Cloning a volume

You can create a clone of a volume to make a point-in-time copy of the data. When you clone a volume, the system creates a snapshot of the volume and then creates a copy of the data referenced by the snapshot. This is an asynchronous process, and the amount of time the process requires depends on the size of the volume you are cloning and the current cluster load.

Before you begin

About this task

The cluster supports up to two running clone requests per volume at a time and up to 8 active volume clone operations at a time. Requests beyond these limits are queued for later processing.
Note: Cloned volumes do not inherit volume access group membership from the source volume.

Steps

  1. Select NetApp Element Management > Management.
    Note: If two or more clusters are added, ensure that the cluster you intend to use for the task is selected in the navigation bar.
  2. Click the Volumes sub-tab.
  3. From the Active view, select the check box for the volume you want to clone.
  4. Click Actions.
  5. In the resulting menu, click Clone.
  6. In the Clone Volume dialog box, enter a volume name for the newly cloned volume.
    Tip: Use descriptive naming best practices. This is especially important if multiple clusters or vCenter Servers are used in your environment.
  7. Select a size in GB or GIB for the cloned volume.
    Note: The default volume size selection is in GB. You can create volumes using sizes measured in GB or GiB:
    • 1GB = 1 000 000 000 bytes
    • 1GiB = 1 073 741 824 bytes
    Note: Increasing the volume size of a clone results in a new volume with additional free space at the end of the volume. Depending on how you use the volume, you may need to extend partitions or create new partitions in the free space to make use of it.
  8. Select an account to associate with the newly cloned volume.
  9. Select the one of the following access types for the newly cloned volume:
    • Read/Write
    • Read Only
    • Locked
  10. Adjust 512e settings, if required.
    Note:
    • By default, 512 byte emulation is enabled for all new volumes.
    • VMware requires 512e for disk resources. If 512e is not enabled, a VMFS cannot be created and volume details are grayed out.
  11. Click OK.
    Note: The time to complete a cloning operation is affected by volume size and current cluster load. Refresh the page if the cloned volume does not appear in the volume list.
