Hi Patrick, many thanks for clarifying this - very useful :) I'm sure a whole lot of people would love to retrospectively move the default from an EC to replicated pool, so +1 from us too. Our cluster uses a 4PB 8:2 EC pool for cephfs data, and a 900GB replicated NVME pool for metadata. Presumably all writes put a footprint on the EC pool? thanks again, Jake
Also, is it possible to insert a replicated data pool as the default on an already deployed CephFS, or will I need to create a new FS and copy the data over?
You must create a new file system at this time. Someday we would like to change this but there is no timeline.
