Also the target_max_bytes is calculated on a per PG bas

Hello all,
Over the past few weeks I've been trying to go through the Quick Ceph Deploy
tutorial at:
http://docs.ceph.com/docs/jewel/start/quick-ceph-deploy/
just trying to get a basic 2 OSD ceph cluster up and running. Everything seems

ceph-deploy osd activate c
Oops, I said CentOS 5 (old habit, ran it for years!). I meant CentOS 7. And I'm
running the following Ceph package versions from the ceph repo:
root@ceph02 ~]# rpm -qa |grep -i ceph
libcephfs1-10.2.3-0.el7.x86_64
ceph-common-10.2.3-0.el7.x86_64
ceph-mon-10.2.3-0.el7.x86_64
ceph-release-1-1.el7.noa
Hi Greg...
Just checking this on my case on 10.2.2
I have mds cache size = 200
Current used RAM in the mds is about 9GB
9 GB / 200 is much closer to 4k than 2k for the sum of Inodes / Cdir
and Cdentries.
Maybe the numbers in
