You can now leverage a powerful and differentiating feature from Oracle Cloud Infrastructure to manage multiple block storage volumes and boot volumes more quickly and easily. In May 2018, we introduced our volume groups feature, which enables you to streamline the creation and management of groups of block volumes by using the CLI, SDK, and Terraform. The ability to manage volume groups is ideal for the protection and lifecycle management of enterprise applications, which typically require multiple volumes across multiple compute instances to function effectively. We are now extending our volume group feature to the web-based Oracle Cloud Infrastructure Console.
With volume groups, you can manage petabytes of cloud block storage in a crash-consistent, coordinated manner in seconds and in just a few clicks. You can create groups of your volumes, back up volume groups, restore from volume group backups, and create deep disk-to-disk clones of volume groups, all within a few seconds. That includes the boot volumes for your compute instances and all your storage volumes for crash-consistent instance disaster recovery or environment duplication and expansion.
A single volume group can have up to 128 TB of storage and 32 volumes. If you need to manage more storage space, you can create multiple volume groups. Because the solution is scalable, you can start with a small storage allocation. As your business demand grows, you can add more volumes and groups, and combine that with the offline resize feature, to easily scale and manage petabytes of storage by using the Oracle Cloud Infrastructure Block Volumes service.
With this feature update, we are also improving the policies that control the volume group operations. You now have the ability to manage more granular permissions by separating volume group permissions from other volume operations. For details, see the Block Volumes service documentation on policies.
This feature is free of charge and is available in all regions. You pay only for the amount of provisioned storage using the Oracle Cloud Infrastructure storage pricing.
The following sections show how to use the volume group functionality in the Oracle Cloud Infrastructure Console.
From the navigation menu, select Block Storage, select Volume Groups, and then click Create Volume Group.
Enter a name for the volume group, and select and add the volumes to place in it. You can add boot volumes for your compute instances and block volumes.
Click Create Volume Group. The volume group is created in seconds.
From the volume group's details page, you can add volumes to the group by clicking Add Block Volume or Add Boot Volume. You can remove a volume by clicking the Actions menu (three dots) for the volume and selecting Remove.
From the Actions menu for the volume group, select Create Volume Group Backup.
Enter a name for the volume group backup, and then click Create.
From the Actions menu for the volume group backup, select Create Volume Group.
From the Actions menu for the volume group, select Create Volume Group Clone.
After entering a name for the clone, click Create.
The cloned volume group and the cloned volumes in it become available within seconds.
The Oracle Cloud Infrastructure Console provides a straightforward and simple way to create and manage volume groups. You can perform a crash-consistent, coordinated backup of a group of volumes, and restore from those backups in a few clicks. You can also create crash-consistent, coordinated, deep disk-to-disk volume group clones. The clones become available in seconds, and they are completely isolated from the source volume group and the volumes in it. You can use volume group clones to duplicate your entire instance OS boot disk and block storage for production troubleshooting, dev/test, and UAT/QA purposes.
