# Unable to Create Volume From Image

## Problem

Unable to create volume from image on the Cinder host. The below error is observed on the cinder host in */var/log/pf9/cindervolume-base.log.*

{% tabs %}
{% tab title="None" %}

```none
ERROR oslo_messaging.rpc.server ImageTooBig: Image [image-id] size exceeded available disk space: There is no space to convert image. Requested: [size in bytes], available: [size in bytes]
```

{% endtab %}
{% endtabs %}

## Environment

* Platform9 Managed OpenStack - All Versions
* Cinder
* Glance

## Cause

Unable to create the volume from image due to low free disk space on the Cinder host.

## Diagnostics

* Get the information of the Cinder host on which the volume was created by running below command.

{% tabs %}
{% tab title="None" %}

```none
$ openstack volume show [volume-id]
```

{% endtab %}
{% endtabs %}

* On the Cinder host check the log file */var/log/pf9/cindervolume-base.log* for ***volume-id*** for below error message.

{% tabs %}
{% tab title="None" %}

```none
ERROR oslo_messaging.rpc.server ImageTooBig: Image [image-id] size exceeded available disk space: There is no space to convert image. Requested: [size in bytes], available: [size in bytes]
```

{% endtab %}
{% endtabs %}

* Check if the ***image\_conversion\_dir*** is defined in the cinder configuration. You can check it in the below two files.
  * */opt/pf9/etc/pf9-cindervolume-base/conf.d/cinder.conf*
  * */opt/pf9/etc/pf9-cindervolume-base/conf.d/cinder\_override.conf*
* If not, the system will be using the default path for the temporary image conversions which is *$state\_path/conversion* and can be confirmed from the above two configuration files.
* Next, check if the mount point on which ***image\_conversion\_dir*** is present has enough free disk space to store the image at the time of conversion.

## Resolution

We can resolve the issue using below two workarounds.

1. Add more storage to the mount point on which ***image\_conversion\_dir*** is located.

OR

1. Add the Image conversion directory path with enough storage in default section of the file */opt/pf9/etc/pf9-cindervolume-base/conf.d/cinder\_override.conf* on cinder hosts.

Example:

{% tabs %}
{% tab title="None" %}

```none
# vi /opt/pf9/etc/pf9-cindervolume-base/conf.d/cinder_override.conf
[DEFAULT]
..
image_conversion_dir=/preferred/path/for/disk/conversion
..
```

{% endtab %}
{% endtabs %}

2. Restart service ***pf9-cindervolume-base*** on the Cinder host to make the change in configuration file effective.

## Additional Information

For more details on the Cinder configuration, please refer to the OpenStack documentation for [Cinder](https://docs.openstack.org/cinder/queens/configuration/block-storage/samples/cinder.conf.html).
