Common Faults

OBS Bucket Traffic Overload

  • Check: Use Cloud Eye to check metrics such as the number of requests, request success rate, and upload/download bandwidth.
  • Recovery:
    1. Adjust batch services at the application layer to avoid performing operations such as backups during peak hours.
    2. If this is a temporary failure, for example, network congestion, retry at the application layer. For details, see RES09 Retries After Failures.
    3. Enable overload protection for the application layer to keep high-priority services running smoothly.

OBS Object Upload/Download Failure

  • Check: The object upload or download failed.
  • Recovery:
    1. If this is a temporary failure, for example, network congestion, retry at the application layer. For details, see RES09 Retries After Failures.
    2. If the connection to an overloaded OBS bucket failed, rectify the fault by referring to "OBS Bucket Traffic Overload."

OBS Bucket Data Mistakenly Deleted

  • Check: N/A
