I'd like to avoid scanning LVs, and I thought I'd set global_filter

Hi Gordon, remove the last component in the filter: 'a|.*/|'.
Filters accept any device if any of it's "names" (all symbolic links) is
matched by an a pattern ("a|.*/|" in your case) and matches no previous
r pattern - for example anything in /dev/mapper/ is accepted.
When used as a blacklist filter(s) must contain only "r" paterns.
BTW it is usually better to use white list: list "a" patterns for all
disks you wish to accept and add "r|.*|" at the end.
