Sounds like the work Nova will have to do is identical to volume update (swap volume). i.e. Change where a disk's backing store is without actually changing the disk.<br>

That's not what I'm hearing. I'm hearing disconnect/reconnect. Only the libvirt driver supports swap volume, but I assume all other virt drivers could support this generically.<span class=""><br>

Multi-attach! There might be more than 1 instance per volume, and we can't currently support volume update for multi-attached volumes.<br>

Good point - cinder would likely need to reject a request to replicate an in-use multiattach volume if the volume has more than one attachment.<div class="HOEnZb"><div class="h5"><br>
