   6 This subcommand is used to zap lvs, partitions or raw devices that have been used
   7 by ceph OSDs so that they may be reused. If given a path to a logical
   8 volume it must be in the format of vg/lv. Any filesystems present
   9 on the given lv or partition will be removed and all data will be purged.
  10
  11 .. note:: The lv or partition will be kept intact.
  12
  13 .. note:: If the logical volume, raw device or partition is being used for any ceph related
  14           mount points they will be unmounted.
  15
  16 Zapping a logical volume::
  17
  18       ceph-volume lvm zap {vg name/lv name}
  19
  20 Zapping a partition::
  21
  22       ceph-volume lvm zap /dev/sdc1
  23
  24 If you are zapping a raw device or partition and would like any vgs or lvs created
  25 from that device removed use the ``--destroy`` flag. A common use case is to simply
  26 deploy OSDs using a whole raw device. If you do so and then wish to reuse that device for
  27 another OSD you must use the ``--destroy`` flag when zapping so that the vgs and lvs that
  28 ceph-volume created on the raw device will be removed.

  30 Zapping a raw device and destroying any vgs or lvs present::
  31
  32       ceph-volume lvm zap /dev/sdc --destroy
