I can confirm this resolved my issue - I tested several times by 'kill -9' an instance before and after the config change to client.cinder Ceph permissions.
*** WARNING!!! If you make the change manually, as I did, be careful because you need to explicitly define all permissions for the client.cinder user as it overwrites all current permissions. For reference, I issued: ceph auth caps client.cinder mon 'allow r, allow command "osd blacklist"' osd 'allow class-read object_prefix rbd_children, allow rwx pool=volumes, allow rwx pool=vms, allow rx pool=images' mds '' This retained all existing permissions. You may need to change your pool names and Ceph user. Thanks for the help James, very useful. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1773449 Title: VM rbd backed block devices inconsistent after unexpected host outage To manage notifications about this bug go to: https://bugs.launchpad.net/charm-ceph-mon/+bug/1773449/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
