Users Cannot Access Object Storage Using OBS Console Because There Is a Time Difference Between the Browser and the Storage Server

Context

If the difference between the time displayed on the PC where the browser for visiting OBS Console resides (client time) and that on the corresponding FusionStorage OBS server (server time) is shorter than 15 minutes, you can access object storage using OBS Console. If the time difference is longer than 15 minutes, you cannot access object storage using OBS Console and an error will be reported.

Symptom

The time difference is longer than 15 minutes between the client and the server. Ensure that the time on the client is configured correctly. is displayed on OBS Console.

Possible Causes

The difference between the client time and the server time is greater than 15 minutes.

Procedure
  1. Open a browser and log in to the OceanStor DeviceManager.

    Login address: https://IP address:8088.

    The default user name and password are admin and Admin@storage.

    NOTE:
    • If HUAWEI CLOUD Stack Deploy is used to install OBS, the default password is forcibly changed to Huawei@123.
    • IP address indicates of the storage device. In HUAWEI CLOUD Stack Deploy, export the Excel of the engineering parameter summary for deploying FusionStorage OBS in the first region and search for the value of obs_poe_business_float_ip in the Excel.
    • If a firewall is deployed, port 8088 must be enabled when the system provides web services.
    • The browser may display a message indicating that the security certificate of the website is incorrect. If the IP address is correct, you can ignore the message and continue to access the storage device

      Login address: https://DMK floating IP address:8443.

      The default user name and password are obs and Huawei@123.

      NOTE:

      DMK floating IP address: In HUAWEI CLOUD Stack Deploy, export the Excel of the engineering parameter summary for deploying the first region and search for the value of DMK-Float-IP in the Excel.

    2. In the navigation pane on the left, click Deploy Guide. On the Service Configuration page, choose Services > DNS-Internal. Set Select Version to 1.1.8 and Select Action to Domain Config, and retain the default values for other parameters. See Figure 13-1.
