<div style="font-family:"微软雅黑"; line-height:1.6;">I installed the openstack queens use <span style="line-height: 22.4px;">devstack. I want to test the "</span>Cinder Multi-Attach<span style="line-height: 22.4px;">" </span>function
<div><br>
</div>
<div>1. create a multiattach volume</div>
<div>
<div>```</div>
<div># cinder type-create multiattach</div>
<div># cinder type-key multiattach set multiattach="<is> True"</div>
<div># cinder create 10 --name multiattach-volume --volume-type <volume_type_uuid></div>
<div>```</div>
</div>
<div>2. attache the volume to two instances</div>
<div>```</div>
<div># nova volume-attach test01 <volume_uuid></div>
<div># nova volume-attach test02 <volume_uuid></div>
<div>```</div>
<div><img src="cid:DCD455A4-5EDA-44C0-9DA9-877CCF9C679E@mailmaster" naturalheight="339px" naturalwidth="1689px" currentsize="19" style="width: 1142px;"></div>
<div>3. mount the volume , create some file，but the file don't sync between the two instance，It seems that they are two independent volumes</div>
<div><img src="cid:99ABEDC0-DE62-497F-931B-8F5276ADD2E1@mailmaster"></div>
<div><br>
</div>
<div>then test02 create a file，but i cannot find it in test01,The reverse is the same.</div>
<div><br>
</div>
<div><img src="cid:C2C7FD23-2B2B-4060-9155-C9AC30953580@mailmaster"></div>
<div><br>
</div>
<div>I think i have something wrong，the test like the "share storage"</div>
<div>What should the correct effect be like? thanks</div>
