Dear Duncan, Thanks for your reply. My rootwrap.conf is correct, but I find there is a garbage file at /etc/cinder/rootwrap.d/ folder. When I remove it, everything is right.
May I ask you another question that how cinder choose volume node to create volume if I have multi volume nodes? For example, when controller node and compute node are alive, the volume will be created at compute node. When I shutdown compute node, the volume will be created at controller node. How can I create volume at compute node when both controller node and compute node are alive?

It still has “Error encountered during initialization of driver: LVMISCSIDriver” error message in cinder-volume.log, how to fix this issue? 2. From cinder-scheduler.log, it shows “volume service is down or disabled. (host: Compute)”. How can I modify cinder.conf to create cinder volume at controller node? The good news is that you only have one problem. The driver not being initialized means that that cinder-volume service never signs on with the scheduler, so is never eligible to create volumes. The problem you need to fix is this one: 2014-07-15 15:01:59.147 13901 TRACE cinder.volume.manager Stderr: 'Traceback (most recent call last):\n File "/usr/bin/cinder-rootwrap", line 10, in <module>\n sys.exit(main())\n File "/usr/lib/python2.7/dist-packages/oslo/rootwrap/cmd.py", line 107, in main\n filters = wrapper.load_filters(config.filters_path)\n File "/usr/lib/python2.7/dist-packages/oslo/rootwrap/wrapper.py", line 119, in load_filters\n for (name, value) in filterconfig.items("Filters"):\n File "/usr/lib/python2.7/ConfigParser.py", line 347, in items\n raise NoSectionError(section)\nConfigParser.NoSectionError: No section: \'Filters\'\n' It looks like the config file /etc/cinder/rootwrap.conf has become corrupted on one node - can you compare this file between the working and not working node and see if there are any differences?
