Ted Ts’o sent out the EXT4 updates today for Linux 6.11. He explained in that pull request:
“Many cleanups and bug fixes in ext4, especially for the fast commit feature. Also some performance improvements; in particular, improving IOPS and throughput on fast devices running Async Direct I/O by up to 20% by optimizing jbd2_transaction_committed().”
Thanks. But it’s important to note your experience report is based on the experience of 2019 and the slight edits aren’t changing that. That its being developed is not the same as under maintenance. EXT4 is fully developed and there are only optimizations in performance expected, if anything, while BTRFS still needs active development to improve compatibility and some other features.
I’m still curious to how to work with it and such a report is still welcome. I’ll give it a read. Edit: Hopefully my reply didn’t sound too negative. I’m interested in the process of going all of this, so the article is useful in a practical sense.
@thingsiplay @drwho , as soon as RAID5/6 is fully ready (and I am aware it looks like it’ll never be), I’ll be switching over to it.
What’s your use case? Do you need the storage capacity and parity of RAID-5 or -6? The write performance?
@drwho I have a data server with data I hold dear and want to ensure losing drives (using RAID6) won’t lead to me losing my data.
That’s entirely fair.
My experience is based on running that btrfs array since 2019. It’s still running in production on my server, I still use it daily, and the data I keep on it is still accessed, processed, indexed, and backed up every day. It’s not an experiment for the sake of a blog post, it’s a thing that is part of my personal infrastructure. The reason I update that post periodically is because I learn something new, or something minor has changed and the text should be updated to reflect that. If using btrfs on a busy server every day is the experience of 2019, I don’t know what to say to that.
Oh that’s hugely different then. It was not apparent that you were using this setup since the initial blog post. Maybe make a note at the top of the post, so your message (like here) is understood. Don’t get me wrong, I appreciate the clear information you give here and your feedback on how this works. From your report and given its the default FS for Fedora, its absolutely clear that I need to review my bias and view as BTRFS as a contender for my next system drive.
I had intended that the dates on the edits would have suggested otherwise (the last was 20230422), but I also get how easy it is to miss them if you’re looking for something specific. I can’t change the publication datestamp because that’s part of the slug, and it would break links both internal and any that are external.
