<br>
I've been trying to find some information about using nova resize on<br>
shared storage, without giving each compute node ssh access to every<br>
other compute node. As the VM is on shared storage, the compute node<br>
shouldn't need ssh access to another compute node?<br>
<br>
Is this something that anyone has succeeded in doing?<br>
<br>
I've found the following documentation:<br>
<br>
<a href="http://docs.openstack.org/mitaka/config-reference/compute/resize.html" rel="noreferrer" target="_blank">http://docs.openstack.org/mit<wbr>aka/config-reference/compute/<wbr>resize.html</a><br>
<a href="http://docs.openstack.org/user-guide/cli_change_the_size_of_your_server.html" rel="noreferrer" target="_blank">http://docs.openstack.org/use<wbr>r-guide/cli_change_the_size_<wbr>of_your_server.html</a><br>
<br>
but it does not say what to do in the case of shared storage.<br>
<br>
Cheers,<br>
Marcus.<br>
