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.
- Number: Indicates which slot each disk occupies. Disks in the active and passive servers that occupy corresponding slots should be of the same capacity.
- Disk size: Indicates the capacity of each disk.
- Temperature: Indicates disk temperature.
- S.M.A.R.T. Status: Indicates the S.M.A.R.T. status of each disk.
- Status: Displays disk information and error notifications.
To replace malfunctioning disks:
- Check the disk number.
- Replace the malfunctioning disk with a new one. For steps regarding hard disk installation, please see the Quick Installation Guide for your Synology product.
- Go to Storage Status.
- Select the damaged volume.
- 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:
Hard disks can be added to the high-availability cluster in order to expand capacity. Before adding any hard disks, please see below.
- We recommend adding disks when both the active and passive servers are online.
- The capacity of hard disks on the passive server must be equal to or larger than disks on the active server.
To add hard disks:
- Insert the hard disks in corresponding slots of the active and passive servers. For example, if you insert one hard disk in slot 1 of the active server, then you must insert the corresponding hard disk in slot 1 of the passive server.
- Go to Main Menu > Storage Manager to fix any degraded or crashed storage spaces on the active server by clicking the Repair button.
- Return to Synology High Availability > Storage Status and to fix any degraded or crashed storage spaces on the passive server by clicking the Repair button.
