Fixed In Version: openstack-tripleo-heat-templates-6.2.1-2.el7ost
Doc Type: Enhancement
Doc Text:
This enhancement allows the Ceph cluster to determine the pool's minimum replica size, by reference to the desired replica size. The director will no longer enforce a minimum replica size of 1 for the Ceph pools; you can instead configure a desired replica size using the `CephPoolDefaultSize` parameter (defaulted to `3`), based upon which the Ceph cluster will identify the optimal minimum replica size. This was changed because enforcing a minimum replica size of 1 is dangerous, as it allows for writes in the Ceph pools when only one copy of the data is available. As a result, the minimum replica size for the Ceph pools is determined by the Ceph cluster, based on the desired replica size of each pool.
