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><br>

Multi-attach!

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.</blockquote></div></div></div></div></blockquote><div><div class="gmail_default" style="font-family:monospace,monospace;display:inline">So replication is set on create of the volume, you could have a rule that keeps the two features mutually exclusive, but I'm still not quite sure why that would be a requirement here. </div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div class="HOEnZb"><div class="h5"><div class="gmail_extra"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div class="m_8949244591352267001HOEnZb"><div class="m_8949244591352267001h5"><br>
