Comment # 23 on bug 997637 from Neil Rickert

> pv_major:pv_minor should be replaced by PV's major and minor number

Oops.  Sorry about that.

Let's try again.

First, after a successful boot:
 ----
# systemctl status lvm2-lvmetad.service
��� lvm2-lvmetad.service - LVM2 metadata daemon
   Loaded: loaded (/usr/lib/systemd/system/lvm2-lvmetad.service; disabled;

And next, from emergency mode after a failed boot:

The first two boots tonight were successful.  The third went into emergency
mode over the LVM problem.
