<br>
</span>IMHO, tke key to resolve this problem is to look back on cinder-scheduler.log where you see this error:<br>
<span class=""><br>
<br>
>> Failed to schedule_create_volume: No valid host was found.<br>
<br>
</span>Also looking on your cinder.conf, you seem to be using LVM over iSCSI as a storage, is that correct?<br>
"No valid host was found" probably means some cinder or iSCSI misconfiguration, ie:<br>
<br>
<br>
<br>
1.I don't see any LVM filters in your config so schedululer may be confised<br>
2. double check if your hosts really have woorking iSCSI access to your storage? this is often source of many problems<br>
<br>
<br>
