Nachdem ZFS (zfsutils-linux) unter Armbian immer noch nicht installierbar ist wegen nicht auflösbarer Paketkonflikte und ich relativ schnell eine funktionierende Lösung brauche, habe ich gestern mal mit etwas Aufwand auf BTRFS umgestellt und sehe mir das nun mal an.
Ist eh überfällig, mich damit mal genauer auseinandersetzen.
filesystem defenders act like it's natural for a computer to have a filesystem. meanwhile filesystem implementors are hard at work convincing me that not only is a filesystem a bad idea, it's also virtually impossible to implement any nontrivial optimizations in one without catastrophic data loss bugs
What do you use to back up local files from Linux to external hard drive?
I have been using rsnapshot, but maybe there are better solutions out there?
Does anyone have an experience with btrfs and snapshots? Do you trust it?
And I know where to begin with #SUSE. SUSE's documentation is excellent and generally publicly available. Their paid support is excellent. SLEMicro is excellent for hosting Kubernetes and other workloads. And SUSE supports #btrfs out of box!

I searched Google for that "corrupted node" message and found that it had happened to someone else recently too: Linus Torvalds, just after merging a #Btrfs pull request. (This was not the first time Linus and I had hit the same bug. We both have the same CPU in our desktops. […]"
@sebsauvage Hopla ! Je m'appuie pas mal sur ton wiki pour mon usage perso de #btrfs. J'ai eu un pb aujourd'hui d'espace disque que j'ai résolu par un "btrfs balance". En fouillant un peu le grand internet pour creuser la question, je sui tombé sur ça : https://github.com/kdave/btrfsmaintenance
Tu connaitrais-tu ?
🐧 #Linux#btrfs
Le répertoire ".steam" sur ma machine perso contient 196 Go de données.
Mais grâce à la compression et déduplication, ça n'occupe que 162 Go sur le disque.
34 Go gagnés sans se fatiguer.
btrfs c'est la vie ! \o/
Combined with the packages apk-snap 📸 and #mangr0ve 🌴 available on #AlpineLinux's edge channel testing repo, you get automatic snapshots of / when apk installs, removes or upgrades packages; as well as a nice tool for rolling back to a previous snapshot if something goes wrong 😄
The recent release of bcachefs made me wonder about rolling release distributions, updates and filesystem snapshots.
I'm running #Gentoo, and while it happens very, very rarely, world updates sometimes break the system. So, having a filesystem with snapshot support for the root partition might be worthwhile...
I've just converted my root partition to #btrfs, therefore.
I'm not going to try bcachefs on my main PC yet, and btrfs has been running fine on my phone and laptop for years.
Now we have a basic subvol layout by default in #PostmarketOS, and when #sourcehut comes online again, I'll send a new patch with more comprehensive subvolume handling 🌠
Had a #btrfs corruption issue on my laptop preventing the access/deletion of a directory under the #snap data directory of the #Ferdium snap which was also preventing the upgrade and removal of the snap. Decided to #YOLO it and ran 'btrfs check --repair' from a live media session and it fixed the corruption without any unexpected side effects! 😌 🎉
I bought a larger SSD to move my laptop to #Fedora#Silverblue (might later decide to use one of the derivatives, once it's just a "rebase and try it out" operation).
Can I choose XXHASH while installing Silverblue? I'd prefer a still fast, but more collision-resistant hash than CRC32C.
If I do btrfs, then I have to decide how to do space management. I'd kind of like at least to separate space utilization for / and /home (well, /var/home on Silverblue). Maybe /var/containers too.
Is the norm to have one big filesystem with subvolumes here, or to create multiple btrfs filesystems on separate devices?
Maybe I'm being a control freak and I should just make one big filesystem for / and lean into subvolumes for snapshots?
For VMs, are qcow2 files on btrfs actually a good way to go? This is a laptop, so VMs are not normally running, I just need to spin them up occasionally.
System keeps freezing **UPDATE: It was Android Studio**
I have been having a strange issue since a couple of days ago. Every so often, the following happens:...
