This subcommand is used to zap lvs, partitions or raw devices that have been used
|
2017-10-24 15:13:40 +00:00
|
|
|
by ceph OSDs so that they may be reused. If given a path to a logical
|
|
|
|
|
volume it must be in the format of vg/lv. Any filesystems present
|
|
|
|
|
on the given lv or partition will be removed and all data will be purged.
|
|
|
|
|
|
|
|
|
|
.. note:: The lv or partition will be kept intact.

.. note:: If the logical volume, raw device or partition is being used for any ceph related
|
|
|
|
|
mount points they will be unmounted.

Zapping a logical volume::
|
|
|
|
|
|
|
|
|
|
ceph-volume lvm zap {vg name/lv name}
|
|
|
|
|
|
|
|
|
|
Zapping a partition::
|
|
|
|
|
|
|
|
|
|
ceph-volume lvm zap /dev/sdc1

|
|
|
|
|
If you are zapping a raw device or partition and would like any vgs or lvs created
|
|
|
|
|
from that device removed use the ``--destroy`` flag. A common use case is to simply
|
|
|
|
|
deploy OSDs using a whole raw device. If you do so and then wish to reuse that device for
|
|
|
|
|
another OSD you must use the ``--destroy`` flag when zapping so that the vgs and lvs that
|
|
|
|
|
ceph-volume created on the raw device will be removed.
|
|
|
|
|
|
|
|
|
|
Zapping a raw device and destroying any vgs or lvs present::
|
|
|
|
|
|
|
|
|
|
ceph-volume lvm zap /dev/sdc --destroy
|
