Storage Status
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 Status page [when accessing a high-availability cluster, only volumes and iSCSI LUNs (Block-Level) on the active server are viewable in Storage Manager].
This page contains the following information:
- Name: Displays the names of volumes and iSCSI LUNs (Block-Level).
- Used: Displays the percentage of used capacity of volumes and iSCSI LUNs (Block-Level).
- Used/Total Size: Displays total and used capacity of volumes and iSCSI LUNs (Block-Level).
- Status: Displays the status of volumes and iSCSI LUNs (Block-Level).
- Description: Displays description of errors or other information pertaining to the volume and iSCSI LUN (Block-Level).
To repair a malfunctioning volume or iSCSI LUN (Block-Level):
- If a hard disk on one of the servers has crashed, you can go to the Disk Status page to determine which hard disk has crashed and needs to be replaced. In this case, please do the following:
- Replace the crashed hard disk (for steps regarding hard disk installation, please refer to the Quick Installation Guide for your Synology product).
- Go to the Storage Status 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 disks on the passive server will appear on the Disk Status page. In this case, you can attempt to resolve the problem by doing the following:
- Make sure the passive server is powered on.
- Check all power supplies.
- 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 Storage Status page.
- Click Repair.
Note: The limit of volumes and iSCSI LUNs (Block-Level) on a high-availability cluster is 64.
