<p class="MsoNormal"><span style="font-size:9.5pt">Hi all,</span><u></u><u></u></p>
</div>
<div>
<p class="MsoNormal"><span style="font-size:9.5pt">I was wondering if there was any way to cleanly detach volumes from failed nodes. In the case where the node is up nova-compute will call Cinder's terminate_connection API with a "connector" that includes
information about the node - e.g., hostname, IP, iSCSI initiator name, FC WWPNs, etc.</span><u></u><u></u></p>
</div>
<div>
<p class="MsoNormal"><span style="font-size:9.5pt">If the node has died, this information is no longer available, and so the attachment cannot be cleaned up properly. Is there any way to handle this today? If not, does it make sense to save the connector
elsewhere (e.g., DB) for cases like these?</span><u></u><u></u></p>
