Failure in Creating Containerized Applications After CPU Cores Are Recovered

Failure in Creating Containerized Applications After CPU Cores Are Recovered

Symptom

Containerized applications fail to be created after CPU cores are recovered.

Possible Causes

CPU cores are abnormal.

Troubleshooting Method

  1. Log in to FusionStage.

    1. Use a browser to log in to ManageOne Operation Portal (ManageOne Tenant Portal in B2B scenarios) as a VDC administrator or VDC operator.
      Login address:
      • Login address in a non-B2B scenario: https://Address for accessing ManageOne Operation Portal, for example, https://console.demo.com.
      • Login address in the B2B scenario: https://Address for accessing ManageOne Tenant Portal, for example, https://tenant.demo.com
    2. Select your region and then project from the drop-down list on the top menu bar.
    3. Choose Console > Application > FusionStage from the main menu.

  2. Choose Application Publishing > Application Management from the main menu.
  3. Select the containerized application that fails to be created.

    The application details page is displayed.

  4. On the Instances tab page, check the status of the containerized application.

    If the value of the Status column contains Requested CPUs are not available - requested 0-3, available: 0,2-3, as shown in Figure 20-1, CPU cores are abnormal.

  5. Use PuTTY to log in to the node where the application resides as the paas user.
  6. Run the following command and enter the password of the root user to switch to the root user:

    su - root

    Default password: QAZ2wsx@123!

  7. Run the following command to check the CPU core status:

    lscpu

    If the value of Off-line CPU(s) list is not 0, CPU cores are abnormal, as shown in Figure 20-2.

    Figure 20-2 Checking the CPU core status

    The results in 4 and 7 indicate that the containerized application fails to be created after the CPU cores are recovered.

  8. Migrate the application that fails to be created to another node. If the fault persists, contact technical support for assistance.
