Phoronix: Btrfs / EXT4 / F2FS / XFS Benchmarks On The Linux 4.12 Kernel Given the big changes of the Linux 4.12 kernel and a lot of that being block/file Dec 17, 2015 · Even take a look at these benchmarks to prove that F2FS performance is better. We all know how a little bit slow the live USB installations can be. So if we can install Linux on an F2FS filesystem, it will make it a bit faster. Also, as a plus point, F2FS increases the life of your pen drive or SSD. Neat! I'm curious here - > F2FS is intended for raw flash access, on which platform(s) grub has > access to such devices? I just followed the commit convention in grub.git. Anyway I'll add some description in v2. Phoronix: Btrfs / EXT4 / F2FS / XFS Benchmarks On The Linux 4.12 Kernel Given the big changes of the Linux 4.12 kernel and a lot of that being block/file Warning: If using GRUB your freshly installed system might not boot after reboot.As GRUB doesn't support F2FS it isn't able to extract the UUID (which is persistent across reboots) of your drive so it uses classic /dev/sdXx names instead (which are not guaranteed to be persistent across reboots). Fixup initramfs and grub This adds f2fs modules to initramfs so when system boots it can see the f2fs root. It then installs grub to the target drive. nano /etc/fstab echo "f2fs" >> /etc/initramfs-tools/modules update-initramfs -u grub-install /dev/sda update-grub Dec 17, 2015 · Even take a look at these benchmarks to prove that F2FS performance is better.

Also, as a plus point, F2FS increases the life of your pen drive or SSD. Neat! For new installations, GRUB 2 and Funtoo's boot-update tool should be used as a boot loader. GRUB supports both GPT/GUID and legacy MBR partitioning schemes. To use this recommended boot method, first emerge boot-update. This will also cause grub-2 to be merged, since it is a dependency of boot-update. Jul 12, 2013 · I would tend to think using the latest (or near to it) kernel would be better for f2fs support as it was accepted in the main tree in k3.8. The only reason I wanted to backport it was for better driver suppot in 3.4 for some older nvidia chips, which a lot of my users have. Warning: If using GRUB your freshly installed system might not boot after reboot.As GRUB doesn't support F2FS it isn't able to extract the UUID (which is persistent across reboots) of your drive so it uses classic /dev/sdXx names instead (which are not guaranteed to be persistent across reboots). F2FS divides the whole volume into a number of segments, each of which is fixed at 2 MB. A section is composed of consecutive segments, and a zone consists of a set of sections. By default, section and zone sizes are set to the same size, but users can easily modify the size with mkfs . When researching my article from last month, An introduction to the Linux boot and startup process, I became interested in learning more about GRUB2. This article provides a quick introduction to configuring GRUB2, which I will mostly refer to as GRUB for simplicity. In set_node_addr, we try to lookup cached nat entry of inode and then set flag in it. But previously in this function, we have already grabbed nat entry with current node id, if the node id is the same as the one of inode, we do not need to lookup it in cache again. File systems F2FS (Flash-Friendly File System) is a file system intended for NAND-based flash memory equipped with Flash Translation Layer. Unlike JFFS or UBIFS it relies on FTL to handle write distribution. It is supported from kernel 3.8 onwards. Jan 20, 2014 · F2FS has had a lot of improvement in the latest kernels, performing better than EXT4 in some cases. So I'm wondering if there's a way to install Linux Mint on a F2FS. I understand Gparted does support f2fs now, but grub doesn't (and that could be solved by having a /boot partition with ext4)... Hi , I made the mistake during installation and I am using f2fs as root and on every kernel update I have to: change the line root=/dev/nvme1n1p1 to root=UUID=xxx-xxx-xxxx-xxx-xxx otherwise I will end with a non bootable system. I have to delete manually the previous modified grub Kernel entries because the modified entries are not updated. I am using 3x Kernel versions and Imagine having to ...

According to The Arch Wiki ( [1] , [2] ) it should be possible to use F2FS for root, provided that GRUB is installed to a separate partition with another filesystem which it supports.

I understand Gparted does support f2fs now, but grub doesn't (and that could be solved by having a /boot partition with ext4)... Extensive, detailed tutorial about how to setup and configure GRUB 2 (version 2, the next generation) bootloader with multiple operating systems, including GRUB legacy and GRUB 2 mix, dual-boot and triple-boot real-life testcases, upgrades, customization, troubleshooting, backup, rescue and recovery, BIOS and EFI/UEFI systems, and more So the grub EFI image can load configuration, kernel images and initrd from a /boot that is formatted in F2FS (the upstream grub supports the filesystem since 2.04). Now that the kernel is loading it must be able to mount the rootfs. Is F2FS a fully-fledged filesystem - can I use it on a desktop machine? Hopefully I can try out F2FS once my new SSD arrives - without deleting my current OS (Ubuntu 13.04) or creating a new partition.I'm concerned about the inherent lack of feature - will Samsung be supporting/linux kernel be supporting this to the same level as ext4?

Apr 11, 2018 · F2FS lead developer Jaegeuk Kim authored this file-system support addition for GRUB. Previously the work was carried by OpenMandriva among other distributions while now is upstream in GRUB Git for allowing /boot to be on a F2FS-formatted partition. The code is in Git ahead of GRUB 2.04 expected later this year. UUID="d8e59df1-b8c4-4862-9017-1f66e6e6a7dc" / f2fs defaults 0 1. Next, update GRUB information. It might be useful to repeat this step once the system reboots into the installed system. # update-grub2. Now we are ready to reboot into the installed system that now uses an F2FS file system. Post-Installation Steps God bless the folks over at Manjaro, the distro I came from before I came here. They've got a special version of GRUB! It is '2.03' (at least what it says on the package), they've got F2FS root support - I am using it now & it works pretty great, I had to use the pkg.tar.xz binary because I was running into issues trying to get it to compile if I recall correctly. This seem to be perfectly normal, "grub-probe" is not supposed to detect F2FS filesystems (my old grub.cfg works perfectly fine though, it doesn't even reference the F2FS filesystem, just the /boot partition which is ext4, so I doubt it is really needed here). This is the commit responsible of the problem, which introduces 10_archlinux: GRUB (GRand Unified Bootloader) is a multi-boot loader.It is derived from PUPA which was a research project to develop the replacement of what is now known as GRUB Legacy. I also running artix on f2fs, but installed it via chroot and booted directly via efistub, if you installed artix using calamares installer, it will automatically install grub bootloader, in that case, you might need to chroot and manually edit grub.cfg, just follow this Arch wiki manual, grub-install: error: unknown filesystem. According to The Arch Wiki ( [1] , [2] ) it should be possible to use F2FS for root, provided that GRUB is installed to a separate partition with another filesystem which it supports. Mar 15, 2016 · I re-installed Grub for good measure: grub-install /dev/sdX && update-grub2; Now, I had to manually edit /boot/grub/grub.cfg to make the changes I specified above — replacing hd1,msdos1 with hd0,msdos1, and setting my F2FS partition as rw Jul 12, 2013 · I would tend to think using the latest (or near to it) kernel would be better for f2fs support as it was accepted in the main tree in k3.8.
