Hi there,

i created a Cephcluster with 6 OSDs. Each OSD has 500GB

In Proxmox I created a Pool with Size 2 Min 1.
Ceph df shows me I can use round about 1300GB Disk space.
Now I wanted to understand what Size and Min means.

I think Size means duplicate 2 times – that’s the reason why I can use only the half of 2700GB which also means I can break 3 HDDs.
But what means Min? I also can’t find anything in the documentation.
