Hi David, Thanks for the reply. I'm a little confused by OSD versus PGs in the description of the two options osd_recovery_max_single_start and osd_recovery_max_active .
The ceph webpage describes osd_recovery_max_active as "The number of active recovery requests per OSD at one time." It does not mention PGs. ? Assuming you meant OSD instead of PG, is this a rephrase of your message: "osd_recovery_max_active (default 15)" recovery operations will run total and will be started in groups of "osd_recovery_max_single_start (default 5)" So if I set osd_recovery_max_active = 1 then osd_recovery_max_single_start will effectively = 1 ?
