.. _ceph-volume-lvm-zap:
``zap``
=======
This subcommand is used to zap lvs or partitions that have been used
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.
Zapping a logical volume::
ceph-volume lvm zap {vg name/lv name}
Zapping a partition::
ceph-volume lvm zap /dev/sdc1
