oh very nice! I tried it out with "batch --report" options, using 1 sdd and 3 hds. (and ceph nautilus) it gave me this: (snipped a bit) Solid State VG: Targets: block.db Total size: 110.00 GB Total LVs: 3 Size per LV: 36.67 GB Devices: /dev/sdb I had seen various claims here and there about how ceph would just automatically figure things out, but I hadnt seen any real world examples.

It doesn't actually create separate partitions on the block devices. You can run the command and it will give you a preview of what it will do and ask for confirmation. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
