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.
