Re: RGW unable to start gateway for 2nd realm

This is the documentation that has always worked for me to set up multiple realms.  http://docs.ceph.com/docs/luminous/radosgw/multisite/  It's for the multisite configuration, but if you aren't using multi-site, just stop after setting up the first site.  I didn't read through all of your steps, but I've never had a problem following these steps.  Make sure to replace 'luminous' with your ceph version if it isn't luminous.  One thing I noticed in Luminous is that you only need like 5 metadata pools for RGW now due to namespaces in the pools.

Hi All,
  I'm having issues trying to get a 2nd Rados GW realm/zone up and running.  The configuration seemed to go well, but I'm unable to start the gateway.

Existing RadosGW .. this one works fine
Realm : realm01 (default)
zonegroup: us (master, default)
zone: us-prd-1 (master, default)

The problem comes when I'm attempting to add a new realm.
New Realm: realmtest
new ZG: maintest (master)
new zone: lumtest (master)

Steps taken:
=========
* Created new rgw pools lumtest.rgw.* (14 pools) on dedicated root
*  radosgw-admin realm create --rgw-realm=realmtest 
*  radosgw-admin zonegroup create --rgw-zonegroup=maintest --rgw-realm=realmtest --master
* radosgw-admin zone create --rgw-realm=realmtest --rgw-zonegroup=maintest --rgw-zone=lumtest --master
* radosgw-admin user create --rgw-realm realmtest --rgw-zonegroup maintest --rgw-zone lumtest --uid="REMOVED" --display-name="System User" --system
* radosgw-admin zone modify -rgw-realm realmtest --rgw-zonegroup maintest --rgw-zone lumtest  [added the access key and secret of system user]
*  radosgw-admin user create --rgw-realm realmtest --rgw-zonegroup maintest --rgw-zone lumtest --uid="test" --display-name="test User"
* radosgw-admin period update --rgw-realm realmtest

ceph.conf
========
[client.radosgw.rgw-test]
host = rgw-test
keyring = /etc/ceph/ceph.client.radosgw.rgw-test
log file = /var/log/ceph/radosgw.rgw-test
rgw frontends = civetweb port=80
rgw realm=realmtest
rgw zonegroup=maintest
rgw zone=lumtest
