Instructions

Click the name of your service in the list. The Overview tab displays the General information of your service (including its Identifier and IP address), its Service configuration and its Subscription.

To act on an existing volume, open the Volumes tab, tick the box of the volume concerned, then open the Actions menu.

Creating a partition

To add a new partition, open the Volumes tab and click Create a volume.

Enter the Volume name, the Size (GB), an optional Description and the authorised Protocol (NFS, CIFS (SMB) or NFS + CIFS), then click Create a volume.

Modifying the size of a partition

To change the size of a partition, tick the box of the volume concerned, then click Actions and Edit size.

Enter the New size, then click Apply.

Change the frequency of snapshots

By default, a snapshot of your NAS content takes place every hour, and is saved on your NAS.

However, you can enable additional snapshots at different frequencies if you wish, which will also be saved on your NAS.

To do this, tick the box of the volume concerned, then click Actions and Manage snapshots. In the Snapshot policies tab of the volume, click Manage snapshot frequencies in the Automatic snapshots section.

Tick the frequencies to enable, then click Save changes.

Creating an instant snapshot

Apart from the snapshots taken automatically, you can create an instant snapshot of a partition at any time. In the Snapshot policies tab of the volume, click Take a snapshot in the Manual snapshots section.

Enter a Snapshot suffix (your snapshot will be named snap-<volume name>-<your suffix>) and click Take a snapshot.

To delete manual snapshots, tick them in the Manual snapshots list, click Delete, then confirm.

Adding an access

In order to access the partition you created earlier, you will need to configure access.

To authorise an IP to access the NAS, tick the box of the volume concerned, then click Actions and Manage access. The Access control (ACL) tab of the volume opens.

Then click Add an access, and select the IP address or IP block of your OVHcloud product in the IP field.

You must also define in Type whether the authorised access for this IP address is Read only or Read/write. Then click Add an access.

Deleting an access

To remove access to a partition, tick the IP address concerned in the Access control (ACL) tab of the volume, click Delete, then Delete access.

ZFS settings

To change the ZFS settings of a partition, tick the box of the volume concerned, then click Actions and Configure usage (ZFS).

In Select template, apply a usage template suited to your workload (Default, Virtual machines, Databases or File systems (large files)), or choose Custom to set the atime, recordsize and sync values yourself. Then click Edit settings.

For details on each setting and the values applied by each template, read our guide on configuring the ZFS settings of a partition.
