All SolidFire Cinder Driver versions between Queens and Ussuri

Issue

This can show up in three possible ways:

  • Element Software did not return a create volume status within 30 seconds to OpenStack
  • OpenStack cinder was able to create two volumes with the same OpenStack name
  • OpenStack Nova was unable to attach to either of the duplicate-OpenStack-named volumes

Example errors from the cinder volume manager log:
