Comment # 27 on bug 878473 from Liuhua Wang

This bug is because when use-lvmetad=1 we need lvm2-lvmetad.service run to
activate lvm partition. But in opensuse13.1 lvm2-lvmetad.socket is not enabled. 

The problem is resolved in opensuse13.2, because opensuse13.2 have "enable
lvm2-lvmetad.socket" in systemd-presets-branding-openSUSE.
#grep lvm /usr/lib/systemd/system-preset/90-default-openSUSE.preset
  enable lvm2-lvmetad.socket
  enable lvm2-lvmetad.service

Though there is not need to enable lvm2-lvmetad.service, which will cause
lvm2-lvmetad.service running no matter use_lvmetad=0 or 1 and so there will be
warning message. (see bnc#901859)

So I think as to this bug we can close it as resolved.
