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.

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.

  That's why I called it "reisserFS" and not reiserfs. I am well aware of the controversies because of what he did on the non-technical side. I am also of course for a very long time by now not using it any longer. I was merely talking about the experience with XFS "back in the day" and yes I was on reiserfs and then XFS "came up" and I changed my home partition to that, coz I was looking to move off of reisserfs. Power outage. Boom, lost half my home dir. Suddenly lots of totally fine metadata wise files had null length. I did go back to reiserfs until ext4 was stable enough after that. I will never try XFS ever again, sorry. Loosing data is the thing that a file system can't do to me if they want to "retain my business" so to speak. And yes, reiserfs I actually tested and had survive some power outages totally fine too. I believed the XFS hype too much without proper testing. My bad I guess in that sense. We were all young once. But also: Never again XFS ;)

You may not believe it but it is true: https://docs.redhat.com/en/documentation/red_hat_enterprise_linux/7/html/storage_administration_guide/ch-xfs 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.
