ceph-osd-replication-count:
|
|
default: 3
|
|
type: int
|
|
description: |
|
|
This value dictates the number of replicas ceph must make of any
|
|
object it stores withing the cinder rbd pool. Of course, this only
|
|
applies if using Ceph as a backend store. Note that once the cinder
|
|
rbd pool has been created, changing this value will not have any
|
|
effect (although it can be changed in ceph by manually configuring
|
|
your ceph cluster).
|
|
ceph-pool-weight:
|
|
type: int
|
|
default: 40
|
|
description: |
|
|
Defines a relative weighting of the pool as a percentage of the total
|
|
amount of data in the Ceph cluster. This effectively weights the number
|
|
of placement groups for the pool created to be appropriately portioned
|
|
to the amount of data expected. For example, if the ephemeral volumes
|
|
for the OpenStack compute instances are expected to take up 20% of the
|
|
overall configuration then this value would be specified as 20. Note -
|
|
it is important to choose an appropriate value for the pool weight as
|
|
this directly affects the number of placement groups which will be
|
|
created for the pool. The number of placement groups for a pool can
|
|
only be increased, never decreased - so it is important to identify the
|
|
percent of data that will likely reside in the pool.

Setting this to True will configure services to log to syslog.

Optionally restrict Ceph key permissions to access pools as required.

Optionally specify an existing rbd pool that cinder should map to.
