I'm installing block storage node in my OpenStack infrastructure and couldn't understand how to properly configure filters in lvm.conf. I'm installing Ocata release using this guide, the LVM config part is quite confusing. As far as I understood I should filter certain physical volumes to avoid LVM scanning both on host and guest OS.
Lets say I have following PV-s: /dev/md2p1 for OS, and /dev/md2p2 for cinder. How should I:
- Configure filters in lvm.conf on host OS?
- Configure filters in lvm.conf on guest OS?
