Troubleshooting Failed Data Repository Tasks
When a data repository task fails, you can find the number of files that Amazon FSx
failed to
process in Files failed to export on the console's Task status
page. Or you can use the CLI or API and view the task's Status:
FailedCount property. For information about accessing this information, see Accessing Data Repository Tasks.
Amazon FSx also provides information about the specific files and directories that failed in a task completion report. The task completion report contains the file or directory path on the Lustre file system that failed, its status, and the failure reason. For more information, see Working with Task Completion Reports.

An error occurred within the Amazon FSx file system. Generally, this error code means that The Amazon FSx file system that the failed task ran on is in a FAILED lifecycle state. When this occurs, the affected files might not be recoverable due to data loss. Otherwise, you can use hierarchical storage management (HSM) commands to export the files and directories to the data repository on S3. For more information, see Exporting files using HSM commands. |
