[ceph-users] cephfs mount with kernel driver

I noticed that in my scenario, when I mount cephfs via the kernel module, it directly copies to one or three of the OSDs. And the writing speed of the client is higher than the speed of replication and auto scaling This causes the writing operation to stop as soon as those OSDs are filled, and the error of free space is not available What should be done to solve this problem? Is there a way to increase the speed of scaling or moving objects in OSD? Or a way to mount cephfs that does not have these problems?
