lvm2/conf/lvmlocal.conf.in

# This is a local configuration file template for the LVM2 system
# which should be installed as @DEFAULT_SYS_DIR@/lvmlocal.conf .
#
# Refer to 'man lvm.conf' for information about the file layout.
#
# To put this file in a different directory and override
# @DEFAULT_SYS_DIR@ set the environment variable LVM_SYSTEM_DIR before
# running the tools.
#
# The lvmlocal.conf file is normally expected to contain only the
# "local" section which contains settings that should not be shared or
# repeated among different hosts.  (But if other sections are present,
# they *will* get processed.  Settings in this file override equivalent
# ones in lvm.conf and are in turn overridden by ones in any enabled
# lvm_<tag>.conf files.)
#
# Please take care that each setting only appears once if uncommenting
# example settings in this file and never copy this file between hosts.


# Configuration section local.
# LVM settings that are specific to the local host.
local {

	# Configuration option local/system_id.
	# Defines the local system ID for lvmlocal mode.
	# This is used when global/system_id_source is set to 'lvmlocal' in the
	# main configuration file, e.g. lvm.conf. When used, it must be set to
	# a unique value among all hosts sharing access to the storage,
	# e.g. a host name.
	#
	# Example
	# Set no system ID:
	# system_id = ""
	# Set the system_id to a specific name:
	# system_id = "host1"
	#
	# This configuration option has an automatic default value.
	# system_id = ""

	# Configuration option local/extra_system_ids.
	# A list of extra VG system IDs the local host can access.
	# VGs with the system IDs listed here (in addition to the host's own
	# system ID) can be fully accessed by the local host. (These are
	# system IDs that the host sees in VGs, not system IDs that identify
	# the local host, which is determined by system_id_source.)
	# Use this only after consulting 'man lvmsystemid' to be certain of
	# correct usage and possible dangers.
	# This configuration option does not have a default value defined.

	# Configuration option local/host_id.
	# The sanlock host_id used by lvmlockd. This must be unique among all the hosts
	# using shared VGs with sanlock. Accepted values are 1-2000, except when sanlock_align_size
	# is configured to 1, 2 or 4, which correspond to max host_id values of 250, 500, or 1000.
	# Applicable only if LVM is compiled with support for lvmlockd+sanlock.
	# This configuration option has an automatic default value.
	# host_id = 0
