Fedora Server uses XFS on LVM by default & you can do CoW with any modern filesystem on top of an LVM thin pool.

And there is also the Stratis project Red Hat is involved in: https://stratis-storage.github.io/

It looks like btrfs is/was the default for just Fedora Workstation. I’m less connected to Red Hat filesystem details than I used to be.

TIL Stratis is still alive. I thought it basically went on life support after the lead dev left Red Hat.

Still no checksumming though...
