The default value is 0 which has the minimum number be caluclated based on the replica count from osd_pool_defaut_size. The default replica count is 3 and the calculated min_size is 2. If the replica count is 1 then the min_size is 1. ie: min_size = replica - (replica/2) Add CephPoolDefaultSize parameter to ceph-mon.yaml. This parameter defaults to 3 but can be overriden. See puppet-ceph-devel.yaml for an example Change-Id: Ie9bdd9b16bcb9f11107ece614b010e87d3ae98a9

fixes:
|
|
- |
|
|
Removed the hard coding of osd_pool_default_min_size. Setting this value
|
|
to 1 can result in data loss in operating production deployments. Not
|
|
setting this value (or setting it to 0) will allow ceph to calculate the
|
|
value based on the current setting of osd_pool_default_size. If the
|
|
replication count is 3, then the calculated min_size is 2. If the
|
|
replication count is 1, then the calcualted min_size is 1. For a POC
|
|
deployments using a single OSD, set osd_pool_default_size = 1. See
|

|
|
Added CephPoolDefaultSize to set default replication size. Default value is 3.
