Hi,
I'm using Queens cinder with the following setting.
--------------------------------- [coordination] backend_url = file://$state_path ---------------------------------
As a result, the files like the following were remained under the state path after some operations.[1]
cinder-63dacb3d-bd4d-42bb-88fe-6e4180164765-delete_volume cinder-32c426af-82b4-41de-b637-7d76fed69e83-delete_snapshot
In my understanding, these are lock-files created for synchronization by tooz. But, these lock-files were not deleted after finishing operations. Is this behaviour correct?
[1] e.g. Delete volume, Delete snapshot
This is a known bug that's described here: https://github.com/harlowja/fasteners/issues/26 (The fasteners library is used by tooz, which is used by Cinder for managing these lock files.) There's an old Cinder bug for it here: https://bugs.launchpad.net/cinder/+bug/1432387 but that's marked as "Won't Fix" because Cinder needs it to be fixed in the underlying libraries. Thanks, Eric
