Betreff: Re: radosgw - Etags suffixed with #x0e
Hi,
i was able to track down the issue further:
* Upload had been a multipart upload - Metadata are correct
* After that, the object had been copied (PUT with x-amz-copy-source) - ETag got broken
"s3cmd du" or "s3cmd ls" fails with the copied object:

I may read and write or even copy (s3cmd copy) the object again, and all is fine.
Still not clear, at what point the issue appears.
Any clues?
kind regards,
Ingo

Betreff: radosgw - Etags suffixed with #x0e
Hi,
We had a strange problem with some buckets. After a s3cmd sync, some objects got ETAGs with the suffix "#x0e". This rendered the XML output of "GET /" e.g. (s3cmd du) invalid. Unfortunately, this behaviour was not reproducable but could be fixed by "GET /{object}" + "PUT /{object}" (s3cmd get + s3cmd put).
I am not sure, how this appeared and how to avoid that. Just now, we have nautilus mons and osds with jewel radosgws. At the time of first appearence, also a nautilus gateway had been online, but the requests had been handled by both types.
Any ideas?
best regards,
Ingo
