The problem is, that the LV is not active and because of that, there is no device node (that's why it fails with "No such file or directory")
Steps to reproduce:
1) make sure the provision type for the enabled backend is "lvm_type=thin"
2a) Run tempest test ^tempest.scenario.test_volume_boot_pattern.TestVolumeBootPatternV2.test_volume_boot_pattern
or 2b) call the following commands to trigger the bug:
3) cinder create 1
4) cinder snapshot-create --name snap1 $VOLUME_UUID
5) cinder create --snapshot-id $SNAPSHOT_UUID 1 --name from-snap1 |
