Alarm Description

The system executes the periodic backup task every 60 minutes. This alarm is generated when a periodical backup task fails to be executed. This alarm is cleared when the next backup task is executed successfully.

Alarm Attributes

Alarm Parameters

Impact on the System

The periodic backup task failed, resulting in no available backup packages during the time period when the backup failed. When a system exception occurs and you need to use the backup package to restore data, no backup package is available during the failure period. As a result, data during the failure period cannot be restored.

Possible Causes

The alarm cause depends on the task details. Handle the alarm according to the logs and alarm details.

Handling Procedure

Check whether the disk space is sufficient.

1. In the FusionInsight Manager portal, click O&M > Alarm > Alarms.
2. In the alarm list, click in the row where the alarm is located and obtain TaskName from Location.
3. Log in to the active node of the cluster as the root user and check whether information similar to the following is recorded in backup and restoration logs in /var/log/Bigdata/controller/backup/.

   Upload backup files to *** file failed, error info: ***

   • If yes, go to 4.
   • If no, go to 7.

4. On FusionInsight Manager, choose O&M > Backup and Restoration > Backup Management. Locate the backup task based on TaskName, click Configure in the Operation column, and check whether all configuration items are correctly configured.
   • If yes, go to 7.
   • If no, modify the configuration, save the modification, and go to 5.

5. Choose More > Back Up Now to start the backup task and check whether the backup task is successfully executed.
   • If yes, go to 6.
   • If no, go to 7.

6. After 2 minutes, check whether the alarm is cleared.
   • If yes, no further action is required.
   • If no, go to 7.

7. Choose More > View History in the Operation column. In the displayed dialog box view the task details.
8. In the displayed dialog box and click to check whether the following message is displayed: Failed to backup xx due to insufficient disk space, move the data in the xx directory to other directories.
   • If yes, go to 9.
   • If no, go to 16.

9. Choose Backup Path > View and obtain the Backup Path.
10. Log in to the node as user root and run the following command to check the node mounting details:

    df -h

11. Check whether the available space of the node to which the backup path is mounted is less than 20 GB.
    • If yes, go to 9.
    • If no, go to 16.

12. Check whether there are many backup packages in the backup directory.
    • If yes, go to 13.
    • If no, go to 16.

13. Enable the available space of the node to which the backup directory is mounted to be greater than 20 GB by moving backup packages out of the backup directory or delete the backup packages.
14. After the problem is resolved, perform the backup task again and check whether the backup task execution is successful.
    • If yes, go to 15.
    • If no, go to 16.

15. After 2 minutes, check whether the alarm is cleared.
