Impact on the System


Possible Causes

  • An exception occurs when a request for deleting all snapshots is delivered to the FusionSphere OpenStack Cinder.
  • A network exception occurs or error information is returned when the system delivers the snapshot query information.
  • The snapshot status is not available or error and so cannot be deleted.
  • The FusionSphere OpenStack Cinder deleting the snapshot times out.
  • An exception occurred when sending a snapshot deletion request to the FusionSphere OpenStack Cinder.
  • The bottom-layer deletion fails. As a result, the status of the snapshot to be deleted changes to error_deleting.


  1. Log in to ManageOne Maintenance Portal using a browser.

    • The login address is https://Address for accessing ManageOne Maintenance Portal:31943, for example,
    • Default username: admin; default password: Huawei12#$

  2. In the navigation tree, choose Alarms > Event Logs. Click Filter to filter the event based on the event name.
  3. Query the following event information:

    • Fault Location Info (including VolumeID, TenantID, and JobID)
    • Additional Info
    • Generated At

  4. Query Additional Info. If Operation is deleteSnapshot, it indicates that the snapshot fails to be deleted. If Failed to Delete a Snapshot is displayed,

    check whether the error information contains the following information:

    If delete snapshot: Bad or unexpected response from the storage volume backend API is displayed, the cinder-volume fails to delete the snapshot. Check whether the error information contains the following information:

    If REST unauthorized is contained, the device responds an authorization exception when the cinder driver connects to the device. Check whether the Management Storage Link or Authentication Failure alarm (alarm ID: 6024) is reported on ManageOne Maintenance Portal. If the alarm exists, clear the alarm by referring to HUAWEI CLOUD Stack 6.5.0 Alarm&Event Reference.

    If the preceding information is not displayed or the failure cause cannot be identified, go to 6.

  5. If a joint locating with other components is required and the alarm information does not provide information for locating faults occurred on other components, obtain the location information from the log. If no, skip this step.

    1. Use PuTTY to log in to the CPT-SRV01 node using the IP address corresponding to the CPT-SRV01 field (searching in the xxx_export_all_EN.xlsm file) and log in to the CPT-SRV02 node using the IP address corresponding to the CPT-SRV02 field (searching in the xxx_export_all_EN.xlsm file).

      Default account: apicom, default password: Huawei12#$

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

      The default password of user root is Cloud12#$.

      sudo su root

    3. Run the following command to switch to the directory containing EVS disk logs:

      cd /var/log/apicom/taskmgr/dbs

    4. Run the following command to query all logs relating to the task based on JobID:

      grep -n "jobId" * | less

    5. If the obtained log information is too much for viewing, use query composition to query precise information.
      • An example is provided to query the metadata update:

        grep -n "jobId" * | grep "update volume\[disk ID\] metadata, new metadata is" | less

      • An example is provided to query the log information of one specific minute:

        grep -n "jobId" * | grep "2018-04-10 12:07" | less

  6. Query Additional Info and perform the following steps to find the failure cause:

    1. Query Additional Info and determine the cause accordingly.
      • If Additional Info contains snapshot status must be available or error when delete snapshot, it indicates that the snapshot is not in available or error state and cannot be deleted.
      • If Additional Info contains snapshot is error_deleting, it indicates that the snapshot fails to be deleted and the snapshot status changes to error_deleting.
      • If Additional Info contains ClientException or ConnectException, it indicates that the network is abnormal or an error message is returned when the snapshot is deleted.
    2. Locate the fault by referring to Troubleshooting Guide for Typical Cinder Problems and provide the snapshot ID and last occurrence time to the FusionSphere OpenStack Cinder O&M personnel to locate and rectify the fault.

  7. After the fault is rectified, ask the user to delete the snapshot again.
