Resize a Volume Participating in Synchronous Replication
Before you begin
- Verify the upstream and downstream volumes both show online.Important: Note which volume/pool combination is the upstream volume.
- Verify there is a successful common snapshot on the upstream and downstream
volumes.Important: Note the volume collection that contains the volumes.
Procedure
- Edit the volume collection and remove the upstream volume. The downstream volume will be removed automatically. See Edit a Volume and Delete a Volume.
- Review the volumes and make note of which pool each volume contains. The upstream volume should show online. The downstream volume should show offline.
- Edit the upstream volume and resize. See Edit a Volume.
- Edit the downstream volume and resize.
- Review the volumes. Ensure they are the same size.
- Edit the volume collection and add the upstream volume back in. The downstream volume will be added automatically.
- View the volume collection. The remote recovery point should show Out of sync and the resync in progress.
- Verify the upstream and downstream volumes. Both now show the new size and the downstream is back online.
- 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.
- On the host, rescan the disk and expand the file system.
What to do next
- Verify the expansion. Perform Volume Collection Handover (from upstream pool to downstream pool).
- Verify the volumes have swapped upstream and downstream directions.
- From the host, verify the volume shows the new size.
- Perform Volume Collection Handover a second time to return to the original direction.
