# If no preferred name matches, or if preferred_names are not defined,
# the following built-in preferences are applied in order until one
# produces a preferred name:
# Prefer names with path prefixes in the order of:
# /dev/mapper, /dev/disk, /dev/dm-*, /dev/block.
# Prefer the name with the least number of slashes.
# Prefer a name that is a symlink.

# This configuration option does not have a default value defined.
# Configuration option devices/filter.
# Limit the block devices that are used by LVM commands.
# This is a list of regular expressions used to accept or reject block
# device path names. Each regex is delimited by a vertical bar '|'
# (or any character) and is preceded by 'a' to accept the path, or
# by 'r' to reject the path. The first regex in the list to match the
# path is used, producing the 'a' or 'r' result for the device.
# When multiple path names exist for a block device, if any path name
# matches an 'a' pattern before an 'r' pattern, then the device is
# accepted. If all the path names match an 'r' pattern first, then the
# device is rejected. Unmatching path names do not affect the accept
# or reject decision. If no path names for a device match a pattern,
# then the device is accepted. Be careful mixing 'a' and 'r' patterns,
# as the combination might produce unexpected results (test changes.)
# Run vgscan after changing the filter to regenerate the cache.

# mirror LVs. If this setting is disabled, allowing mirror LVs to be
# scanned, it may cause LVM processes and I/O to the mirror to become
# blocked. This is due to the way that the mirror segment type handles
# failures. In order for the hang to occur, an LVM command must be run
# just after a failure and before the automatic LVM repair process
# takes place, or there must be failures in multiple mirrors in the
# same VG at the same time with write failures occurring moments before

# underlying storage, the choice has minimal consequence. If the

# existing LV. If there is insufficient space and a list of tags is
# defined here, it will check whether any of them are attached to the
# PVs concerned and then seek to match those PV tags between existing
# extents and new extents.

# Use the special tag "@*" as a wildcard to match any PV tag:
# cling_tag_list = [ "@*" ]
# LVs are mirrored between two sites within a single VG, and

# and positions of signatures within the whole LV. It provides a
# cleaner LV after creation as all known signatures are wiped. The LV
# is not claimed incorrectly by other tools because of old signatures
# from previous use. The number of signatures that LVM can detect
# depends on the detection code that is selected (see

# device and they are placed on the same device as the image,
# so no separate devices are required.) This mirror

# running), LVM commands fall back to scanning disks to obtain VG
# metadata. lvmetad is kept updated via udev rules which must be set
# up for LVM to work correctly. (The udev rules should be installed
# by default.) Without a proper udev setup, changes in the system's
# block device configuration will be unknown to LVM, and ignored
# until a manual 'pvscan --cache' is run. If lvmetad was running
# while use_lvmetad was disabled, it must be stopped, use_lvmetad
# enabled, and then started. When using lvmetad, LV activation is
# switched to an automatic, event-based mode. In this mode, LVs are
# activated based on incoming udev events that inform lvmetad when
# PVs appear on the system. When a VG is complete (all PVs present),
# it is auto-activated. The auto_activation_volume_list setting
# controls which LVs are auto-activated (all by default.)
# When lvmetad is updated (automatically by udev events, or directly
# by pvscan --cache), devices/filter is ignored and all devices are
# scanned by default. lvmetad always keeps unfiltered information
# which is provided to LVM commands. Each LVM command then filters
# based on devices/filter. This does not apply to other, non-regexp,
# filtering settings: component filters such as multipath and MD

# Automatic handling requires dmeventd to be monitoring the LV.
#
# Accepted values:
# remove
# Simply remove the faulty device and run without it. If the log
# device fails, the mirror would convert to using an in-memory log.
# This means the mirror will not remember its sync status across
# crashes/reboots and the entire mirror will be re-synced. If a
# mirror image fails, the mirror will convert to a non-mirrored
# device if there is only one remaining good copy.
# allocate
# Remove the faulty device and try to allocate space on a new
# device to be a replacement for the failed device. Using this
# policy for the log is fast and maintains the ability to remember
# sync state through crashes/reboots. Using this policy for a
# mirror device is slow, as it requires the mirror to resynchronize
# the devices, but it will preserve the mirror characteristic of
# the device. This policy acts like 'remove' if no suitable device
# and space can be allocated for the replacement.
# allocate_anywhere
# Not yet implemented. Useful to place the log device temporarily
# on the same physical volume as one of the mirror images. This
# policy is not recommended for mirror devices since it would break
# the redundant nature of the mirror. This policy acts like
# 'remove' if no suitable device and space can be allocated for the

# The host tag foo is given to all hosts, and the host tag
# bar is given to the hosts named machine1 and machine2.
