The changes involved in introducing the deep-flatten feature in the Infernalis release resulted in new clone copy-on-write handling. I would suggest retrying with a jewel release client. On Tue, Apr 11, 2017 at 6:56 AM, 许雪寒 wrote: > Thanks for your help:-) > > By the way, could you give us some h

Re: [ceph-users] How to cut a large file into small objects

Re: [ceph-users] Kraken release and RGW --> "S3 bucket lifecycle API has been added. Note that currently it only supports object expiration."

After much banging on this and reading through the Ceph RGW source, i figured out Ceph RadosGW returns -13 ( EACCES - AcessDenied) if you dont pass in a 'Prefix' in your S3 lifecycle configuration setting. It also returns EACCES if the XML is invalid in any way, which is probably not the most corre
