Hi Jean-Charles ,

I will validate this config in my laboratory and production, and share the
results here.

Thanks.

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.

JC

[ceph-users] Doubts about parameter "osd sleep recovery"

2019-02-18 Thread Fabio Abreu 
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 :
http://lists.ceph.com/pipermail/ceph-users-ceph.com/2018-March/025574.html

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'
