Fedora Server 22 Is Using The XFS File-System By Default
Using the XFS file-system as the default within an LVM has been part of the Fedora Server technical spec while with Fedora 22 it's finally happened. The default layout for Fedora Server 22 installations is using XFS atop LVM while /boot is outside the LVM setup.
Fedora Server defaulting to XFS isn't too much of a surprise considering XFS has a lot of uptake within server/workstation deployments, it's very mature, and RHEL 7.x switched to defaulting to XFS over EXT4. Of course, via the Anaconda installer you can still change the file-system in use for any version of Fedora Linux.
In Fedora 23~24 we may see the main Fedora Workstation product switch over to Btrfs by default while the Fedora Server version will likely stick with XFS given that it's much more mature, doesn't run into any performance issues with databases or other areas where the copy-on-write Btrfs design struggles, etc.
Fedora Server defaulting to XFS was talked about during today's Fedora Server SIG meeting along with other new features of the database server role, the Cockpit management console now being compatible across OS-releases, DNF as the default package manager, Ipsilon as a new multi-protocol identifier provider service, and the Fedora Server supporting Docker containers on ARMv7hl.
