  • Milestone set to 5.1
  • Resolution set to fixed
  • Status changed from new to closed
  • Version set to 5.0.3

This is an incomplete multipart upload displayed. Fixed in r21127 to display these as hidden files only. You can delete the file to cancel the multipart upload.

Documentation in Unfinished multipart uploads.

  • Resolution fixed deleted

Perhaps it seems like an multipart upload, but I cannot delete it!

  • The file is displayed in the parent of where the original is
  • We cannot delete it, AWS respsonse is that the file does not exists
  • We cannot see the file in any other application or in AWS S3 Console
  • The file is not hidden - it is still displayed, even when hiding the hidden files
  • This empty file is displayed in all parenting folders back to the root of the bucket
  • We have more files in the root displayed that are not deleteable

You where right!

By using the aws command line interface I could list the files as incomplete multiparts and delete them by hand manually.

aws s3api list-multipart-uploads --bucket <yourbucket>

and to delete

aws s3api abort-multipart-upload --bucket rednun-templates-us-east-1 --key <key> --upload-id <id>

It happens a bit too often for comfort and should be another ticket why this happened in the first place, but at least we have a solution! :)
