[linux-lvm] auto_activation_volume_list in lvm.conf not honored

[Stefan Bauer]

Hi Peter,

as i said, we have master/slave setup _without_ concurrent write/read. So i do not see a reason why i should take care of locking as only one node is activating the volume group at the same time.

That should be fine - right?
