You can use:
lvmconfig --withcomments devices/global_filter

to see what LVM sees:
> global_filter=["r|/dev/zd.*|","r|/dev/mapper/pve-.*|","r|/dev/mapper/.*-(vm|base)--[0-9]+--disk--[0-9]+|"]

So this is OK. I avoid touching /etc files during stable updates, so the
fix for this will have to wait for the next major release as it's cosmetic
only.

Thanks for noticing.

cheers,
