We need to enable multiattach on several volume backends, checked cinder source code (Newton release), and found below drivers can support multi-attach function:

  • LVM
  • EMC XtremIO Storage
  • Dell EqualLogic Storage
  • Fujutsu ETERNUS DX S3 Series
  • HPE 3PAR Storage Array
  • IBM FlashSystem Storage Systems
  • NetApp 7-mode Block Storage Systems
  • NetApp c-mode Block Storage Systems
  • NetApp NFS Storage
  • Pure Storage FlashArray Storage Systems
  • ZTE Storage Systems

The question is: What is the plan for other drivers to support multi-attach function, especially for Ceph and NFS if any?

Be aware that nova does not support multi-attach. So cinder multi-attach is not usable yet, no matter what backend you use.
