Hi Martin Thanks for you reply !
Yes I am using
"osd recovery op priority", "osd max backfills", "osd recovery max active" and "osd client op priorit" to trying minimize the impact in the cluster expansion.
My Ceph version is 10.2.7 Jewel and I am moving 1 osd waiting the recovery and go to another one, because I have a history of move an entire storage and this change create slow requests and pg blocking.
I asking this question early to try understand the experience of another ceph admins with this scenario.
Thanks and best Regards,
Fabio Abreu

Hello Fabio,you can use the "osd recovery sleep" option to prevent trouble while recovery/rebalancing happens. Other than that, options like "osd recovery op priority", "osd max backfills", "osd recovery max active", "osd client op priority" and other might help you depending on your cluster version, configuration and hardware.As we believe a good Ceph solution should make your live easier, we have build a option slider within the maintenance view in our software. You can see this in the attached screenshot. Maybe you give it a try!Please feel free to contact us if you need assistance with your cluster.--
