Description

This chapter guides the administrator in handling the slow HDD.

Precautions

13. It only supports virtual storage scenarios. This function does not apply to non-virtual storage scenarios.
14. Two node scenarios do not support automatic isolation of hard disks and require manual isolation. Data Disk rebuilding is not supported after isolation. The hard disk must be replaced as soon as possible to ensure data integrity.
15. The spare disk will not automatically replace the isolated disks.
16. The slow disk will not automatically be isolated when the node and hard disk are in maintenance mode.
17. Before automatically isolating the hard disk, the virtual storage will check the integrity of the replica. If it detects that other nodes have copies in an abnormal state, isolating the current hard disk may cause the virtual machine on the hard disk to run in the None method. Manual isolation can be done according to the current situation, but this situation may cause business interruption.
18. The slow disk that appears during the upgrade process will not be automatically isolated.
19. If there is a restart node operation, the slow disk processing service will take effect after half an hour.

Prerequisites

None.

Steps

Log in to the HCI platform and view the hard disk status on the Storage >Virtual Storage > Physical Disks interface. The interface will generate an alert prompt when a slow disk failure occurs.

• When a slight slow disk alert occurred and the service is affected, you can click Isolate Disk to manually isolate the hard disk;

• When a critical slow disk alert appears, the software will automatically isolate the hard disk, and it is recommended to replace the disk as soon as possible.
