees part1 and part2, on some only part1, but never part3.
I could also reproduce the problem in Arch (Fedora, surprisingly, has too old
of an LVM version).
to your questions:

correct, but I don't think that's relevant any longer.

correct, I used bullseye's 69-lvm-metad.rules and renamed it to 69-lvm.rules
on bookworm.

again, I don't think it's relevant, but to help understand the situation
better:
