Hi:
   Everyone!
  I am trying to setup replication on two clusters right now.
  please  go through my previous steps.
  on the slave zone(cluster),     when i do the follow command, I  found som errors:

no，i set up replication between two clusters,each cluster has  one zone, both clusters are in the same region. but  i got some errors.

Are you trying to setup replication on one cluster right now?

Generally replication is setup between two different clusters, each having one zone.  Both clusters are in the same region.  

I can't think of a reason why two zones in one cluster wouldn't work.  It's more complicated to setup though.  Anything outside of a test setup would need a lot of planning to make sure the two zones are as fault isolated as possible. I'm pretty sure you need separate RadosGW nodes for each zone.  It could be possible to share, but it will be easier if you don't.


I still haven't gone through your previous logs carefully.

}
5.Create Zone Users system user
sudo radosgw-admin user create --uid="us-east" --display-name="Region-US Zone-East" --name client.radosgw.us-west-1 --access_key="XNK0ST8WXTMWZGN29NF9" --secret="7VJm8uAp71xKQZkjoPZmHu4sACA1SY8jTjay9dP5" --system
sudo radosgw-admin user create --uid="us-west" --display-name="Region-US Zone-West" --name client.radosgw.us-west-1 --access_key="AAK0ST8WXTMWZGN29NF9" --secret="AAJm8uAp71xKQZkjoPZmHu4sACA1SY8jTjay9dP5" --system
6.reboot
sudo /etc/init.d/ceph -a restart
sudo /etc/init.d/httpd restart
sudo /etc/init.d/ceph-radosgw restart
after all of above, on the first cluster, i do the follow steps
1.source self.env
the content of self.env is :
cat self.env
export ST_AUTH="http://10.18.5.49/auth/1.0"
export ST_KEY=ffJm8uAp71xKQZkjoPZmHu4sACA1SY8jTjay9dP5
export ST_USER=us-test-east:swift
2.swift list
3.swift  upload test  self.env
4.swift list test
self.env
5.sudo radosgw-agent -c ./ceph-data-sync.conf
the content of ceph-data-sync.conf is：
cat ceph-data-sync.conf
src_access_key: XNK0ST8WXTMWZGN29NF9
src_secret_key: 7VJm8uAp71xKQZkjoPZmHu4sACA1SY8jTjay9dP5

dest_access_key: XNK0ST8WXTMWZGN29NF9
dest_secret_key: 7VJm8uAp71xKQZkjoPZmHu4sACA1SY8jTjay9dP5
log_file: /var/log/radosgw/radosgw-sync-us-east-west.log
there is some error as bellow：
sudo radosgw-agent -c ./ceph-data-sync.conf

on the second cluster ，i do the follow steps：
1.source self.env
the content of self.env is :
cat self.env
export ST_AUTH="http://10.18.5.51/auth/1.0"
export ST_KEY=ffJm8uAp71xKQZkjoPZmHu4sACA1SY8jTjay9dP5
export ST_USER=us-test-east:swift
2.swift list

3.radosgw-admin --name client.radosgw.us-west-1 user info --uid="us-test-east"

  "user_quota": { "enabled": false,
      "max_size_kb": -1,
      "max_objects": -1},
  "temp_url_keys": []}
4.radosgw-admin --name client.radosgw.us-west-1 bucket list
[
    "test"]
5.radosgw-admin --name client.radosgw.us-west-1 --bucket=test  bucket list
[]

it seems like that metadata is replicated from the first cluster， data is not。
I don't known why?
