Line 9: On current Fedora lvm version, lvm uses the lvmetad daemon, which cause
Line 10: some vdsm lvm queries to return incorrect data. This patch uses vdsm
Line 11: private configuration to disable usage of lvmetad.
I don't claim to understand the issue, but the following line in in lvm.conf(5) seems ominous, and suggests that we may need to either integrate with lvmetad or conflict with its running:

 and started again afterwards.
