<div dir="ltr"><div>Hi folks,</div><div> Because of power outage, Most of our compute
nodes unexpectedly shut down and now I can not start our instances. Error message is "Failed to get "write" lock another process using the image?".
Instances Power status is No State. Full error log is <a href="http://paste.openstack.org/show/754107/" rel="nofollow">http://paste.openstack.org/show/754107/</a>.
My environment is OpenStack Pike on Ubuntu 16.04 LTS servers and Instances are on a nfs shared
storage. Nova version is 16.1.6.dev2. qemu version is 2.10.1. libvirt version is 3.6.0. I saw a commit , but it doesn't solve this problem.</div><div>There are important instances
on my environment. How can I rescue my instances? What would you suggest
?</div><div><br></div><div>Thanks,</div><div>Gökhan</div><div><br></div><div> <a href="https://review.opendev.org/#/c/509774/">https://review.opendev.org/#/c/509774/</a></div></div>
