Multipath call failed exit

Problem

Multipath call failed exit. This warning occurs in the Compute log if you do not have the optional multipath-tools package installed on the compute node. This is an optional package and the volume attachment does work without the multipath tools installed. If the multipath-tools 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.
