Appendix B. The LVM Configuration Files
76
#
# Refer to 'man lvm.conf' for further information including the file
layout.
#
# To put this file in a different directory and override /etc/lvm set
# the environment variable LVM_SYSTEM_DIR before running the tools.
# This section allows you to configure which block devices should
# be used by the LVM system.
devices {
# Where do you want your volume groups to appear ?
dir = "/dev"
# An array of directories that contain the device nodes you wish
# to use with LVM2.
scan = [ "/dev" ]
# A filter that tells LVM2 to only use a restricted set of devices.
# The filter consists of an array of regular expressions. These
# expressions can be delimited by a character of your choice, and
# prefixed with either an 'a' (for accept) or 'r' (for reject).
# The first expression found to match a device name determines if
# the device will be accepted or rejected (ignored). Devices that
# don't match any patterns are accepted.
# Be careful if there there are symbolic links or multiple filesystem
# entries for the same device as each name is checked separately
against
# the list of patterns. The effect is that if any name matches any
'a'
# pattern, the device is accepted; otherwise if any name matches any
'r'
# pattern it is rejected; otherwise it is accepted.
# Don't have more than one filter line active at once: only one gets
used.
# Run vgscan after you change this parameter to ensure that
# the cache file gets regenerated (see below).
# If it doesn't do what you expect, check the output of 'vgscan -
vvvv'.
# By default we accept every block device:
# Steel Toe installed filter -- use this line while running tests
filter = [ "r/hda/", "r/disk/", "a/.*/" ]
# Steel Toe installed filter -- use this line when installing new
kernels
#filter = [ "r/disk/", "a/.*/" ]
