how to deal with Failed to Back up or Upload Key Data on the VRM Node alarm on FusionCompute V1R5C00 version

This alarm is generated when the system detects that key data fails to be backed up or uploaded from the Virtualization Resource Management (VRM) node to the File Transfer Protocol (FTP) server.

The number of key data copies saved on the FTP server exceeds 7 and the deletion of the earliest key data copies fails.
On FusionCompute, choose Monitoring > Alarm. On the Alarm page, click the alarm object name.
The Service and Management Node page is displayed.

On the Service and Management Node page, view the management node information and obtain the management IP address of the alarm object viewed in Step 1.
Use PuTTY to log in to the node for which the alarm is generated.
Ensure that the management IP address and username gandalf are used to establish the connection.

Run the df -h command to check whether the value in the Avail column of the /var/backup directory is greater than the sum of the values in the Used columns of the /opt/gaussdb directory and the /etc/galax directory.
