# 'mirror_segtype_default' defines which segtype will be used when the
# shorthand '-m' option is used for mirroring. The possible options are:
#
# "mirror" - The original RAID1 implementation provided by LVM2/DM. It is
# characterized by a flexible log solution (core, disk, mirrored)
# and by the necessity to block I/O while reconfiguring in the
# event of a failure. Snapshots of this type of RAID1 can be
# problematic.
#
# "raid1" - This implementation leverages MD's RAID1 personality through
# device-mapper. It is characterized by a lack of log options.
# (A log is always allocated for every device and they are placed
# on the same device as the image - no separate devices are
# required.) This mirror implementation does not require I/O
# to be blocked in the kernel in the event of a failure.
