0%
Description
Upload a multipart object:
1. Upload part 1 with prefix 2~-DUZmxVbiv9dBycBdci2iMhiKEEUv-5
2. The connection between rgw client and server is cutoff, I don't
know if I have upload part one completely ,so I re-upload part 1 then
the part 1 is attached with a new prefix like
eOntuNHW8UdvnpbLl9UAdYGuWrL9HPH(which is tackled by rgw server )
3. The connection between rgw client and server is cutoff again, then
I re-upload part 1 with new prefix d9H1FWnoOwmr3IAejtYQJ2hyIjsUA7U
4. Upload part 2 and left parts
5. At the end, complete the upload.
The object with names below is leaked and I can not see them through
s3 client. (My upload size is 15MB and stripe size is 4M)
