# Uncomment the first line (VGCHANGE=”vgchange -a e -q n”), and comment
# out the default, if you want to activate volume groups in exclusive mode
# and ignore the disk quorum requirement. Since the disk quorum ensures
# the integrity of the LVM configuration, it is normally not advisable
# to override the quorum.
#
# Uncomment the second line (VGCHANGE=”vgchange -a e -q n -s”), and comment
# out the default, if you want to activate volume groups in exclusive mode,
# ignore the disk quorum requirement, and disable the mirror
# resynchronization. Note it is normally not advisable to override the
# quorum.
#
# Uncomment the third line (VGCHANGE=”vgchange -a s”) and comment
# out the default, if you want volume groups activated in shared mode.
# This assumes the volume groups have already been marked as sharable
# and a part of a Serviceguard cluster with 'vgchange -c y -S y'.
#
# Uncomment the fourth line (VGCHANGE=”vgchange -a s -q n”), and comment
# out the default, if you want to activate volume groups in shared mode
# and ignore the disk quorum requirement. Note it is normally not
# advisable to override the quorum.
#
# Uncomment the fifth line (VGCHANGE=”vgchange -a y”) if you wish to
# use non-exclusive activation mode. Single node cluster configurations
# must use non-exclusive activation.
