[ceph-users] how to set load balance on multi active mds?

Hi, experts, we have a product env build with ceph version 16.2.11 pacific, and using CephFS. Also enable multi active mds(more than 10), but we usually see load unbalance on our client request with these mds. see below picture. the top 1 mds has 32.2k client request. and the last one only 331. this always lead our cluster into very bad situation. say many MDS report slow requests… ... 7 MDSs report slow requests 1 MDSs behind on trimming … So our question is how to set those mdss load balance? Could any one please help to shed some light here? Thanks a ton! Thanks, xz
