# This is a local configuration file template for the LVM2 system
|
|
# which should be installed as @DEFAULT_SYS_DIR@/lvmlocal.conf .
|
|
#
|
|
# This file allows you to assign a unique identity to a host running
|
|
# LVM2 that is permitted to access storage devices visible to more than
|
|
# one machine simultaneously.
|
|
#
|
|
# You must ensure that every such host uses a different system_id
|
|
# identifier, otherwise LVM2 cannot protect you from simultaneous
|
|
# access from multiple hosts and possible data corruption.
|
|
#
|
|
# Refer to 'man lvmsystemid' for information about the correct ways
|
|
# to use this and its limitations.
|
|
#
|
|
# 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 to avoid accidentally assigning the same system ID to
|
|
# more than one host!
|
|
|

|
|
# when global/system_id_source is set to "lvmlocal" in the main
|
|
# configuration file, conventionally @DEFAULT_SYS_DIR@/lvm.conf.
|
|
# When used, it must be set to a unique value - often a hostname -
|
|
# across all the hosts sharing access to the storage.

|
|
# system_id that the local host is allowed to access. These are

|
# used for all values of global/system_id_source except "none".
