Subject:  [Openstack] How can I make my changes of ceph.conf to take effectin Cinder?



Hello! I'm using Ceph as the backend storage system for Cinder, and I want to change some settings of Ceph client, so I add the following into /etc/ceph/ceph.conf of my compute node A:
[global]
  debug ms = 10
  log file = /var/log/ceph/global.log

[client]
  debug ms = 10
  debug rados = 10
  log file = /var/log/ceph/client.log


but after restarting nova-compute and all the VMs on node A, restarting cinder-volume, cinder-api, cinder-scheduler on Cinder controller node B, I created a new volume and attached it to a VM on node A, but there is still no client.log or global.log after I read or write this new volume! Could any one tell me how can my modification of ceph.conf make difference? I make sure that rbd_ceph_conf=/etc/ceph/ceph.conf in cinder.conf on node B, and the data are written into Ceph cluster.


PS: The [global] section is used just to know whether ceph.conf is useful......


Thanks!
