You can colocate mons on OSDs as long as you have enough RAM - you may need to run a third mon somewhere else to have a quorum. Also, 2 node cluster isn't recommended at all. 3 for testing is fine or a backup/replication site, better 5 or more. > 3. if i have a 3 physically node osd cluster, did i need 5 physicall mons? No, you'll be fine with 1 or 3 mons (although 1 would be risky) > 3. where i should in install the mgr? on osd or mon You could put the mgr on a osd, it is used mostly for statistics and some housekeeping tasks, but not "critical". > 4. where i should in install the rgw? on osd or mon OR on 1 or 2 separate machines? I don't run RGW so I won't comment. _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
