Possible Causes

The quota for the alarm directory is inappropriate.

Procedure

Check whether the quota for the alarm directory is appropriate.

  1. Log in to FusionInsight Manager, and choose Cluster > Name of the desired cluster > Services > ZooKeeper. On the displayed page, choose Configurations > All Configurations > Quota. Check whether the directory for which the alarm is reported and its quota exist in the customized.quota configuration item.

    • If yes, go to 5.
    • If no, go to 2.

  2. Check whether the alarm directory for which the alarm is reported is in the following alarm list.

    • If yes, go to 3.
    • If no, go to 7.

  3. View the component of the alarm directory in the table, open the corresponding service page, and choose Configurations > All Configurations. On the displayed page, search for zk.quota in the upper right corner. The search result is the quota of the alarm directory.
  4. Check whether the quota of the alarm directory for which the alarm is reported is appropriate. The quota must be greater than or equal to the actual value, which can be obtained in Trigger Condition.
  5. Modify the services.quota value as prompted and save the configuration.
  6. After the time specified by service.quotas.auto.check.cron.expression, check whether the alarm is cleared.

    • If it is, no further action is required.
    • If no, go to 7.
