Thanks for the input! Changing this value we indeed increased the recovery speed from 20 object per second to 500! Now something strange: 1. We needed to change the class for our drives manually to ssd. 2. The setting "osd_mclock_max_capacity_iops_ssd" was set to 0. With osd bench descriped in the documentation, we configured the value 10000 for the ssd parameter. Only nothing changed. 3. But when setting "osd_mclock_max_capacity_iops_hdd" to 10000, the recovery speed also increased dramatically! I don't understand this anymore :( Is the mclock scheduler ignoring the override of the device class? _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
