My focus is on the SSD ... should it be partitioned(sdf1,2 ,3,4) and shared by the four OSDs on a host? or is this a better configuration for the SSD to be just one partition(sdf1) while all osd uses that one partition? > > my setup: > > - 6 Servers with one 250gb boot disk for OS(sda), > > four-2Tb Disks each for the OSDs i.e Total disks = 6x4 = 24 disks (sdb -sde) > > and one-60GB SSD for Osd Journal(sdf). > > -RAM = 32GB on each server with 2 GB network link. > > hostname for servers: Server1 -Server6 > > Charles, > > What you are describing on the ceph.conf below is definitely not a good > idea.
