ECS：GeoDrive - マルチパート アップロード中のエラー - ECS: 2001 - アクセス拒否 - 禁止(403)

ObjectUnderRetention
If a multi-part (MPU) PUT is used to replace an object that is in retention, it receives this error:

AccessDenied
 The issue here is that a normal PUT and a MPU PUT should return the same error but do not.

File cannot be uploaded to ECS server. Retries are exhausted (ECSxxxxx_ECSxxxxx): e:\x\x\...

2. Gather and confirm the following system and configuration information to be included the Service Request with ECS Support: 
     i. Version of GeoDrive being used
     ii. Name of the affected ECS bucket and the object user
     iii. The affected drive and any error output included in the GeoDrive console
     iv. If there were any recent changes made to the system's configuration
     v. If the affected files are larger than 128 MB (This is the default size where MPUs are used)
     vi. Has this value been changed (Option - Performance: The threshold is at the bottom of the dialog)

3. If all the affected files are 128 MB or larger, please increase the MPU threshold (If not, please notify ECS Support through a Service Request and include all prior and subsequent information)
     - This increment can be done through Options, then Performance as below (Of the two fields below, the "Minimum Threshold" is the field to be changed):


     - This should cause the larger files to avoid MPU and therefore return the correct error ("ObjectUnderRetention")
     - All files should work on retry
     - When a file is queued for upload, if it fails it will be queued for a retry. If it tries 3 times and fails each time, it gets put on a "failed upload" list. Each failed upload will log the error - After the 3rd retry, it logs an additional error:

File cannot be uploaded to ECS server. Retries are exhausted (ECSxxxxx_ECSxxxxx): e:\x\x\...

     - There is a button on the main UI screen that appears if this happens, and the user can press this button to get a list of failed uploads.
     - If the user ignores it and does not try to force a retry - After 6 hours all failed uploads are put back in the upload queue for 3 more times (All files therefore retry 3 times every 6 hours).

4. If the above does not resolve this issue, please notify ECS Support through a Service Request and include all prior information.
