Disk Status

This page contains tabs displaying the status of disks within the high-availability cluster. Each server's respective tab shows the following information.

To replace malfunctioning disks:

  1. Check the disk number.
  2. Replace the malfunctioning disk with a new one. For steps regarding hard disk installation, please see the Quick Installation Guide for your Synology product.
  3. Go to Storage Status.
  4. Select the damaged volume.
  5. Click Repair to repair the volume.

Note:The capacity of replacement hard disks must be equal to or larger than the malfunctioning hard disk.

To add new disks to a high-availability cluster:

If you would like to add more hard disks to the high-availability cluster in order to expand capacity, please follow the instructions below.

  1. Make sure both active and passive servers are online.
  2. Insert the hard disks in corresponding slots of the active and passive servers. For example, if you insert one hard disk in slot one of the active server, then you must insert the corresponding hard disk in slot one of the passive server.
  3. When a newly added hard disk contains volumes from previous usage, errors might occur due to degraded or crashed volumes . To avoid experiencing difficulties, please follow the guidelines below:
    1. Always add new hard disks when both servers are online.
    2. After hard disks have been inserted on both the active and passive servers, go to Storage Manager to attempt to fix any data degraded or crashed volumes on the active server by clicking the Repair button.
    3. Go to the Storage Status page of Synology High Availability and attempt to fix any degraded or crashed volumes on the passive server by clicking the Repair button.
    4. If there are any degraded or crashed volumes on the newly installed hard disks, please repair them before shutting down either server.

Note: The capacity of hard disks on the passive server must be equal to or larger than disks on the active server.
