lvm: Add vdsm local lvm configuration
Add lvmlocal.conf with vdsm specific configuration:
- devices/global_filter - filter out ovirt lvs from all lvm commands on
the host.
This change is expected to prevent discovery and auto-activation of
guest lvs on raw ovirt volumes. This problem is causing performance
issues and may lead to data corruption.
This change does not effect discovery and auto-activation of guest lvs
on direct luns. There is no way vdsm can filter direct since we don't
know which luns should be filtered.
- global/use_lvmetad - disable lvmetad usage in lvm commands
This first comments on the file contains vdsm metadata, used by vdsm
during upgrades. The default configuration looks like this:
#REVISION: 1
#PRIVATE: NO
With this configuration, vdsm will upgrade this file when running:
vdsm-tool configure --module lvm
To control the local lvm configuration, the system administrator can
mark the file as private by modifying this line:
#PRIVATE: YES
If the file is private, vdsm will never upgrade the file.
The vdsm metadata header starts at the first line and ends on the first
non-comment line.
This patch adds the default configuration.
