Ceph » rgw

Hello,

We have a problem regarding our Ceph upgrade. When we upgrade from Giant to Hammer, all objects beginning with the symbole '_' are no more found when we run Hammer version.

Here are the details:
- Running giant version, we created 2 objects : ['_test'] and ['test']
- We upgrade to hammer version
- service ceph restart on all the cluster nodes : The object are STILL readable.
- service ceph-radosgw restart on the RADOS Gateway, the object is no more readable with the following error :
/usr/local/share/gems/gems/aws-sdk-v1-1.64.0/lib/aws/core/client.rb:375:in `return_or_raise': No Such Key (AWS::S3::Errors::NoSuchKey)
from /usr/local/share/gems/gems/aws-sdk-v1-1.64.0/lib/aws/core/client.rb:476:in `client_request'
from (eval):3:in `get_object'
from /usr/local/share/gems/gems/aws-sdk-v1-1.64.0/lib/aws/s3/s3_object.rb:1371:in `get_object'

from ./read.ry:12:in `<main>'

In the radosgw.log, we can find :
2015-05-28 11:47:05.365099 7f061a7a3700 1 ====== req done req=0x7f06600336b0 http_status=404 ======

Is that a well known bug ?

Kind regards,
