<br>When I'm running iscsadm -m node all my openstack-volumes got this strange -1 (node.tpgt = -1). I've tried to create the iscsi target by hand, but I couldnt.<br>
<br>If some could help me! Here is my fulll nova-compute.log: <a href="http://paste.openstack.org/show/28109/" target="_blank">http://paste.openstack.org/show/28109/</a><br>Thanks in advance<br><br><div class="gmail_extra">

<br></blockquote></div>Hi Vibnu,<div><br></div><div>Strange, you're unable to see the target on either of the nodes? I'm assuming your using the default LVM storage back-end. </div><div><br></div><div>Something to look at:</div>
<blockquote style="margin:0 0 0 40px;border:none;padding:0px"><div>"sudo tgtadm --lld iscsi --op show --mode target" - Make sure your target is present (on the cinder node)</div></blockquote><div><br></div><div>
You shouldn't *need* to do this, but to trouble-shoot you could also try:</div><blockquote style="margin:0 0 0 40px;border:none;padding:0px"><div>"sudo iscsiadm -m discovery -p <a href="http://192.168.150.96:3260" target="_blank">192.168.150.96:3260</a> -t st"</div>
