Phoronix: XFS File-System With Linux 5.12 Has "A Lot Going On This Time"

XFS maintainer Darrick Wong characterized the file-system driver changes for Linux 5.12 as "a lot going on this time, which seems about right for this drama-filled year."..

Michael any chance of new ssd fs benchmark round for linux 5.12?

I heard that Rust is going to be allowed in the Linux kernel, then imagine if someone writes a file system in Rust, then maybe we can have a reliable file system without any file system corruption.

uid313 We already have BTRFS, Ext4, XFS and many more. What would be the value of yet another filesystem?

Having a file system that is good. That is reliable, trusted, solid and has features. Btrfs has lots of cool features, but you can't trust it with your data. Ext4 and XFS are stable but they lack features. With Rust maybe we can have a file system that is reliable, but I don't know, maybe Btrfs isn't unreliable because of the language, maybe it has other types of bugs and things like poor design.

To have a filesystem that has the all features of all the ones you listed. ZFS is the only one that does but it's out of tree. Only EXT4 is case insensitive; only F2FS/BTRFS have compression; XFS deletes fast and doesn't shrink. You gotta pick and choose filesystems by features needed because the only real multitool filesystem isn't in-kernel.

I hope they rewrite OpenZFS in Rust and GPL.

Why do people think writing programs / drivers in rust magically solves everything?

filesystem interacts with other pieces of kernel and bugs in software often result from incorrect interaction between pieces. and rust doesn't make programs magically bug free, it can be seen as a silver bullet only by imbeciles like you or by people who never learned language more advanced than c

i can, because i'm smarter than you

. Ext4 and XFS are stable

you can't have stable non-checksummimg fs on bitrotting drive

With Rust maybe we can have a file system that is reliable

did it work well for firefox?

, but I don't know, maybe Btrfs isn't unreliable because of the language, maybe it has other types of bugs and things like poor design.

well, you are correct with first sentence, you don't know. btrfs is reliable, but some of its features are not ready yet(raid5/6). so don't use them, that's all, just as you don't use 100% of unimplemented features of your imaginary rust filesystem

XFS' (lack of) shrink support is the main thing that has stopped me using it all these years.

That said, now we have btrfs I'm not sure if I would bother going back to XFS even if it did pick up shrink support. Maybe if it picked up subvolume support as well.

And yes, for typical laptop uses you *can* trust btrfs with your data, at least on *buntu and Manjaro.
