Public bug reported:

 It will do  clean for evacuated instances  in method init_host in  nova/compute/manager.py  we restart  a failed compute node .
  while using  volume-backend  shared-storage (like ceph) ,   nova leaves instance path directory in failed compuet node.

The root cause  is that we only  passed  argument "destroy_disks"  to driver.destroy,  the value will be true while using ceph.
then will not delete instance path .


This may lead  live-migration  instance  failure with exeption DestinationDiskExists
