Prerequisites
A subsystem (block-enabled view). See Creating a Block Storage Subsystem (View).
Creating Volumes Using the VAST Web UI
Navigate to the Volumes tab in the Element Store page.
Note
The Volumes and Hosts tabs appear only when there is at least one block-enabled view configured on the cluster.
Click Create Volume.
Select either Single volume to create one volume or Multiple volumes to create multiple volumes of the same size with the same name suffix.
If you selected Single volume, complete these fields:
Tenant
Select the tenant, if applicable (if the cluster has more than one tenant that has block-enabled views configured).
View
Select the block enabled view (subsystem) on which you want to provision the volume.
Name
Enter a path to the volume relative to the subsystem directory. The path should not begin with a slash ("/"). You can include slashes inside the path to indicate a hierarchy of directories. The path will be created under the subsystem path for the volume. Any directory hierarchy indicated by slashes will be created accordingly. For example, if you specify
b/c/dthe directories<subsystem_path>/band<subsystem_path>b/cwill be created if they do not yet exist, as well as the new directory<subsystem_path>/b/c/d.Capacity
Enter number and select GB or TB from the dropdown.
Supported range: 1 GB - 1000 TB.
If you selected Multiple volumes, complete these fields:
Tenant
Select the tenant on which the subsystem under which you want to create a volume resides, if applicable.
View
Select the block-enabled view (subsystem) on which you want to provision the volumes.
Name
Enter a path to each volume including a base volume name. The path is relative to the subsystem directory. The path should not begin with a slash ("/"). You can include slashes to indicate a directory hierarchy. A path will be created under the subsystem path for each volume. Any directory hierarchy indicated by slashes will be created accordingly. For example, if you specify
b/c/dthe directories<subsystem_path>/band<subsystem_path>b/cwill be created if they do not yet exist, as well as the new directory<subsystem_path>/b/c/d.See also Suffix.
Capacity
Enter number and select GB or TB from the dropdown.
Supported range: 1 GB - 1000 TB.
Suffix
Optionally enter a suffix to be appended to the name for each volume. An incremental digit will also be added to each volume name.
Count
Enter the number of volumes you want to create.
In the Tags section, optionally add tags in the format key=value. These are applied to the volume(s) and can be used to add identifying information for organizational purposes. Hosts can also be tagged. You can also add tags later by modifying each volume.
To enter a tag, enter the key string in the Key field and the value string in the Value field, and then click Add Tag. Repeat as needed to add more tags.
Click Create.
Volume creation begins and can be monitored in the Activities page.
The volumes are listed in the Volumes tab.
If you created multiple volumes, a progress dialog appears showing you the progress of volume creation. You can either leave it open, in which case it will show the progress and let you know when the task is done, or click one of the other options provided:
Go to activities, to monitor the process from the Activities page.
Go to Volumes Table, to go back to the Volumes tab. The new volumes will be added to the table as they are created.
If you leave it open, when the task is done, another option, Map To Volumes Table, appears. You can click this option to configure mappings of the volumes to hosts.
Creating a Volume Using the VAST CLI
To create a volume using the VAST CLI, use the volume create command.
