+Destroying Ceph OSDs
+--------------------
+
+[thumbnail="screenshot/gui-ceph-osd-destroy.png"]
+
+To remove an OSD on the GUI, go to a PVE host under **Ceph -> OSD** and select
+the OSD you want to destroy. Then click on the **OUT** button and once the OSD
+is out, on the **STOP** button. After the OSD is out & down, you can select
+**Destroy** from the More drop-down menu.
To remove an OSD via the GUI first select the {PVE} node in the tree
view. Select the **Ceph -> OSD** panel and select the OSD to destroy.
Next click the **OUT** button. Once the OSD's 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.
+
+On the CLI issue the commands below to destroy a running OSD.
To remove an OSD via the CLI run the following commands.
+
+The first command tells Ceph to not include the OSD in data distribution
+anymore. The second stops the OSD service. Up to this point no data is lost and
+if the wrong OSD was specified, it can be reverted.
# I would move this to the beginning of the chapter. Explaining the
involved steps like setting the OSD to out, then down / systemctl stop
and then destroying it because that information is relevant for both
variants (GUI/CLI).
+
+[source,bash]
+----
+ceph osd out <ID>
+systemctl stop ceph-osd@<ID>.service
+----
+
+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!
