<br>
there are a couple of questions rising up:<br>
<br>
- what do you mean by "disks are not added"? Does the server recognize them? Do you see them in the output of "lsblk"?<br>
- Do you already have existing physical volumes for cinder (assuming you deployed cinder with lvm as in the provided link)?<br>
- If the system recognizes the new disks and you deployed cinder with lvm you can create a new physical volume and extend your existing volume group to have more space for cinder. Is this a failing step or someting else?<br>
- Please describe more precisely what exactly you tried and what exactly fails.<br>
<br>
The failing neutron-l3-agent shouldn't have to do anything with your disk layout, so it's probably something else.<br>
<br>

Hai,<br>
<br>
I am installing Openstack Queens on Ubuntu Server.<br>
<br>
My server has extra hard disk(s) apart from main hard disk where OS(Ubuntu)<br>
is running.<br>
<br>
(<br>
<a href="https://docs.openstack.org/cinder/queens/install/cinder-storage-install-ubuntu.html" rel="noreferrer" target="_blank">https://docs.openstack.org/cin<wbr>der/queens/install/cinder-stor<wbr>age-install-ubuntu.html</a><br>
)<br>
As suggested in cinder (above link), I have been trying to add the new hard<br>
disk but the other hard disks are not getting added.<br>
<br>
Can anyone tell me , what am i missing to add these hard disks?<br>
<br>
Other info : neutron-l3-agent on controller is not running, is it related<br>
to this issue ? I am thinking it is not related to this issue.<br>
<br>
I am new to Openstack.<br>
<br>
