Storage

This page details the status of storage volumes and iSCSI LUNs (Block-Level) on the active and passive servers of the high-availability cluster.

Because the capacity and configurations of the corresponding volumes and iSCSI LUNs (Block-Level) on the active and passive servers must be identical, the volumes and iSCSI LUN (Block-Level) on the two servers are displayed together as single units. Therefore, if you wish to view the status of volumes and iSCSI LUNs (Block-Level) of both the active and passive servers, you must go to the Storage page (when accessing a high-availability cluster, only volumes and iSCSI LUNs (Block-Level) on the active server are viewable in Storage Manager).

Volume

This page contains the following information:

• Name: Displays the names of volumes and iSCSI LUNs (Block-Level).
• Used: Displays the space of used capacity of volumes and iSCSI LUNs (Block-Level).
• Free space: Displays the remaining available space.
• Capacity: Displays total and used capacity of volumes and iSCSI LUNs (Block-Level).
• Status: Displays the status of volumes, iSCSI LUNs (Block-Level) and SSD caches.
• Details: Displays description of errors or other information pertaining to the volume, iSCSI LUN (Block-Level) and SSD cache.

To repair a malfunctioning volume or iSCSI LUN (Block-Level):

• If a volume on one of the servers has crashed, it will be displayed on the Storage page. You can go to the HDD/SSD page to find out the drive on which the volume is built and needs to be replaced. In this case, please do the following:
  1. Replace the failed drive (for steps regarding drive installation, refer to the Hardware Installation Guide for your Synology product).
  2. Go to the Volume page and click Repair.
• If the passive server is offline, the status of volumes and iSCSI LUNs (Block-Level) will indicate an error has occurred, and none of the drives on the passive server will appear on the HDD/SSD page. In this case, you can attempt to resolve the problem by doing the following:
  1. Make sure the passive server is powered on.
  2. Check all power supplies.
  3. Examine all connections.
• If a file system error occurs on a volume or iSCSI LUN (Block-Level) on one of the servers, please do the following:
  • Go to the Volume page.
  • Click Repair.

HDD/SSD

The status of the drives is displayed in this tab.

By selecting a drive and clicking the Health Info button, you can check the details or run a S.M.A.R.T. test.
