Just a simple question : Which file system do you recommend for Linux? Ext4…?
EDIT : Thanks to everyone who commented, I think I will try btrfs on my root partition and keep ext4 for my home directory 😃
If you’re just doing a vanilla Linux install, ext4 is the way to go.
Upvoted. Not everyone wants to rely on backups and restore broken system every month like on BTRFS
Good that you mentioned that. Reminded me that I have an Arch Linux install here where I forgot that I did choose BTRFS during installation. Within maybe a month I noticed FS errors. Looked scary. Nervously searching for documentation was even more scary :
https://wiki.archlinux.org/title/btrfs#btrfs_check ->
This article or section is out of date.(Discuss in Talk:Btrfs) Warning: Since Btrfs is under heavy development, especially the btrfs check command, it is highly recommended to create a backup and consult btrfs-check(8) before executing btrfs check with the --repair switch.What is this? My beloved Arch Wiki is not 100% perfect!
Then found this :
WARNING: Using ‘–repair’ can further damage a filesystem instead of helping if it can’t fix your particular issue.
Do not use --repair unless you are advised to do so by a developer or an experienced user, and then only after having accepted that no fsck successfully repair all types of filesystem corruption. E.g. some other software or hardware bugs can fatally damage a volume.
I figure this explains the popularity of BTRFS snapshot configurations. Luckily I had some backups :)
Filesystem snapshots won’t help, if the filesystem itself corrupts. But I’ve been using BTRFS for 6 years now and haven’t had a file system corruption, so mileage may obviously vary.
I don’t know what’s the brand neW meta pick, but at least BTRFS over Ext4. BTRFS is just more stable and less corruptable than Ext4. Heck, fedora changed to it as default
To be fair, Fedora switching to something as default isn’t a good sign that you should start using it. I do agree, though, btrfs has come far enough to be a default choice for most people.
What did fedora adopt that wasn’t a good choice in hindsight?
PulseAudio?
So i normally go with ext4, however windows can’t really access ext4 drives so you’d need to find a file system that both support if you want to access the drive/partition from windows. My drive with all the games is ntfs for example which works in Windows and Linux. (At least for normal storage, idk if you can boot linux from it although i wouldn’t see why not)
Wsl2 lets windows do ext4
There’s also an open source BTRFS driver for Windows.
Ext4 is, afaik, the fastest as it’s the most understood
Btrfs has compression and you can make snapshots to roll back to if something goes wrong (not necessary on immutable distros or NixOS tho)
There are many other options, but I’ve only ever had a need for those two
btrfs snapshots are still useful on immutable distros to recover accidentally deleted data.
True, but with files, you really benefit from the speed that ext4 provides
BTRFS &/OR EXT4
I personally use ext4 everywhere but it is recommend to have BTRFS for your OS partition if you take snapshots often.
Btrfs or XFS.
No idea why people are into EXT4. XFS is more performant by far.
No love for bcachefs?
Uff, somehow missed your post. See mine. That’s the FS I’m hoping to use next. I’m waiting for it to support swapfile, or alternatively read from official sources they won’t ever support it, :). But yes, that’s the one I’m looking forward to use.
I’ve been very happy with btrfs. Ext4 is basically rock solid, so you can’t really go wrong with it, but btrfs has some nice features that ext4 doesn’t have, like snapshots. And it’s fast. I have an extremely cheap SSD that’s too slow to run anything with ext4, but actually usable with btrfs.
btrfs is objectively slower than ext4. It is CoW and maintains more complex metadata.
Only situations it wins is when lots of copies are made at once. Not a super common workflow compared to writes imo.
As someone who ran BTRFS for years, I’m personally switching back to EXT4. Yes, the compression and other features are nice, but when things go wrong and you have to do a recovery, it’s not worth the complexity
I prefer ext4 on HDD and f2fs on flash devices.
Also taking f2fs for a spin.
As far as I have experienced (I didn’t measure this): don’t use that partition for container layers. It might just be my system, but f2fs has slowed my container engine down a bit.
I excactly doing this. I run coreOS with f2fs and it runs really fast. No issues so far.
Removed by mod
For interoperability, yes. But with flash devices I mean ssd and nvme.
How about bcachefs. I’m waiting for it to support swapfiles, which seems to be in the TODO list, but so far doesn’t work. If you use swap partition[s], or prefer not to have swap at all (I never fell for this, and besides swap is required for hibernation if that’s a thing for you), then bcachefs is ready for you. It’s already part of linux since 6.7, and on Artix, current linux is 6.8.9…
To me is the FS to use. I’m still on luks + ext4 (no LVM) and do entire home backups with plain rsync to an external device. I’d have to learn new stuff, since ext4 is really basic and easy to configure if in need, but I think bcachefs is worth it, and as mentioned, just waiting for it to support swapfiles, :)
Thank you for sharing this. I didn’t know this FS yet. It seems new and have some nice goals. I always have a grudge against zfs/btrfs because of the resource usage/performance.
I’ll keep an eye on this. I’d love to find some benchmarks.
I prefer using ext4 for stability. But if stability doesn’t matter to you, you should use BTRFS.
btrfs every day of the week. The only scenario where I’d even consider something else is for databases that would suffer from CoW.
I’ve been running it on my home server since 2010. The same array has grown from 6x2TB to 6x4TB, one disk at a time as they’ve failed. Currently sitting at 2x18TB+1x4TB. No data loss even though many drives have failed.
Ext4 for most home users, because it’s simple and intuitive. Btrfs for anyone who has important data or wants to geek out about file systems. It’s got some really cool features, but to actually use most of them you’ll have to do some learning.
