Creating a Block Volume
Create a block volume in the Block Volume service.
Open the navigation menu and click Storage. Under Block Storage, click Block Volumes.
Click Create Block Volume.
In the Create block volume, provide the following values:
- Name: Enter a user-friendly name for the volume. Avoid entering confidential information.
- Create in compartment: Select the compartment to create the volume in, if different from the current compartment.
- Availability Domain: Select the same availability domain as the instance you plan to attach the volume to.
- Volume size and performance: Select Default or
Custom. If you select Custom, enter
the following values
- Volume size: Enter the size of the volume, be between 50 GB and 32 TB. You can choose in 1 GB increments within this range. The default size is 1024 GB. If you choose a size outside of your service limit, you might be prompted to request an increase. See Service Limits.
- Volume target performance: Optionally, you can select the appropriate performance level for your requirements. For more information about volume performance options, see Block Volume Performance. The default option is Balanced.
- Backup policies: Optionally, select the appropriate backup policy for your requirements. See Policy-Based Backups.
- Cross region replication: Optionally, enable asynchronous cross-region replication for the volume. See Replicating a Volume.
Encryption: Optionally, encrypt the data in this volume by using your own Vault encryption key. Select Encrypt using customer-managed keys, and then select the vault compartment and vault that contain the master encryption key you want to use. Then, select the master encryption key compartment and master encryption key.Important
The Block Volume service doesn't support encrypting volumes with keys that are encrypted using the Rivest-Shamir-Adleman (RSA) algorithm. When you use your own keys, you must use keys that are encrypted using the Advanced Encryption Standard (AES) algorithm. This restriction applies to block volumes and boot volumes.
Click Show Tagging Options to add tags to the volume. If you have permissions to create a resource, then you also have permissions to apply free-form tags to that resource. To apply a defined tag, you must have permissions to use the tag namespace. For more information about tagging, see Resource Tags. If you're not sure whether to apply tags, skip this option (you can apply tags later) or ask an administrator.
Click Create Block Volume.
The block volume details page opens, and the volume is in the Provisioning state. When the state changes to Available, the volume is ready to attach to an instance. For more information, see Attaching a Block Volume to an Instance.
Run the CreateVolume operation to create block volume.
