# High Load on the Ceph Cluster Being Used for Cinder

## Problem

You are observing increased *IOPS* to the *Ceph* clusters especially for the *Cinder* pool.

## Environment

* Platform9 Managed OpenStack - All Versions

## Cause

*Cinder* queries the *Ceph* cluster periodically to gather data regarding the *Cinder* backends, *volumes* and the *snapshots* present on the *Cinder\_\_pool*.

## Resolution

1. Add the `rbd_exclusive_cinder_pool` property to the *cinder\_override.conf* file across all your Cinder hosts. This property needs to be added to the backend configuration stanza.

```javascript
pf9@test ~ $ cat /opt/pf9/etc/pf9-cindervolume-base/conf.d/cinder_override.conf
[DEFAULT]
enabled_backends  =  ceph
glance_api_version  =  2

[ceph]
volume_backend_name  =  ceph1
volume_driver  =  cinder.volume.drivers.rbd.RBDDriver
rbd_exclusive_cinder_pool = true
```

2. Restart the *pf9-cindervolume-base* service for the changes to take effect

{% tabs %}
{% tab title="Javascript" %}

```javascript
pf9@test ~ $ systemctl restart pf9-cindervolume-base
```

{% endtab %}
{% endtabs %}

## Additional Information

The value for the property is going to be set to True by default starting with the Wallaby release as per the [OpenStack release notes](https://docs.openstack.org/releasenotes/cinder/wallaby.html).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://platform9.com/kb/pmo/solution/high-load-on-the-ceph-cluster-for-cinder-pool.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
