"[…] we observed that the df command shows higher space utilization compared to du when many small files are copied. Over time, the outputs of both df and du converge. This happens because #XFS initially reserves additional space for these files.

The feature that causes this behavior is Dynamic Speculative End of File (EOF) Preallocation. This feature allows files to dynamically reserve more space to prevent fragmentation in case the file is grown later on. This blog post explores what this feature is, how it works, and how it can be beneficial for certain use cases. […]"

@janl The purpose is to warn bystanders to invest in technological #complexity that seems to be very attractive for its advanced features without acknowledging the risks or efforts associated.

Its learning curve doesn't even allow for an easy start.

As with so many awesome tools, this is something for specific experts and not for new/occasional/advanced users.

BTDT and I've had my fair share of bad experiences.

Current pain in my setup: #NixOS. Instead of providing an abstraction layer to keep away certain OS setup & maintenance problems for good, I got into so many little & bigger troubles that I try to tell people only to use it when they are ready to invest its required learning effort all the way.

From my point of view, this also holds true for "advanced" file systems like #ZFS, #XFS, ... YMMV.

#Debian question: my systems are all using the... not-non-user-hostile... defaults of encrypted LVM partitions, so I have ~250MB of /boot with #ext4. My / is #XFS so I can't move /boot. I have closed #nvidia drivers via #dkms, maybe that matters.

I used to be able to juggle two kernels, one installed, one to be installed. That fails now, I am stuck.

Are there any good and modern docs on reducing #linux #kernel footprint in /boot?

I can find old stuff, empty stuff, and whataboutism, no docs...

Been reading up a bit trying to decide which file system I want to use when I redo my home server soon. Think I'm leaning towards giving btrfs a go. Curious what the splits are on fedi. I've only ever used ext4 on Linux. I'm guessing for desktop/home server use, xfs isn't very popular. Just including it here since it's in this article.

2/ Ohh, #Btrfs maintainer Josef Bacik replied and among others addressed the many rude remarks from Kent: lore.kernel.org/all/2024100714

Josef among others praises the #XFS and #Ext4 developers and criticises dragging other people and their projects down – and calls the latter a sort of behaviour that he thinks should have no place in this community.

Go and read it in full, quoting from it would not do this great post justice.

Many thx for it, @josefbacik! 👏

[edit] thanks, you can stop now - i've got the right peoples' attention \o/

Looking for a kernel developer who'd be interested to (freelance) help us fix a bug in the mm/xfs area in exchange for €. We're stuck on 5.15 because that little bugger started in 6.1, is apparently still there, regularly produces data loss and is hard to reproduce.

(Sorry for posting a second time, the first one was in German and I guess that wasn't too much of a smart move.) #linux #kernel #xfs
