how to deal with Available Resources on Management Nodes Are Going to Be Insufficient alarm on FusionCompute V1R5C00 version

The system periodically detects the usage of available resources on management nodes. This alarm is generated when the ratio of used resources to available resources hits 95%.

This alarm is cleared when the ratio is less than 95%.
Confirm the IP address of the faulty node.

On the FusionCompute portal, click Monitoring, and choose Alarm in the navigation tree on the left. On the Alarm page, locate the row that contains the alarm and click the name in the Alarm Object column.
The Service and Management Node page is displayed.

On the Service and Management Node page, view information about the management nodes and obtain the management IP address of the node whose name is the same as that of Alarm Object in Step 1.
Rectify the fault.

Use PuTTY to log in to the faulty node.
Ensure that the management IP address and username gandalf are used to establish the connection.

Run the following command and enter the password of user root to switch to user root:

su - root


Run the following command to query the inode usage of each disk:
df -i

Information similar to the following is displayed:
