Hello all,<br>
<br>
Per <a href="https://review.openstack.org/#/c/283695/" rel="noreferrer" target="_blank">https://review.openstack.org/#<wbr>/c/283695/</a> multi-attach was disabled<br>
for rbd volumes.<br>
<br>
Does anyone know what features are missing or aren't compatible in rbd<br>
for it to support multi-attach?<br>
<br>
Thanks<br>
Shane<br>

Nova doesn't support multiattach volumes for any Cinder backend. That's being worked by the Nova and Cinder teams but won't be something that's implemented on the Nova side in the Ocata release, and will be a stretch probably for Pike. There are weekly meetings about this though, see:<br>
