Description James Biao 2016-04-19 00:58:33 UTC 
Description of problem:

The following warning / notice should be included in Ceph documentation, erasure coding pool part.

"The RGW needs at least 1 pool to be on a replicated pool vs EC.  Specifically, the .rgw.buckets.extra pool must be a replicated pool."

This is from SME Michael Kidd in support case 01618963.

Customer configured all pools in erasure coding pool. When creating new bucket, it hits

WARNING: set_req_state_err err_no=95 resorting to 500
req 388:0.015874:s3:PUT /MYTEST/:create_bucket:http status=500

err_no=95 suggests "Operation not supported on transport endpoint"

Customer modified all of the radosgw pools EXCEPT .rgw.buckets (left it erasure coded) and made them replicated and it works.
