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.
