Comment 4 for bug 1645624

Thanks Marcus, I looked further at it and found that this filter works:

global_filter = [ "r/dev/cinder/.*/" ]

after this we should do 'update-initramfs -u' in order to ensure that changes are kept during reboot.

So in this way we don't need to care about names of host's disks, we need just know name of Cinder volume group which is created by Fuel during provisioning
