I have a ceph cluster that I manually deployed, and now I am trying to see if I can use ceph-deploy to deploy new nodes (in particular the object gw).
The network configuration is the following:
Each MON node has two network IP: one on a "management network" (not used for ceph related stuff) and one on a "public network",
The MON daemon listens to on the pub network
Each OSD node has three network IPs: one on a "management network" (not used for ceph related stuff), one on a "public network" and the third one is an internal network to be used as ceph cluster network (for ceph internal traffic: replication, recovery, etc)
Name resolution works, but names are resolved to the IP address of the management network.
And it looks like this is a problem. E.g. the following command (used in ceph-deploy gatherkeys) issued on a MON host (c-mon-02) doesn't work:
unless I change the name resolution of c-mon-02 to the public address
Is it a requirement (at least for ceph-deploy) that the name of each node of the ceph cluster must be resolved to the public IP address ?
Thanks, Massimo
