I have a small ceph 0.72.2 cluster built with ceph-deploy and running on ubuntu 12.04, this cluster is used as primary storage for my home openstack sandbox.
On one node, when I run any ceph command that interacts with the cluster, I get the appropriate output, but "None" is prepended to it.
root@os2:/etc/ceph# ceph health
None
HEALTH_OK
root@os2:/etc/ceph# ceph
None
ceph>
Again, this only happens on one of the four ceph nodes. I've verified conf files, keys, perms, versions, etc. match on all nodes, no connectivity issues, etc. In fact the ceph cluster is still healthy and working great with only one exception. Cinder-Volume also runs on this node and since "None" is also getting prepended to json formatted output, Cinder-Volume errors out in _get_mon_addrs() when json decoder chokes on the response from ceph. (I'll probably throw a quick pre-decode band-aid on that method to get Cinder back online until I can correct this)
here's my config sans radosgw... although it hasn't changed recently.
[global]
fsid = 02a4abf4-3659-4525-bfe8-f1f5ea024030
mon_initial_members = fs1,os1,cortex,os2
mon_host = 10.10.3.8,10.10.3.10,10.10.3.7,10.10.3.20
auth_supported = cephx
osd_journal_size = 1024
filestore_xattr_use_omap = true
public_network = 10.10.3.0/24
cluster_network = 10.10.150.0/24
I've tried everything I can think of, hoping someone here can point out what I'm missing.
Thanks
