I'm not super-plugged into Fedora these days. Red Hat has long been pretty comfortable with a more conventional file system (think it's still XFS out of SGI by default) plus volume management for RHEL. ZFS was a non-starter for licensing reasons and Oracle; btrfs just wasn't there. I suspect things could have played out differently had Oracle relicensed ZFS once upon a time but that ship has likely sailed in a variety of ways.

XFS is a default filesystem in a production system? Really?

XFS was dead to me 20 years ago. The only time I ever actually verifiably lost data to a system crash was on XFS. I had actual zero length files with XFS after a crash. Lost actual data. But the file system was in totally happy consistent metadata state. Never ever would I ever consider that filesystem ever again.

The ominous "reisserfs" everyone complained about? Never lost a single byte of data to it even when I pulled the plug in the middle of a write operation to test it. No issues with ext4, no experience with btrfs.

You may not believe it but it is true: https://docs.redhat.com/en/documentation/red_hat_enterprise_...

I vaguely know some of the backstory of moving off ext4 (as default). As I understood it at the time, it was less focused on some of the larger systems Red Hat was interested in.

The main problem with ReiserFS is Reiser killed his wife so it is unmaintained.

		There is that. I think ReiserSF used to be the default that SUSE used. These days, it seems to be btrfs for root and XFS for everything else.
