Fault Domain (Cluster Mode)

Click the Fault Domain in the navigation bar to enter Fault Domain page.

view the status of each fault domain. Determine the fault domain level at system initialization.

Fault Domain Level: Disk Path

If the fault domain is set at the disk path level during initialization, you can view the specific details of each path.

Name	Description
Disk path	Specific disk path.
Disk path utilization	Disk usage rate where thedisk pathis located.
Disk path capacity	Capacity of the disk where the disk path is located.
Disk pathused capacity	Used capacity of the disk where the disk path is located.
Health status	Health status: l Healthy: The disk path is in a healthy state and can be read and written normally, and the disk usage of the disk path does not exceed 90%. l Warning: The disk path is warning and is readable, but one or more of the following situations exist: slow disk, the utilization rate of the disk where the diskpathis located exceeds 90%,the remaining disk space is less than 1GiB,or HBlock stops writing to this path. l Error: The disk path is in an error state and cannot be accessed. The reasons may be that an I/O error occurs on the disk, resulting in the inability to read or write, or the disk path is not mounted correctly, etc.
HealthDetail	Health details: l If the health status isHeathy, this column is empty. l If the health status isWarningorError, detailed information about the warning or error is displayed.

Fault Domain Level: Server

If the fault domain level is set to the server during initialization, you can view the data service health status of each fault domain.

Name	Description
Server	Specific server ID. The health status of the fault domain can be judged based on the color: blue for healthy, yellow for warning, and red for error. By hovering over a specific server, you can view theDisk path utilization,Disk path capacity,Disk pathused capacity, andHealth status.
Disk path utilization	Averagediskpath usage of the server, thatis,the averagevalueof alldiskpaths' usage rates.
Disk path capacity	Total capacity of all disks where the disk paths are located on the server.
Disk pathused capacity	Used capacity of all disks wherediskpaths are located on the server.
Health status	Health status of the data services: l Heathy: The status of the fault domain is healthy, and all data services in the fault domain are in the Healthy status. l Warning: The status of the fault domain is Warning, and some of the data services in the fault domain is Warning or Error status. l Error: The fault domain status is Error and all data services in the fault domain are in Error status.
Diskpath	Specific disk path and disk path usage. Click on a specific disk path,you canview the detailed information of the disk path, includingDisk path,Disk path utilization,Disk path capacity,Disk pathused capacity,Health status,HealthDetail.
Disk path	Specific disk path.
Disk path utilization	Disk usage rate where thedisk pathis located.
Disk path capacity	Capacity of the disk where the disk path is located.
Disk pathused capacity	Used capacity of the disk where the disk path is located.
Health status	Health status: l Healthy: The disk path is in a healthy state and can be read and written normally, and the disk usage of the disk path does not exceed 90%. l Warning: The disk path is warning and is readable, but one or more of the following situations exist: slow disk, the utilization rate of the disk where the diskpathis located exceeds 90%,the remaining disk space is less than 1GiB,or HBlock stops writing to this path. l Error: The disk path is in an error state and cannot be accessed. The reasons may be that an I/O error occurs on the disk, resulting in the inability to read or write, or the disk path is not mounted correctly, etc.
HealthDetail	Health details: l If the health status isHeathy, this column is empty. l If the health status isWarningorError, detailed information about the warning or error is displayed.
