...also there's the activation/auto_set_activation_skip
setting in lvm.conf to enable or disable this automatic
skipping of certain LVs on activation (there's a short
comment above that setting that explains it). This setting
is enabled by default.

See also lvcreate/vgchange/lvchange man pages and the documentation
for "-K/--ignoreactivationskip" and "-k/--setactivationskip {y|n}" options.
