Ceph RDMA setting for public/cluster network

by Liu, Changcheng

Hi all, Does anyone know how to set "ms_async_rdma_device_name" for OSD in ceph.conf in production environment? When deploying Ceph, it’s better to isolate public & cluster network. For OSD daemon, public & cluster network use different configuration means that they need use different rdma device. Then, how could we set different rdma device name under same [OSD.x] section? Could we only set same “ms_async_rdma_device_name”, which means public & cluster network use same rdma device, when deploying Ceph with RDMA? Regards, Changcheng

rgw realm reloader keeps triggering after upgrade to Nautiilus

by Eric Choi

I tried this one in ceph-user, didn't get any response, trying it here again after a slight edit: --- Hello, We recently upgraded from Luminous to Nautilus, after the upgrade, we are seeing this sporadic "lock-up" behavior on the RGW side. What I noticed from the log is that it seems to coincide with rgw realm reloader. What we are seeing is that realm reloader tries to pause frontends for that time period RGW is completely locked up, unable to take new requests. I believe this is an expected behavior. But why does rgw realm reloader keep triggering? is there a way to disable it or reduce frequency? We are not using multi-site feature (although we have a default realm) and we don't change our realm config at all. I captured the log below to see to capture anything with 'watch', Anyone? -- 2019-09-19 18:03:23.245 7f0bd5f5f700 1 rgw realm reloader: Resuming frontends with new realm configuration. 2019-09-19 18:03:23.245 7f2bd8f5d700 1 ====== starting new request req=0x7f2bd8f56950 ===== 2019-09-19 18:03:23.245 7f2bd2750700 1 ====== starting new request req=0x7f2bd2749950 ===== 2019-09-19 18:03:23.245 7f2bcaf41700 1 ====== starting new request req=0x7f2bcaf3a950 ===== 2019-09-19 18:03:23.245 7f2bd074c700 1 ====== starting new request req=0x7f2bd0745950 ===== 2019-09-19 18:03:23.245 7f2bc6f39700 1 ====== starting new request req=0x7f2bc6f32950 ===== 2019-09-19 18:03:23.245 7f2bd5756700 1 ====== starting new request req=0x7f2bd574f950 ===== 2019-09-19 18:03:23.245 7f2bc4f35700 1 ====== starting new request req=0x7f2bc4f2e950 ===== -- 2019-09-19 18:05:41.588 7f2bd2750700 2 req 121303 0.001s s3:get_obj verifying op params 2019-09-19 18:05:41.588 7f2bd2750700 2 req 121303 0.001s s3:get_obj pre-executing 2019-09-19 18:05:41.588 7f2bd2750700 2 req 121303 0.001s s3:get_obj executing 2019-09-19 18:05:41.588 7f2bd2750700 2 req 121303 0.001s s3:get_obj completing 2019-09-19 18:05:41.588 7f2bd2750700 2 req 121303 0.001s s3:get_obj op status=0 2019-09-19 18:05:41.588 7f2bd2750700 2 req 121303 0.001s s3:get_obj http status=200 2019-09-19 18:05:41.588 7f2bd2750700 1 ====== req done req=0x7f2bd2749950 op status=0 http_status=200 latency=0.001s ====== 2019-09-19 18:05:41.588 7f2bd2750700 1 civetweb: 0x7f2c36d6f3a8: 168.245.88.23 - - [19/Sep/2019:18:05:39 +0000] "GET /kamta-incoming/filter0190p3mdw1-28304-5D83C374-LIfsCi4hQiGpa_pXeRjZ-A HTTP/1.1" 200 17578 - Minio (linux;
