Destroying Ceph OSDs
--------------------
To remove an OSD via the GUI first select a {PVE} node in the tree view and go
to the **Ceph -> OSD** panel. Select the OSD to destroy. Next click the **OUT**
button. Once the OSD status changed from `in` to `out` click the **STOP**
button. As soon as the status changed from `up` to `down` select **Destroy**
from the `More` drop-down menu.
To remove an OSD via the CLI run the following commands.
[source,bash]
----
ceph osd out <ID>
systemctl stop ceph-osd@<ID>.service
----
NOTE: The first command instructs Ceph not to include the OSD in the data
distribution. The second command stops the OSD service. Until this time, no
data is lost.
The following command destroys the OSD. Specify the '-cleanup' option to
additionally destroy the partition table.
[source,bash]
----
pveceph osd destroy <ID>
----
WARNING: The above command will destroy data on the disk!
