Ceph Optimal Recovery Values

The Ceph defaults for this are a little too aggressive for most devices, this will give you a more reasonable recovery speed that does not tank the system as hard but still yields a quick stable recovery.

ceph config set osd osd_recovery_sleep_hdd 0.25
ceph config set osd osd_recovery_sleep_ssd 0.05
ceph config set osd osd_recovery_sleep_hybrid 0.10
