Re: ceph-deploy create-initial errors out with "Some monitors have still not reached quorum"

Hi Maruthi,

and did you test that DNS name lookup properly works (e.g. nslookup ceph-mon1 etc...) on all hosts? 

From the output of 'ceph-deploy' it seem that the host can only resolve it's own name but not the others:

[ceph-mon1][DEBUG ]   "monmap": {
[ceph-mon1][DEBUG ]     "created": "0.000000",
[ceph-mon1][DEBUG ]     "epoch": 0,

[ceph-mon1][DEBUG ]     "modified": "0.000000",
[ceph-mon1][DEBUG ]     "mons": [
[ceph-mon1][DEBUG ]       {

[ceph-mon1][DEBUG ]         "name": "ceph-mon1",

[ceph-mon1][DEBUG ]       },
[ceph-mon1][DEBUG ]       {

[ceph-mon1][DEBUG ]         "name": "ceph-mon2",

[ceph-mon1][DEBUG ]         "rank": 2
[ceph-mon1][DEBUG ]       }
[ceph-mon1][DEBUG ]     ]
[ceph-mon1][DEBUG ]   },


Best,
Martin

hi Wade,

Yes firewalld is disabled on all nodes.

[ceph@ceph-mon1 ~]$ systemctl status firewalld
firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled)
   Active: inactive (dead)

thanks,
Maruthi.

hi fellow users,

I am setting up a ceph cluster with 3 monitors, 4 osds on CentOS 7.1

Each of the nodes have 2 NICs.
10.31.141.0/23 is the public n/w and 192.168.10.0/24 is the cluster n/w.

Completed the "Preflight Checklist".
But in the "Storage Cluster Quick Start", while doing "ceph-deploy create-initial" I see  error "Some monitors have still not reached quorum".
