Hi Ronivon Costa,<br><br>Besides updating volumes table, you should update block_device_mapping table at the same time which manages the mapping between volumes and instances.<br>Using the below commands update these two tables and you can reboot your instances and reattach your volume as normally with your nova command line or dashbord.<br>
<br>mysql -unova -p$PW nova -e "update volumes set status = 'available', attach_status = 'detached', mountpoint = null where id = $ID"<br>mysql -unova -p$PW nova -e "update block_device_mapping set deleted_at = now(), deleted = 1 where volume_id = $ID and deleted = 0"<br>
<br>Good Luck.<br><br><br><div class="gmail_quote">2012/11/19 Ronivon Costa <span dir="ltr"><<a href="mailto:ronivon.costa@gmail.com" target="_blank">ronivon.costa@gmail.com</a>></span><br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

</div><div><br></div><div>Thanks to livemoon, I can get the instances back running following his tips. By the way, I have put that in a shell script below, to make it easy to run the procedure.</div><div><br></div><div>To run, you should type:</div>
<div>restore-instance <instance name><br></div><div><br></div><div>After that, we have the instance running and the database status update.</div><div><br></div><div>The volume attachment still is missing. I can get it to work after a reboot in the host.</div>
<div>As I said in a previous email, the attach was reporting and error that device /dev/vdc was already in use (what is not the case.. it must be a bug or something in the code).</div><div>I changed the device to /dev/vde and it accepts and submit the command, but does not attach the device. Logs are below.</div>
<div><br></div><div>Hope someone - including you livemoon :) - still has something else to say about this.</div><div><br></div><div>Have anyone of you guys tested this before? Does it work for you?</div><div><br></div><div>
