Processing error alarm


Parameter Name

Parameter Description


Indicates the alarm name.


Indicates the abnormal service address and instance.


Indicates the returned error message.


Indicates the possible cause.

Impact on the System

If inter-instance files fail to be synchronized, the required file may not be found.

System Actions


Possible Causes

  • The required file fails to be downloaded due to the network fault.
  • Data sending fails due to the network fault.
  • The Kubernetes service fails to obtain the SWR instance.


  1. Use PuTTY to log in to the manage_lb1_ip node.

    The default username is paas, and the default password is QAZ2wsx@123!.

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

    su - root

    Default password: QAZ2wsx@123!

  3. Check whether SWR instances are working properly.

    Run the kubectl get pod -owide -n fst-manage |grep swr-api-server command to obtain all SWR instances. SWR is deployed in high availability (HA) mode. Ensure that the number of SWR instances is greater than or equal to two. Check whether the instance status is Running.

    swr-api-server-4042020123-g3cx4            1/1       Running   0          9d       manage-cluster5-3063fc5a-t4c0v
    swr-api-server-4042020123-nk8x3            1/1       Running   0          9d       manage-cluster4-3063fc5a-n41xn
    swr-api-server-4042020123-z53ws            1/1       Running   0          9d      manage-cluster4-3063fc5a-bzdfd
    • If yes, go to 4.
    • If no, go to 5.

  4. Check whether the network connection between SWR instances is normal.

    1. Run the kubectl exec -it swr-api-server-4042020123-g3cx4 bash -n fst-manage command to go to the SWR instance container. swr-api-server-4042020123-g3cx4 indicates the instance name, which can be obtained from the displayed informationin 3.
    2. Run the ping and ping commands to check whether the network connection between the swr-api-server-4042020123-g3cx4 instance and other SWR instances is normal. The IP addresses such as and can be obtained from 3.
     [paas@swr-api-server-4042020123-g3cx4 dockyard]$  ping
    PING ( 56(84) bytes of data.
    64 bytes from icmp_seq=1 ttl=64 time=0.950 ms
    64 bytes from icmp_seq=2 ttl=64 time=0.223 ms
    64 bytes from icmp_seq=3 ttl=64 time=0.224 ms

    3 packets transmitted, 3 received, 0% packet loss, time 2001ms
    rtt min/avg/max/mdev = 0.223/0.465/0.950/0.343 ms
    • If the network connection is normal, go to 7.
    • If the network connection is abnormal, go to 6.

  5. Follow the instructions in section ALM-13 Pod Is Abnormal to handle the SWR instance exception if any.
  6. Contact the network administrator to rectify the network fault if any.
  7. Contact technical support for other issues.

Alarm Clearing

This alarm is automatically cleared when inter-instance files are normally synchronized.
