Hi Sage Thanks for your answer I had ceph.conf already adjusted mon_hosts has the list of public ip's of the mon servers but ceph-mon is listening on eth0 instead of the ip listed in mon_hosts also entering [mon.ceph-ceph01] sections with host= and mon_addr= entries did not change this do I have to redeploy the installation, so far I just pushed the new config and restarted the services? Btw. ceph-deploy new ceph01:10.100.214.x ... wont't work as it requires a name not an ip, but in my case ceph01 resolves to the correct ip regards Andi -----Original Message----- From: Sage Weil [mailto:sage@xxxxxxxxxxx] Sent: Freitag, 23.

I assume you used ceph-deploy here? The problem is that when you do ceph-deploy new ceph01 ceph02 ceph03 it is using the ceph01 etc as both the hostname to identify the instance (good) and looking it up via DNS to resolve the IP for the mon_host list (bad, in your case). Try ceph-deploy new ceph01:10.100.214.x ... or ceph-deploy new ceph01:ceph01.myothernetwork.foo.com ... Or, just manually edit the ceph.conf after the 'ceph-deploy new ...' command to get how you want it. sage _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
