Hello, We are running a Ceph cluster with 3x CentOS 7 MON nodes, and after we updated the ceph packages on the MONs yesterday (from 0.94.3 to 0.94.4), the ceph_rest_api started refusing to run, giving the following error 30 seconds after it’s
started: [root@ceph-mon01 ~]# /usr/bin/ceph-rest-api -c /etc/ceph/ceph.conf --cluster ceph -i admin Traceback (most recent call last): File "/usr/bin/ceph-rest-api", line 59, in <module> rest, File "/usr/lib/python2.7/site-packages/ceph_rest_api.py", line 503, in generate_app addr, port = api_setup(app, conf, cluster, clientname, clientid, args) File "/usr/lib/python2.7/site-packages/ceph_rest_api.py", line 145, in api_setup target=('osd', int(osdid))) File "/usr/lib/python2.7/site-packages/ceph_rest_api.py", line 83, in get_command_descriptions raise EnvironmentError(ret, err) EnvironmentError: [Errno -4] Can't get command descriptions: Nothing else was changed, only the packages were updated. I’ve looked at the python, and it seems to be timing out waiting for this line to complete, but I’m not sure where to look next in terms of what “get_command_descriptions” actually
does: ret, outbuf, outs = json_command(cluster, target, prefix='get_command_descriptions', timeout=30) Is this a known issue? If not, does anyone have any suggestions of how to further troubleshoot this further? Thanks in advance.
