`ceph-ansible/group_vars`_.
If a parameter to override is not an available group variable, then
global settings in the `ceph.conf` may be set directly using
`ceph.conf` sections settings may be set directly using
`CephConfigOverrides` like the following::
parameter_defaults:
CephConfigOverrides:
max_open_files: 131072
global:
max_open_files: 131072
osd:
osd_journal_size: 40960
To change the backfill and recovery operations that Ceph uses to
rebalance a cluster, use an example like the following::
parameter_defaults:
CephConfigOverrides:
osd_recovery_op_priority: 3
osd_recovery_max_active: 3
osd_max_backfills: 1
global:
osd_recovery_op_priority: 3
osd_recovery_max_active: 3
osd_max_backfills: 1
