Thanks for the info. Yeah, we did exactly that (observe and adjust setting accordingly). Is this something worth mentioning in the documentation? Escpecially when this "factor" is a constant? Over time (with issue 21402 being worked on) things will change. Ceph operators will want to make use of as much cache as possible without overcommitting (MDS won't notice until there is no more memory left, restart, and looses all its cache :/). Gr.
