Description Vasishta 2016-07-25 13:55:07 UTC

Description of problem:
Couldn't start a new monitor while adding via manual steps to a cluster with customized cluster name

Version-Release number of selected component (if applicable):
ceph version 10.2.2-27.el7cp

How reproducible:
always

Steps to Reproduce:
1.Follow below doc to add a new monitor (via CLI) to a cluster with custom cluster name - in my case, it was 'master': 
Doc : https://access.qa.redhat.com/documentation/en/red-hat-ceph-storage/2/administration-guide/#adding_a_monitor_with_the_command_line_interface (see Section 6.1.3)


Actual results: (After Step 10)

# ceph-mon -i cephqe7 --public-addr 10.70.44.48:6789 --pid-file /var/run/ceph/mon.cephqe7.pid
2016-07-25 18:02:16.348198 7fd7fc03e4c0 -1 did not load config file, using default settings.
monitor data directory at '/var/lib/ceph/mon/ceph-cephqe7' does not exist: have you run 'mkfs'?

Expected results:
Monitor must get started

Additional info:

When mkfs was run (Step 9 same doc) it could successfully create contents of monitor data in directory /var/lib/ceph/mon/master-cephqe7 that is, /var/lib/ceph/mon/<cluster_name>-<node_ID>

# ceph-mon -i cephqe7 --mkfs --monmap /tmp/ceph/ceph_mon_map.out --keyring /tmp/ceph/ceph_keyring.out -c /etc/ceph/master.conf
ceph-mon: set fsid to bca06dbe-9499-4dc3-9cb2-92717274848f
ceph-mon: created monfs at /var/lib/ceph/mon/master-cephqe7 for mon.cephqe7


But when an attempt is made to start monitor as mentioned above, It is expecting contents of monitor data to be present in var/lib/ceph/mon/ceph-cephqe7 that is, var/lib/ceph/mon/ceph-<node_ID> instead of /ceph/mon/<cluster_name>-<node_ID>

ceph-mon -i cephqe7 --public-addr 10.70.44.48:6789 --pid-file /var/run/ceph/mon.cephqe7.pid
2016-07-25 18:02:16.348198 7fd7fc03e4c0 -1 did not load config file, using default settings.
monitor data directory at '/var/lib/ceph/mon/ceph-cephqe7' does not exist: have you run 'mkfs'?

You didn't specify the master.conf config file...  This seems to be the correct behavior.

Comment 3 Vasishta 2016-07-25 15:09:14 UTC

Hi Samuel,

Yes, I didn't mentioned about conf file.

Correct version I must have used is -
ceph-mon -i cephqe7 --public-addr <IP addr:Port> --pid-file /var/run/ceph/mon.cephqe7.pid -c /etc/ceph/master.conf
Working perfect.

Extremely Sorry.


Thanks,
Vasishta P Shatsry
