# These directories must not be on logical volumes!

# It's possible to use LVM2 with a couple of directories here,

# preferably on different (non-LV) filesystems, and with no other

# on-disk metadata (pvmetadatacopies = 0). Or this can be in

# addition to on-disk metadata areas.

# The feature was originally added to simplify testing and is not

# supported under low memory situations - the machine could lock up.

# Never edit any files in these directories by hand unless you

# you are absolutely sure you know what you are doing! Use

# the supplied toolset to make changes (e.g. vgcfgrestore).

# dirs = [ "/etc/lvm/metadata", "/mnt/disk2/lvm/metadata2" ]

# mirror_library is the library used when monitoring a mirror device.

# It removes failed devices from a volume group and reconfigures a

# mirror as necessary.
