We've investigated the issue and found that the test failed with timeout because 'lvremove' command executed by cinder-volume service hanged, it's process went to D state.

Rebooting VM hard (via sysrq-trigger) didn't helped - after every reboot cinder volume came back and an attempt to remove it exited in lvremove in D state.

We managed to fix it by downgrading the kernel to 'linux-image-3.13.0-71'. After a reboot (to use new kernel) we removed the volume without any issue.

I'm attaching log files of our attempts to remove the volume with both kernels. The command used:

    strace -f lvremove -f cinder 2>&1 | tee lvremove.log

Log files renamed to match kernel names used.
