Ansible “msg”: “Failed to find required executable pvs”

I’m using the following in Ansible 2.1 on OSX and getting the subject message:

lvg: vg=vgname pvs=pvname state=present

Bug? or what am I doing wrong.

This syntax was working OK with ansible 1.9.1

The syntax is fine.
The messages say it can't find the executable pvs. Do the target host have lvm installed?

I must have missed the fact that lvm2 didn’t get installed. Thanks!
