i’ve instaled opensuse tumbleweed a bunch of times in the last few years, but i always used ext4 instead of btrfs because of previous bad experiences with it nearly a decade ago. every time, with no exceptions, the partition would crap itself into an irrecoverable state
this time around i figured that, since so many years had passed since i last tried btrfs, the filesystem would be in a more reliable state, so i decided to try it again on a new opensuse installation. already, right after installation, os-prober failed to setup opensuse’s entry in grub, but maybe that’s on me, since my main system is debian (turns out the problem was due to btrfs snapshots)
anyway, after a little more than a week, the partition turned read-only in the middle of a large compilation and then, after i rebooted, the partition died and was irrecoverable. could be due to some bad block or read failure from the hdd (it is supposedly brand new, but i guess it could be busted), but shit like this never happens to me on extfs, even if the hdd is literally dying. also, i have an ext4 and an ufs partition in the same hdd without any issues.
even if we suppose this is the hardware’s fault and not btrfs’s, should a file system be a little bit more resilient than that? at this rate, i feel like a cosmic ray could set off a btrfs corruption. i hear people claim all the time how mature btrfs is and that it no longer makes sense to create new ext4 partitions, but either i’m extremely unlucky with btrfs or the system is in fucking perpetual beta state and it will never change because it is just good enough for companies who can just, in the case of a partition failure, can just quickly switch the old hdd for a new one and copy the nightly backup over to it
in any case, i am never going to touch btrfs ever again and i’m always going to advise people to choose ext4 instead of btrfs
You’re right to give up on btrfs. It’s been so long in development and it just isn’t ready. Ext4 or ZFS are mature and excellent file systems. There’s no need for btrfs these days. It always has and always will disappoint.
Everyone singing the praises of it are the sysadmin equivalent of the software engineer yelling ‘it works on my machine’ when a user finds an issue.
I can’t comment on its server use cases or exotic workstation setups with RAID, NAS, etc. but I’ve been running Fedora on Btrfs for quite a few years now and I’ve had zero issues with it. Am I deliberately using all of its features like CoW, compression, snapshots…? No, but neither would your average Linux user who just wants something that works, like ext4.
I don’t miss ext4, Btrfs worked for me since day 1.
So, what you’re saying is, “it works on my machine”
And everyone else’s that uses Fedora?
Aren’t we all? Aren’t Ext4 and ZFS considered mature because so many people have said “it works on my machine”?
I agree this person’s experience may contrast to your own, but I don’t think the fact that something has worked well for some people, and perhaps not for yourself, is a reason to discount it entirely.
I’ve never heard anyone say ZFS broke, corrupted their data or failed in any way at all. With btrfs it’s a consistent complaint. And btrfs literally has modes of operation that are known to be broken. I could understand if it was a new file system, but it can almost drink in pubs.
