# The default metadata format that commands should use - "lvm1" or "lvm2".
# The command line override is -M1 or -M2.
# Defaults to "lvm1" if compiled in, else "lvm2".
# format = "lvm1"
# Location of proc filesystem
proc = "/proc"
# Type of locking to use. Defaults to local file-based locking (1).
# Turn locking off by setting to 0 (dangerous: risks metadata corruption
# if LVM2 commands get run concurrently).
# Type 2 uses the external shared library locking_library.
# Type 3 uses built-in clustered locking.
locking_type = 1
# If using external locking (type 2) and initialisation fails,
# with this set to 1 an attempt will be made to use the built-in
# clustered locking.
# If you are using a customised locking_library you should set this to 0.
fallback_to_clustered_locking = 1
# If an attempt to initialise type 2 or type 3 locking failed, perhaps
# because cluster components such as clvmd are not running, with this set
# to 1 an attempt will be made to use local file-based locking (type 1).
# If this succeeds, only commands against local volume groups will proceed.
# Volume Groups marked as clustered will be ignored.

# in progress. A directory like /tmp that may get wiped on reboot is OK.
