Hi, I'm not sure if there's a way to predict that, but maybe you're searching for the rbd qos settings [0]? You can either set it on image or pool level, on the command line [1]: rbd config image set <pool>/<image> rbd_qos_iops_limit <value> rbd config pool set <pool> rbd_qos_iops_limit <value> You can also edit those values in the dashboard.

Hello,

AFAIK, massive rx/tx occurs on the client side for the flatten operation. so, I want to control the network rate limit or predict the network bandwidth it will consume. Is there any way to do that? _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-leave@ceph.io
