Hello Charles Need some more clarification with your setup , Did you mean
1) There is 1 SSD ( 60 GB ) on each server i.e 6 SSD on all 6 servers ? 2) your osd.3 , osd.4 , osd.5 uses same journal ( /dev/sdf2 ) ?

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 [osd.0] host = server1 devs = /dev/sdb osd journal = /dev/sdf1 [osd.1] host = server1 devs = /dev/sdc osd journal = /dev/sdf2 [osd.3] host = server1 devs = /dev/sdd osd journal = /dev/sdf2 [osd.4] host = server1 devs = /dev/sde osd journal = /dev/sdf2 [osd.5] host = server2 devs = /dev/sdb osd journal = /dev/sdf2 ... [osd.23] host = server6 devs = /dev/sde osd journal = /dev/sdf2 Thanks. _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
