Resize a Volume Participating in Synchronous Replication

  1. Verify the upstream and downstream volumes both show online.
    IMPORTANT: Note which volume/pool combination is the upstream volume.
  2. Verify there is a successful common snapshot on the upstream and downstream volumes.
    IMPORTANT: Note the volume collection that contains the volumes.
  1. Edit the volume collection and remove the upstream volume. The downstream volume will be removed automatically. See Edit a Volume and Delete a Volume.
  2. Review the volumes and make note of which pool each volume contains. The upstream volume should show online. The downstream volume should show offline.
  3. Edit the upstream volume and resize. See Edit a Volume.
  4. Edit the downstream volume and resize.
  5. Review the volumes. Ensure they are the same size.
  6. Edit the volume collection and add the upstream volume back in. The downstream volume will be added automatically.
  7. View the volume collection. The remote recovery point should show Out of sync and the resync in progress.
  8. Verify the upstream and downstream volumes. Both now show the new size and the downstream is back online.
  9. Verify there is a fresh common snapshot on the upstream and downstream volumes. This ensures the new snapshot can be able to replicate downstream, for recovery.
  10. On the host, rescan the disk and expand the file system.
After the volume collection is resynchronized, verify that the volume collection works as expected.
  1. Verify the expansion. Perform Volume Collection Handover (from upstream pool to downstream pool).
  2. Verify the volumes have swapped upstream and downstream directions.
  3. From the host, verify the volume shows the new size.
  4. Perform Volume Collection Handover a second time to return to the original direction.
