New Volume Dialog

The New Volume dialog lets you create a new volume.

For mirror volumes, the Snapshot Scheduling section is replaced with a section called Mirror Scheduling:

The Volume Setup section specifies basic information about the volume using the following fields:

  • Volume Type - a standard volume, or a local or remote mirror volume
  • Volume Name (required) - a name for the new volume
  • Mount Path - a path on which to mount the volume (check the small box at the right to indicate the mount path for the new volume; if the box is not checked, an unmounted volume is created)
  • Topology - the new volume's rack topology
  • Read-only - if checked, prevents writes to the volume

The Permissions section lets you grant specific permissions on the volume to certain users or groups:

  • User/Group field - the user or group to which permissions are to be granted (one user or group per row)
  • Permissions field - the permissions to grant to the user or group (see the Permissions table below)
  • Delete button ( ) - deletes the current row
  • [+ Add Permission ] - adds a new row

Usage Tracking

The Usage Tracking section displays cluster usage and sets quotas for the volume using the following fields:

Quotas - the volume quotas:

  • Volume Advisory Quota - if selected, enter the advisory quota for the volume expressed as an integer plus the single letter abbreviation for the unit (such as 100G for 100GB). When this quota is reached, an advisory email is sent to the user or group.
  • Volume Hard Quota - if selected, enter the maximum limit for the volume expressed as an integer plus the single letter abbreviation for the unit (such as 128G for 128GB). When this hard limit is reached, no more data is written to the volume.

Replication Section

The Replication section contains the following fields:

  • Replication - the requested replication factor for the volume
  • Min Replication - the minimum replication factor for the volume. When the number of replicas drops down to or below this number, the volume is aggressively re-replicated to bring it above the minimum replication factor.
  • Optimize Replication For - the basis for choosing the optimum replication factor (high throughput or low latency)

Snapshot Scheduling Section

The Snapshot Scheduling section (normal volumes) contains the snapshot schedule, which determines when snapshots will be automatically created. Select an existing schedule from the pop-up menu.

The Mirror Scheduling section (local and remote mirror volumes) contains the mirror schedule, which determines when mirror volumes will be automatically created. Select an existing schedule from the pop-up menu.

Buttons:

  • OK - creates the new volume
  • Cancel - exits without creating the volume
