How do you resize a Volume?


ISSUE: How do you resize a Datakeeper Volume?

DataKeeper allows users to extend and shrink their DataKeeper volumes dynamically while retaining mirror settings. Once the resize is complete, a partial resync will be performed.

For extensive information regarding configurations, restrictions, and in-depth step-by-step instructions please refer to our Volume Resize documentation.

“Switchover Mirrors”, “Delete Job” and “Delete Mirror” are grayed out in the Action Panel


ISSUE: In the DataKeeper UI, “Switchover Mirrors”, “Delete Job” and “Delete Mirror” are grayed out in the Action Panel.

REASON: When a DataKeeper mirror is or becomes a part of a cluster/WSFC, all administration takes place at the WSFC level.

Steps to Remove:

In Failover Cluster Manager:

  1. From the Roles panel, select Storage and the related DataKeeper Volume.

  2. Right click and select Remove from the role you’ve created, then select Yes.

  3. From WFSC select Storage\Disk.

    The DataKeeper Volume is now listed as/Assigned To, Available Storage.

  4. Select Remove then select Yes.

    The DataKeeper Storage is no longer a resource in the cluster/WSFC.

  5. In the DataKeeper UI > Action Panel, select Delete Job. You will be prompted …“Are you sure you want to delete the ‘Volume (drive)’ and its mirror? Select Yes.

Preparing Storage for Datakeeper Usage


This video goes over the procedure for creating/preparing storage for Datakeeper usage. It also addresses creating a mirror between both Source and Target nodes.

For additional information regarding storage in conjuction with Datakeeper, please refer to our Most Common Storage Solutions and Creating a Mirror pages.

How to Relocate a Bitmap to Ephemeral Storage or a faster (SSD) drive


This video is an overview for Relocating a Bitmap to Ephemeral Storage or a faster (SSD) drive.

For additional information, please refer to our SIOS Datakeeper Intent Log or Relocation of Intent Log pages within our documentation.

Moving a Mirror From One Network to Another (Changing Mirror Endpoints)


The CHANGEMIRRORENDPOINTS command is used to move a DataKeeper protected volume to another network location. It only supports changing the endpoints of a mirrored volume that is configured on 3 nodes or fewer.

For configurations greater than three nodes, the mirrors must be deleted and recreated with the final endpoint at the local site and use route adds to get the mirrors created and resynced before moving the server to the final location/address/DR site.

For additional information, please refer to our CHANGEMIRRORENDPOINTS page within our documentation.

What is a DataKeeper Target snapshot?

DataKeeper’s target snapshot feature, integrated with both DataKeeper and DataKeeper Cluster Edition, is the process of creating point in time copies of replicated volumes allowing access to data on a standby cluster node without interrupting data replication from the source system. Data protection is not lost for any period of time. Enabling target snapshot allows data to be used on an otherwise idle target node without negatively impacting the performance of the source.

For more information, see our page on DataKeeper Target Snapshot.
