====== Save and Remove Cinder Volume Stuck ======

  * Find using openstack command the volume stuck and the file associated to it:
<code bash>
cinder list --all-tenants
</code>

  * Determine from the project or the user the volume. We suppose the file is:
<code bash>
/brickOpenstack/cinder-prod/mpathb/volume-2a367882-9bd7-4ee1-a99e-fa491bcaf0af
</code>

  * Mount the file in a specific path:
<code bash>
mount -t ext4 -o loop,ro,noload /brickOpenstack/cinder-prod/mpathb/volume-2a367882-9bd7-4ee1-a99e-fa491bcaf0af /mnt/cinderDisk
</code>

  * Create a tar with the contents of the directory just mounted:
<code bash>
cd /mnt/cinderDisk
tar -czvf /root/fileBuild20150715.tgz *
</code>

  * Copy the file in a secure zone where the user have access, for example in a nfs export. 
<code bash>
scp fileBuild20150715.tgz root@cld-storage-01:/data/brickOpenstack/muon-steel/sdb/cloud
</code>

  * Send a mail to the user and the cloud-support where the file has been copiated. 

  * To erase the volume from cld-ctrl-01 enter in mysql and execute this query:
<code bash>
mysql> select * from cinder_prod.snapshots where volume_id =
'2a367882-9bd7-4ee1-a99e-fa491bcaf0af';
