Description John Fulton 2018-04-18 17:42:51 UTC
In the Hyper-Converged Infrastructure Guide section 4.2 Reduce Ceph Backfill and Recovery Operations [1], the following is wrong: 

parameter_defaults:
  CephAnsibleExtraConfig:
    osd_recovery_op_priority: 3 # 1
    osd_recovery_max_active: 3 # 2
    osd_max_backfills: 1 # 3

Instead it should read 

parameter_defaults:
  CephConfigOverrides:
    osd_recovery_op_priority: 3
    osd_recovery_max_active: 3
    osd_max_backfills: 1

Note the use of CephConfigOverrides in place of CephAnsibleExtraConfig. Please ensure that the OSP13 document has the same fix.
