Wild guess here, you should try to set the "use_lvmetad" to 1
in /etc/lvm/lvm.conf and see if it helps.

For this issue I would suggest to install plymouth, it should
serialized the output on the console and allow you to have a better
idea of what's happening on the console.

See systemd.mount(5) manpage, there is a way to increase the timeout.

I guess you could write a .mount unit file if lvmetad is not helping,
you should be able to express dependencies there.
