Phoronix: F2FS Data Compression Using LZO/LZ4 + Selective File Extension Handling To Land In 2020

F2FS is the latest Linux file-system gaining transparent data compression support for saving on-disk space. With F2FS there are two compression algorithms supported so far plus the support of making the data compression opt-in per file or applying the compression to select file extensions(s)...

It appears that F2FS has both an fsck tool and a defrag tool (both from the f2fs-tools package).

Have we reached the point where F2FS is safe for root FS use on PCs with SSDs? Or did we reach that point a while ago and I just didn't notice?

I remember trying it on a late 4.x kernel and being surprised that fsck on the rootfs failed on boot (it was a known issue with fsck-tools-1.12 apparently).

root FS use on PCs with SSDs

SSDs don't really care that much about F2FS, it was designed for eMMC and other devices with weak storage controllers.

I've been using it as the root FS on a raspberry pi 3 (SD card, not SSD) since 4.19 and haven't had any problems at all other than fsck on boot being slow (1-2 minutes) if the pi suddenly loses power instead of properly shutting down.

I've also been using F2FS on the Raspberry Pi for a few years now and have never had a problem with it.

Using F2FS on two disks on my Gentoo system. So far so good!



Also, F2FS developers need to implement a function like LVM* to integrated another disk to root disk AFTER the system has installed.

Why not just use LVM for that?

LVM adds much overhead and this kills one of the purposes of F2FS.

It's weird how each FS needs to implement this instead of having some generic layer doing it for all.

Using f2fs for root with my SSD for 3-4 years. All good.
