Re: [ovirt-users] LVM structure
Sure. vdsm-tool should be disabling lvmetad on the host automatically.
Maybe some of the hosts were fresh installed and others have been upgraded
from older versions? In any case, you should be able to run on any host in
maintenance mode:
sudo vdsm-tool configure --force
And this should edit the lvm.conf file to disable lvmetad globally and also
prevent the lvmetad service from starting.

OK.
Is it worth trying to understand why amongst our 32 hosts in 2 DC, all in
the same version (OS, vdsm, qemu packages...) some are showing they're
using lvmetad and some not?
