Hi, did you configure the additional MGR(s) as well with server_addr, server_port and certs [0]? I haven't used the restful module before, but it works for me on Squid after creating a self-signed cert and a user/key. Then I used the existing crt (it's a test environment) and set the config-key for the other mgr as well: # get cert and key ceph config-key get mgr/restful/nautilus/crt > nautilus-restful.crt ceph config-key get mgr/restful/nautilus/key > nautilus-restful.key # set cert and key ceph config-key set mgr/restful/nautilus2/crt -i nautilus-restful.crt ceph config-key set mgr/restful/nautilus2/key -i nautilus-restful.key # configure per host server_addr and server_port ceph config set mgr mgr/restful/nautilus/server_addr 192.168.168.111 ceph config set mgr mgr/restful/nautilus/server_port 8003 ceph config set mgr mgr/restful/nautilus2/server_addr 192.168.168.112 ceph config set mgr mgr/restful/nautilus2/server_port 8003 # restart restful if necessary ceph restful restart ceph mgr services | grep rest "restful": "https://192.168.168.111:8003/" # after failover ceph mgr services | grep rest "restful": "https://192.168.168.112:8003/" Hope this helps!

Hi,

I'm doing cluster monitoring using the restful api on the ceph-mgr on port 8003. The requests are working fine as long as I have my *mgr-0* as primary. Doing a `ceph mgr fail` so that the *mgr-1* becomes active, the mgr daemon doesn't listen on port 8003.

Is there any workaround for this? _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-leave@ceph.io
