Hi, I've still problems to understand the pooling definition Size/min in ceph and what it means to us.
We've a 3 node cluster with 4 SSDs (the smallest sinfull setup in the documention). When I define a ceph pool with 3/2, all implied images requiere the triple storrage. When I define a ceph pool with 2/1, all implied images requiere the double storrage. Means the Size/min the quantity of knodes, over wich the data is distributed? But when I take a knode in maintenance, on the 3/2 setup are still 2 units of each images available, on 2/1 maybe only one. On a 3/2 setup the filesystem get readonly when 2 nodes are down in the same time, on a 2/1 setup it could be the storage is not available any more? I try to understand the impact for us, when we set two pools, one with 3/2 for important VMs and one with 2/1 for VMs wich could stand a while off, or 've no claim to be every time up to date or so,....
