[ceph-users] Re: How to deal with increasing HDD sizes ? 1 OSD for 2 LVM-packed HDDs ?

The question here is a rather simple one: when you add to an existing Ceph cluster a new node having disks twice (12TB) the size of the existing disks (6TB), how do you let Ceph evenly distribute the data across all disks ?

Ceph already does this. If you have 6TB+12TB in one node you will see that the 12TB will get more data (at least on Nautilus)
