| Hi Fabio,
have a look here: https://github.com/ceph/ceph/blob/luminous/src/common/options.cc#L2355
It’s designed to relieve the pressure generated by the recovery and backfill on both the drives and the network as it slows down these activities by introducing a sleep after these respectives ops.

Hi Everybody !
I finding configure my cluster to receives news disks and pgs and after configure the main standard configuration too, I look the parameter "osd sleep recovery" to implement in production environment but I find just sample doc about this config.
Someone have experience with this parameter ?
Only discussion in the internet about this :
My main configuration to receive new osds in Jewel 10.2.7 cluster :
Before include new nodes :
$ ceph tell osd.* injectargs '--osd-max-backfills 2'
$ ceph tell osd.* injectargs '--osd-recovery-threads 1'
$ ceph tell osd.* injectargs '--osd-recovery-op-priority 2'
$ ceph tell osd.* injectargs '--osd-client-op-priority 63'
$ ceph tell osd.* injectargs '--osd-recovery-max-active 2'
After include new nodes
$ ceph tell osd.* injectargs '--osd-max-backfills 1'
$ ceph tell osd.* injectargs '--osd-recovery-threads 1'
$ ceph tell osd.* injectargs '--osd-recovery-op-priority 1'
$ ceph tell osd.* injectargs '--osd-client-op-priority 63'
$ ceph tell osd.* injectargs '--osd-recovery-max-active 1'
