Object Gateway not working within the dashboard anymore after network change
Hi all, we are currently experiencing a problem with the Obejct Gateway part of the dashboard not working anymore: We had a working setup were the RGW servers only had 1 network interface with an IP address that was reachable by the monitor servers and the dashboard was working as expected. After our initial tests everything was working great and we decided to add another physical link to the RGW Servers for the traffic to the clients. With that network change we also had to set the default gateway to the new interface while adding static routes for the rest of the ceph environment. To avoid issues with hostnames (the old hostname now resolves to the new interface) we added another hostname for the internal traffic, purged the gateways from ceph and added them again via ceph-deploy rgw create with the new hostname. The S3 communication is working perfectly fine as it did before, we can reach all buckets and the monitors can communicate with the Gateway. The Dashboard however throws the following error whenever we navigate to any of the object gateway menus: ————————————————————————————————— 2020-07-03 10:33:41.871 7fa0f9dbc700 0 mgr[dashboard] [03/Jul/2020:10:33:41] HTTP Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/cherrypy/_cprequest.py", line 656, in respond response.body = self.handler() File "/usr/lib/python2.7/site-packages/cherrypy/lib/encoding.py", line 188, in __call__ self.body = self.oldhandler(*args, **kwargs) File "/usr/lib/python2.7/site-packages/cherrypy/_cptools.py", line 221, in wrap return self.newhandler(innerfunc, *args, **kwargs) File "/usr/share/ceph/mgr/dashboard/services/exception.py", line 88, in dashboard_exception_handler return handler(*args, **kwargs) File "/usr/lib/python2.7/site-packages/cherrypy/_cpdispatch.py", line 34, in __call__ return self.callable(*self.args, **self.kwargs) File "/usr/share/ceph/mgr/dashboard/controllers/__init__.py", line 661, in inner ret = func(*args, **kwargs) File "/usr/share/ceph/mgr/dashboard/controllers/rgw.py", line 28, in status if not instance.is_service_online(): File "/usr/share/ceph/mgr/dashboard/rest_client.py", line 507, in func_wrapper **kwargs) File "/usr/share/ceph/mgr/dashboard/services/rgw_client.py", line 321, in is_service_online _ = request({'format': 'json'}) File "/usr/share/ceph/mgr/dashboard/rest_client.py", line 313, in __call__ data, raw_content) File "/usr/share/ceph/mgr/dashboard/rest_client.py", line 445, in do_request ex.args[0].reason.args[0]) File "/usr/lib64/python2.7/re.py", line 137, in match return _compile(pattern, flags).match(string) TypeError: expected string or buffer 2020-07-03 10:33:41.872 7fa0f9dbc700 0 mgr[dashboard] [2a02:2e0:13::a05:42784] [GET] [500] [45.044s] [plusline] [1.8K] /api/rgw/status 2020-07-03 10:33:41.872 7fa0f9dbc700 0 mgr[dashboard] ['{"status": "500 Internal Server Error", "version": "3.2.2", "traceback": "Traceback (most recent call last):\\n File \\"/usr/lib/python2.7/site- packages/cherrypy/_cprequest.py\\", line 656, in respond\\n response.body = self.handler()\\n File \\"/usr/lib/python2.7/site-packages/cherrypy/lib/encoding.py\\", line 188, in __call__\\n self.b ody = self.oldhandler(*args, **kwargs)\\n File \\"/usr/lib/python2.7/site-packages/cherrypy/_cptools.py\\", line 221, in wrap\\n return self.newhandler(innerfunc, *args, **kwargs)\\n File \\"/usr/s hare/ceph/mgr/dashboard/services/exception.py\\", line 88, in dashboard_exception_handler\\n return handler(*args, **kwargs)\\n File \\"/usr/lib/python2.7/site-packages/cherrypy/_cpdispatch.py\\", l ine 34, in __call__\\n return self.callable(*self.args, **self.kwargs)\\n File \\"/usr/share/ceph/mgr/dashboard/controllers/__init__.py\\", line 661, in inner\\n ret = func(*args, **kwargs)\\n F ile \\"/usr/share/ceph/mgr/dashboard/controllers/rgw.py\\", line 28, in status\\n if not instance.is_service_online():\\n File \\"/usr/share/ceph/mgr/dashboard/rest_client.py\\", line 507, in func_w rapper\\n **kwargs)\\n File \\"/usr/share/ceph/mgr/dashboard/services/rgw_client.py\\", line 321, in is_service_online\\n _ = request({\'format\': \'json\'})\\n File \\"/usr/share/ceph/mgr/dashb oard/rest_client.py\\", line 313, in __call__\\n data, raw_content)\\n File \\"/usr/share/ceph/mgr/dashboard/rest_client.py\\", line 445, in do_request\\n ex.args[0].reason.args[0])\\n File \\"/usr/lib64/python2.7/re.py\\", line 137, in match\\n return _compile(pattern, flags).match(string)\\nTypeError: expected string or buffer\\n", "detail": "The server encountered an unexpected condition which prevented it from fulfilling the request.", "request_id": "e0d6ff11-4dad-496a-9ee7-9db036c46ab7"}'] ————————————————————————————————— We are running ceph version 14.2.9 on CentOS 7.7.

Hello Dominic, thank you for you quick help, I did change the settings but maybe to the wrong host: The endpoint for the clients would be something like $bucketname.s3.url.com, i therefor set the api-host to s3.url.com (which worked before). Now that I am writing this I realize that the dashboard hosts do not have access to that URL. As i have 2 RGW Server it would probably be a bad idea to just point it to one of them? Thanks, Hendrik

Hendik; I'm assuming that s3.url.com round robin DNSed to the new interface on each host. I don't see a problem with pointing the dashboard at one of the hosts directly. Though there is no load balancing in that kind of setup. I don't believe the dashboard represents a significant load. If the load balancing is a concern to you, you could setup another round robined DNS, at (for instance): rgw.url.com, and direct the dashboard there. You could also use an IP address instead of a URL. You mentioned setting static routes between the RGW hosts and the Ceph cluster; you might consider moving the Ceph (old) interfaces into the Ceph Public network subnet. This would reduce the complexity of your overall setup, and possibly improve maintainability. Just a thought. Thank you, Dominic L.
