This patch adds block storage troubleshooting documentation, which superseeds the old documentation. It's actually https://review.openstack.org/#/c/49972 - but that patch became a rebase hell, hence the new one. Change-Id: I37621e1bede368b57a5af5e33b2d131c7e28d488

<para>Multipath call failed exit. This warning occurs in the Nova log if you do not have the
|
|
optional <filename>multipath-tools</filename> package installed on the Compute node.
|
|
This is an optional package and the volume attachment does work without the multipath
|
|
tools installed. If the <filename>multipath-tools</filename> package is installed on the
|
|
Compute node, it is used to perform the volume attachment. The IDs in your message are
|
|
unique to your system.</para>
