I am using the "ceph-ansible" set of Ansible playbooks to try to get a test cluster up and running (in Vagrant.) I am deploying Mimic (13.2.4) on Ubuntu 16.04, with one (for now) monitor, and three osd servers.
I have a play in the Ansible that is erroring out, and in troubleshooting what that play does manually, I see:
vagrant@mon0:~$ sudo ceph --cluster ceph -n mon. -k /var/lib/ceph/mon/ceph-mon0/keyring mon_status --format json
server name not found: [v2:192.168.42.10:3300 (Name or service not known) unable to parse addrs in '[v2:192.168.42.10:3300,v1:192.168.42.10:6789]'
2019-02-01 04:26:52.446 7f8a66e0e700 -1 monclient: get_monmap_and_config cannot identify monitors to contact [errno 22] error connecting to the cluster
The /etc/ceph/ceph.conf file on mon0 has:
vagrant@mon0:~$ less /etc/ceph/ceph.conf
# Please do not change this file directly since it is managed by Ansible and will be overwritten
[global]
mon initial members = mon0
fsid = 039e920d-5f75-4fa3-aee1-f5a90b073f9e
mon host = [v2:192.168.42.10:3300,v1:192.168.42.10:6789]
public network = 192.168.42.0/24
cluster network = 192.168.42.0/24
If I change the "mon host" line to:
mon host = 192.168.42.10
Then the "mon_status" command works:
vagrant@mon0:~$ sudo ceph --cluster ceph -n mon. -k /var/lib/ceph/mon/ceph-mon0/keyring mon_status --format json
{"name":"mon0","rank":0,"state":"leader","election_epoch":5,"quorum":[0],"features":{"required_con":"144115738102218752","required_mon":["kraken","luminous","mimic","osdmap-prune"],"quorum_con":"4611087854031142907","quorum_mon":["kraken","luminous","mimic","osdmap-prune"]},"outside_quorum":[],"extra_probe_peers":[],"sync_provider":[],"monmap":{"epoch":1,"fsid":"839b40b9-4260-485d-ad74-4c4fbb223689","modified":"0.000000","created":"0.000000","features":{"persistent":["kraken","luminous","mimic","osdmap-prune"],"optional":[]},"mons":[{"rank":0,"name":"mon0","addr":"192.168.42.10:6789/0","public_addr":"192.168.42.10:6789/0"}]},"feature_map":{"mon":[{"features":"0x3ffddff8ffa4fffb","release":"luminous","num":1}],"client":[{"features":"0x3ffddff8ffa4fffb","release":"luminous","num":1}]}}
So, my question is: is the syntax of the "mon host" line that ceph-ansible is generating correct?
