XFS

That's fascinating.

So Stratus is kind of their red hat solution to ZFS or ButterFS or BcacheFS by trying to kind of stack XFS with LVM and other tooling to kind of replicate some of that functionality with a really nice proven stack.

I mean, it's not a horrible idea.

A lot of good tech involved.

So it turns out what Ubuntu wants to do is greatly restrict the amount of code that goes into grub.

So they want to drop support for JPEG and PNG images, all the exotic file systems like ButterFS, XFS, ZFS, support for Lux encryption, for software RAID other than just mirroring, for HFS and Apple partition table support, All of it.

It's going to strip Grubdown to be just the most basic read the slash boot partition to get your kernel and init ramfs off of basically ext4, FAT, or ISO 9660, which is the CD images.

and squashfs.

And at this point, it seems pretty clear it's never going to get any more time in the oven.

So you really shouldn't be using Canonical's little B pool and R pool setup in the first place.

And to be clear, you can absolutely still have secure boot and you can still use ZFS, Butter, XFS, whatever odd file system you want.

It's just not going to be root file system.

It also has a fix for a buffered write slowdown that was occurring.

Small direct writes got faster on both EXT4 and XFS, and a ByteDance engineer tested it on a PCIe Gen 5 NVMe drive and saw 4K random reads go from about 1.92 million operations per second to 2.19 million, with bigger... bigger gains when you're using IO underscore U ring, which we've talked about in the past.

And for ButterFS, Fsync, the call that makes sure your data actually hits the disk can be up to five times faster in some cases now.

So a lot of file systems got some love.

where this one is not.

Now this is XFS, this is EFI, and this one's LVM.

I'm actually going to do a standard partition on this one with XFS because I'm not going to be doing any encryption.

And LVM is really nice if you're combining multiple drives and other things, but Frankly, for troubleshooting purposes, I like my installs to be pretty basic, and that's kind of my like.

If you don't like XFS, you could do ext4.

Very small differences between ext4 and XFS.

Too long didn't read the entire manual is XFS cannot be shrunk.

Ext4 can.
