Comment 29 for bug 1718295

hi , because of power outage, Most of our compute nodes unexpectedly shut down and now I can't start our instances. I am getting "Failed to get "write" lock Is another process using the image?" error. Full error log is http://paste.openstack.org/show/754107/. My environment is OpenStack Pike and Instances are on a nfs shared storage. Nova version is 16.1.6.dev2. This fix can not solve this problem completely. What would you suggest for solve this problem ?
