Re: [ceph-users] ceph-deploy: is it a requirement that the name of each node of the ceph cluster must be resolved to the public IP ?

This [*] is my ceph.conf 10.70.42.9 is the public address And it is indeed the IP used by the MON daemon: [root@c-mon-02 ~]# netstat -anp | grep 6789 tcp0 0 10.70.42.9:6789 0.0.0.0:* LISTEN 3835/ceph-mon tcp0 0 10.70.42.9:33592

check ceph.conf, it controls to which mon IP the client tries to connect. 2018-05-10 12:57 GMT+02:00 Massimo Sgaravatto : > I configured the "public network" attribute in the ceph configuration file. > > But it looks like to me that in the "auth get client.admin"

I configured the "public network" attribute in the ceph configuration file. But it looks like to me that in the "auth get client.admin" command [*] issued by ceph-deploy the address of the management network is used (I guess because c-mon-02 gets resolved to the IP management address) Cheers,

Re: [ceph-users] ceph-deploy: is it a requirement that the name of each node of the ceph cluster must be resolved to the public IP ?

Monitors can use only exactly one IP address. ceph-deploy uses some heuristics based on hostname resolution and ceph public addr configuration to guess which one to use during setup. (Which I've always found to be a quite annoying feature.) The mon's IP must be reachable from all ceph daemons and
