In Cinder we always try to have sane defaults, but the current RBD default for rbd_exclusive_cinder_pools may lead to issues on deployments with a large number of volumes: - Cinder taking a long time to start. - Cinder becoming non-responsive. - Cinder stats gathering taking longer than the gathering period. This is cause by the driver making an independent request to get detailed information on each image to accurately calculate the space used by the Cinder volumes. With this patch we change the default to make sure that these issues don't happen in the most common deployment case (the exclusive Cinder pool).

upgrade:
|
|
- |
|
|
Ceph/RBD volume backends will now assume exclusive cinder pools, as if they
|
|
had ``rbd_exclusive_cinder_pool = true`` in their configuration.
|
|
|
|
This helps deployments with a large number of volumes and prevent issues on
|
|
deployments with a growing number of volumes at the small cost of a
|
|
slightly less accurate stats being reported to the scheduler.
|
|
fixes:
|
|

|
Ceph/RBD: Fix cinder taking a long time to start for Ceph/RBD backends.
