yes,My cinder driver is LVM+LIO.I have upload the test result in appendix.Can you show me your test results?Thank you!

The other option would be to not use Cinder volumes so you just use local storage on your compute nodes. Readding the block device driver is not likely an option. __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
