- #
- # 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.
