HI, Nathan, thanks for your quick reply!
comand 'ceph status' outputs warning including about ten clients failing to
respond to cache pressure;
in addition, in mds node, 'iostat -x 1' shows drive io usage of mds within five
seconds as follow,
You should run this iostat -x 1 on the OSD nodes ... MDS is not doing
any IO in and of itself as far as Ceph is concerned.
