No, your available space hasn't increased. If you start with 1 host at let's say 100TB capacity and size 1, your available space is at most 100TB (ceph will actually not allow you to fill drives to 100% by default) - Available capacity = raw capacity If you now add a second host also with 100TB capacity and increase pool size to 2, your available space is still 100TB because all your data is now stored twice - Available capacity = raw capacity / 2 If you go to 3 nodes and size 3 (which you should if you value your data) then available capacity will still only be 100TB because all your data is stored 3x - Available capacity = raw capacity / 3 Only if you add more nodes and keep the replication factor at 3 your available space will increase. A bit simplified but that's what it boils down to. On Fri, 28 Feb 2025 at 06:48, quaglio@bol.com.br <quaglio@bol.com.br> wrote:
Hello, I recently installed a new cluster.
After the first node was working, I started transferring the files I needed. As I was in some urgency to do rsync, I enabled size=1 for the CephFS data pool. After a few days, when I managed to place a new node, I put size = 2 for that pool.
Replicas of existing objects are already being recorded, but the available space has not yet been updated.
The available space should automatically increase as I add more disks. Right?
Could you help me identify where I'm going wrong?
