I have successfully installed Luminous on Ubutnu 16.04 by one network.
Now I am trying to install same by using two networks
this.(on different machine)
public network
= 192.168.10.0/24
cluster network
= 172.16.50.0/24
Eeach node has two interfaces. One in public network
other in cluster network.
While creating the initial monitors facing the the below error
“Some monitors have still not
reached quorum”
Below is /etc/hosts file on each host
172.16.50.1 mon1
172.16.50.2 mon2
172.16.50.3 mon3
172.16.50.4 osd1
172.16.50.5 osd2
This is ceph.conf
file
mon1:/home/cephadmin/my-cluster# cat ceph.conf
[global]
fsid = 7f0ffa2b-7528-407b-8a63-360741d80939
mon_initial_members = mon1, mon2, mon3
mon_host = 172.16.50.1,172.16.50.2,172.16.50.3
auth_cluster_required = cephx
auth_service_required = cephx
auth_client_required = cephx
# Public and cluster network
public network =
192.168.10.0/24
cluster network =
172.16.50.0/24
# Write an object 2 times
osd pool default size = 2
# 1 for a multi node cluster in a single rack
osd crush chooseleaf type = 1
While searching on net , I found same error discussed in
below post
I am observing same error in my case that during ceph-deploy mon
create-initial all devices name are not
resolving properly.

I configured the DNS also as suggested solution in above link, but issue did not resolve.
Can some one help in this regard?
I am not sue in DNSlooup name should be resolve to node’s public IP or
cluster IP?
In /etc/hosts file which IP of nodes should use cluster or public ?
