If RBD backend is used for Nova ephemeral storage, Nova tries to remove ephemeral storage volume from Ceph in a retry loop: 10 attempts at 1 second intervals, totaling 10 seconds overall - which, due to a thirty second ceph watcher timeout, might result in intermittent volume removal failures on Ceph side. This patch adds params rbd_destroy_volume_retries, defaulting to 12, and rbd_destroy_volume_retry_interval, defaulting to 5, which multiplied, give Ceph reasonable amount of time to complete the operation successfully.

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
