ALM-12072 FloatIP Resource Is Abnormal

Alarm Description

HA checks the floatip resources of Manager every 9 seconds. This alarm is generated when HA detects that the floatip resources are abnormal for 3 consecutive times.

This alarm is cleared when the FloatIP resource is normal.

Resource Type of FloatIP is Single-active. Active/standby will be triggered upon resource exceptions. When this alarm is generated, the active/standby switchover is complete and new FloatIP resources have been enabled on the new active FusionInsight Manager. In this case, this alarm is cleared. This alarm is used to notify users of the cause of the active/standby switchover.

Impact on the System

The alarm persists for a long time, causing frequent active/standby switchovers of FusionInsight Manager. As a result, users cannot log in to FusionInsight Manager and perform O&M operations.

The FloatIP process is repeatedly restarts, which may lead to the failure to visit the native service UI.

Possible Causes

The floating IP address is abnormal.

Handling Procedure

Check the floating IP address status of the active management node.

In the alarm list on FusionInsight Manager, locate the row that contains the alarm, and view the address of the host for which the alarm is generated and the resource name.
Log in to the active management node as user root.
Run the following command, go to the ${BIGDATA_HOME}/om-server/om/sbin/ directory.

su - omm

cd ${BIGDATA_HOME}/om-server/om/sbin/
Run the sh status-oms.sh command, and execute the status-oms.sh script to check whether the floating IP address of the active FusionInsight Manager is normal. View the command output, locate the row where ResName is floatip, and check whether the following information is displayed.

For example:
```
10-10-10-160 floatip Normal Normal Single_active
```
- If it is, go to 8.
- If it is not, go to 5.
Run the ifconfig command to check whether the NIC with the floating IP address exists.
- If it does, go to 8.
- If it does not, go to 6.
Run the ifconfig NIC name Floating IPaddress netmask Subnet mask command to reconfigure the NIC with the floating IP address. (For example, ifconfig eth0 10.10.10.102 netmask 255.255.255.0).
Five minutes later, check whether the alarm is cleared.
- If it is, no further action is required.
- If it is not, go to 8.
