Too much pgs backfilling

[Jimmy Goffaux <jimmy@xxxxxxxxxx>]

Hello,

 

This is my configuration :

-> "osd_max_backfills": "1",
-> "osd_recovery_threads": "1"
->  "osd_recovery_max_active": "1",
-> "osd_recovery_op_priority": "3",

-> "osd_client_op_priority": "63",

 

I have run command :  ceph osd crush tunables optimal  

After  upgrade Hammer to Jewel.

 

My cluster is overloaded on : pgs backfilling  : 15  active+remapped+backfilling . ..

 

Why 15 ? My configuration is bad ? normally I should have max 1

 

Thanks
