From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

EXT4 Has A Very Nice Performance Optimization For Linux 6.11 (Phoronix) (www.phoronix.com)

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()."

Sure! I'm interested into the "current" state or real world experience of it. Wouldn't mind if you post it here. Although I am not sure how relevant it is 1 year later, because the filesystem is quite under development.

Here you go: https://drwho.virtadpt.net/archive/2019-11-04/experimenting-with-btrfs-in-production/

That its under development means that it's being maintained. EXT4 is still being developed, so is xfs. And the other ones that are fairly popular, for that matter.

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?

[–] soundconjurer@mstdn.social 1 points 3 months ago (1 children)

@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.

[–] drwho@beehaw.org 1 points 3 months ago

That's entirely fair.
