Also we want share the files between two datacenter (dark fiber with 10Gbit) (but keep both Ceph clusters separate). So I think, we put three MDS in VMs on our Proxmox VM cluster (5 nodes) with a bit RAM and check, if it is reliable. Its much more complicated to have a shared storage for "legacy" systems, than we thought :-) Also RadosGW with NFS is on Debian Stretch not the first choice, as NFS does not has the features, we need (or my Google was to old). cu denny _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
