Hi all, I have faced same issue and I solved following way. The exact problem is neutron services not able to communicate to the nova services .

How do i solve this issue?

Just Add the admin role to the neutron user command: keystone user-role-add --user neutron --tenant service --role admin

Note: similarly check all the neutron services

After executing keystone related commands, run neutron agent-list for verification

This is look like, disk mount problem

Check your disk weather mount with cinder-volumes or not

Are there any error messages or exceptions in Cinder-volume logs?

@BharatKumarKobagana, your steps are perfect but, it fails in few systems saying "No such File or Directory" during physical volume creation. For that we found a solution where we have to format the file device and then need to be assigned back to loopback device.


  1. Create a 8G loopback device using: dd if=/dev/zero of=NewDrive.img bs=1G count=8

    #Additional Step

  2. Device file format for some ext3 or other: mkfs.ext3 NewDrive.img

  3. Create loop back device: losetup /dev/loop0 NewDrive.img

  4. Then create physical volume on it: pvcreate /dev/loop0

  5. Now you can create volume group: vgcreate "cinder-volumes" /dev/loop0
