how to deal with Standby Node Database Is Abnormal alarm on FusionCompute V1R5C00 version

This alarm is generated when the system detects that the database on the standby Virtualization Resource Management (VRM) node does not work properly.

This alarm is cleared when the standby VRM node database works properly.
On the FusionCompute portal, click System, and choose System Configuration > Service and Mgmt. Node in the navigation tree on the left.

On the displayed Service and Mgmt. Node page, obtain the standby VRM node name in the table of the Service list area, and view the IP address of the standby VRM node in the table of the Management node area.


Use PuTTY to log in to the standby VRM 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 stop the High Availability (HA) process on the standby node:
service had stop

Run the following command to stop the database process:
su - postgres -c "gs_ctl stop"

Run the following command to start the database process:
su - postgres -c "gs_ctl start -M standby"

Check whether the database is started:

If yes, go to Step 8.
If no, go to Step 12.

Run the following command to rebuild the database:
su - postgres -c "gs_ctl build -b incremental -M standby"

Check whether the database is rebuilt:

If yes, go to Step 10.
If no, go to Step 12.

Run the following command to start the HA process:
service had start

After about 5 minutes, log in to the FusionCompute portal and check whether the alarm is cleared.
