+ # (all copies made the same) every time a machine reboots or crashes.
+ #
+ # In the event of a failure, the specified policy will be used to
+ # determine what happens:
+ #
+ # "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.
+ # Currently this is not implemented properly and behaves
+ # similarly to:
+ #
+ # "allocate_anywhere" - Operates like "allocate", but it does not
+ # require that the new space being allocated be on a
+ # device is not part of the mirror. For a log device
+ # failure, this could mean that the log is allocated on
+ # the same device as a mirror device. For a mirror
+ # device, this could mean that the mirror device is
+ # allocated on the same device as another mirror device.
+ # This policy would not be wise for mirror devices
+ # because 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 replacement.
