Data asynchronous sync failed in federated gateway

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi everybody:

  I followed the instructions of Federated Configuration (http://ceph.com/docs/master/radosgw/federated-config/) to build single region and two zones environment. I have configured all settings successfully. In the final step, when the synchronization agent, ‘radosgw-agent -c region-data-sync.conf’ , is running, I saw the agent was synchronizing shards of data. After some testing by using ‘s3cmd’, I found only metadata is replicated to secondary zone which is checked by using ‘rados –p .us-east.rgw.buckets.index ls’. The data portion was missing.

 

I found the error message in the logging file of the ‘radosgw-agent’, version 1.1, that showed ‘unhashable type 'list'’. So I modified the /usr/share/pyshared/radosgw_agent/worker.py to add ‘tuple’ according to the version 1.2.2. Then the another error message ‘HttpError: Http error code 409 content {"Code":"BucketAlreadyExists"}’ occurred in the logging file.

 

Please give me some advices or suggestions. Any help would be much appreciated.

 

The packages information as follows:

OS                    Ubuntu 14.04 AMD64

Ceph               0.80.9-0ubuntu0.14.04.2

Ceph-deploy    1.4.0-0ubuntu1

Radosgw          0.80.9-0ubuntu0.14.04.2

Radosgw-agent       1.1-0ubuntu1
