+    # A disk log ensures that a mirror does not need to be re-synced
+    # (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.
