ALM-73209 ZooKeeper Health Check Alarm

ALM-73209 ZooKeeper Health Check Alarm


FusionSphere OpenStack periodically (default interval: 24 hours) checks data consistency among ZooKeeper nodes. This alarm is generated when inconsistent data exists.


Alarm ID

Alarm Severity

Auto Clear







Fault Location Info

zookeeper: specifies the name of the component for which the alarm is generated.

Additional Info

  • The first parameter lists IP addresses of ZooKeeper for which the alarm is generated.
  • Second parameter:
    • XX has diff data with leader XX: specifies that ZooKeeper data is inconsistent.
    • XX has diff path with leader XX: specifies that ZooKeeper path is inconsistent.

Impact on the System

The configuration data that takes affect is inconsistent with the expected data.

Possible Causes

The network at the active site is isolated in active-active DR scenarios.


  1. Use PuTTY to log in to the first FusionSphere OpenStack node through the IP address of the External OM plane.

    The default user name is fsp. The default password is Huawei@CLOUD8.

    The system supports both password and public-private key pair for identity authentication. If the public-private key pair is used for login authentication, see detailed operations in Using PuTTY to Log In to a Node in Key Pair Authentication Mode.

    To obtain the IP address of the External OM plane, search for the required parameter on the Tool-generated IP Parameters sheet of the xxx_export_all.xlsm file exported from HUAWEI CLOUD Stack Deploy during software installation. The parameter names in different scenarios are as follows:
    • Region Type I scenario:

      Cascading system: Cascading-ExternalOM-Reverse-Proxy

      Cascaded system: Cascaded-ExternalOM-Reverse-Proxy

    • Region Type II and Region Type III scenarios: ExternalOM-Reverse-Proxy

  2. Run the following command and enter the password of user root to switch to user root:

    su - root

    The default password of user root is Huawei@CLOUD8!.

  3. Run the following command to disable user logout upon system timeout:


  4. Import environment variables and choose the CPS authentication. For details, see Importing Environment Variables.

    source set_env

    Information similar to the following is displayed:

      please choose environment variable which you want to import: 
      (1) openstack environment variable (keystone v3) 
      (2) cps environment variable 
      (3) openstack environment variable legacy (keystone v2) 
      (4) openstack environment variable of cloud_admin (keystone v3) 
      please choose:[1|2|3|4] 

  1. Run the cps zookeeper-data-check command to check the command output.

    • Information similar to the following is displayed:
      | result     | data                     |
      | consistent | diff_data:{},            |
      |            | diff_path:{},            |
      |            | leader:[u''] |

    Check whether the command output contains consistent.

    • If yes, the ZooKeeper data is consistent. You can manually clear the alarm. Alternatively, you can wait for the next alarm check period, and the alarm is automatically cleared.
    • If no, go to 6.

  2. Contact technical support for assistance.
