After being hosed by #btrfs on #linux 7.0.1, the #atomdrift postgresql master database is on #OmniOS & #ZFS

It's good to be back, even if I'm rusty in Solaris-based environments.

Is it just me, or does this look like an #ASCII #neocat?

I've been transitioning my home computers from #Manjaro to #Solus #Linux because I noticed that Solus puts out weekly updates and Manjaro moves far more slowly.

I thought I'd give #BTRFS a try instead of #ext4 since on Manjaro, BTRFS has become the default and it worked well.

For some reason, it really didn't play well with Solus. I couldn't log into #Element at all and I had problems running #Cyberpunk2077 with #Heroic.

I reinstalled with ext4 and those problems went away.

I did, for some reason, have trouble installing Heroic from the repo and had to use #Flatpak instead, but I'm getting more comfortable with those. I let the computer redownload CPB2077 overnight and tried to run it this morning. It even remembered my progress, which was a fear.

Ubuntu 26.04 + Btrfs: missing @ subvolumes #systeminstallation #btrfs #timeshift #2604

https://askubuntu.com/q/1566142/612

The move to #Trisquel 12 seems to be a complete success! Took the opportunity to do a complete wipe and reinstall to transition all drives to #btrfs. The system's running flawlessly, and BorgBackup is currently restoring all my documents to the freshly formatted drives. #GNU #Linux #FreeSoftware #SoftwareFreedom

Man is it annoying when a filesystem doesn't implement the "-o uid=,gid=" options.

Btrfs for example:
1) mount it
2) create a btrfs snapshot
3) sudo chown -R uid:gid /mount/path/
4) wait for multiple hours for it to apply
5) do the thing you wanted to do from the beginning (like e.g. browse a disk of an offline system, test a backup, ...)
6) revert the snapshot
7) wait for it to revert
8) unmount

BTRFS? LMAO. I use ext4. I don't like dealing with any other fs. Stability is what I want when it comes to the data I put into storage. It's the bedrock to everything I do in my systems so I want a rock stable bedrock. Fuck all the fancy shit. Ext4 on linux all the way

Snapper? Tf is dat? I just make a compressed dd image of my root drive. I don't wanna waste time twiddling with rsync or something UNLESS NECESSARY. I don't backup my system that frequent though.

Trisquel 12 upgrade time. Since I normally do a full reformat and reinstall for major OS upgrades anyway I'm using this as the perfect excuse to migrate my root partitions from ext4 to btrfs. Slowly rolling this out across my fleet of machines so it'll take a while. Anyone else making the switch? #Trisquel #GNU #Linux #btrfs #FreeSoftware #SoftwareFreedom

🎉🎊 Breaking news, folks! Healthchecks.io has bravely decided to self-host their object storage like it's some kind of revolutionary act in 2026. 🚀 Good thing, too—in a world where everyone wants to hand over their data to the cloud, it's heartwarming to see someone reinstalling their hipster credentials with a #Btrfs #filesystem. 🙄✨

Implementation of snapshots in USBridge.

I designed the system as a standalone mechanism, isolated from the host OS. The key priorities are determinism and data protection.
No drivers or agents. The host has no physical ability to delete or modify snapshots—this provides protection against OS compromise or encryption tools.

I use the Copy-on-Write mechanism. Snapshots are created instantly, without duplicating immutable data. Immediately after creation, the snapshot is sealed as a read-only subvolume.
I have disabled the automatic deletion of old blocks. If space runs low, archive mode is used so that the history isn’t erased by the algorithm.
Data can be read on any Linux system (native Btrfs).

New article: Btrfs 🌳

The Linux filesystem that never overwrites data. Every write goes to a new location.

Snapshots, RAID, per-block checksums with auto-repair on RAID, atomic transactions, all built into the filesystem.

Case study: recovery of a corrupted 12 TB multi-device pool

zstd 15 compressed btrfs on-top of dm_crypt/Luks2 on-top of dm_raid 5 on 4 slow 2.5" HDDs may be quite great for storage and ok-ish for accessing individual files.

But man is it slow in copying 3TB of files off of this thing onto another zstd 9 compressed btrfs on-top of dm_crypt/Luks2 on-top of dm_raid 5 on 4 also slow 3.5" HDDs.

Verdammt, Ich habe gerade realisiert, dass ich gestern als ich das #Linux installiert habe, die Partitionen als #EXT4 formatiert habe. Ich wollte doch ursprünglich #BTRFS nehmen.
Na gut, kein Beinbruch. Kann ich jetzt auch nicht mehr ändern.

Noch schnell einen Scrub durchführen. Dank KI traue ich mich heute an Themen, die früher viel zu kompliziert für mich als Laien waren.

Today my work machine graduated from Windows 11 to Ubuntu 24.04. The hardware hasn’t changed. I would have preferred Kubuntu. They gave me ext4 instead of btrfs. But my wishes there are nice-to-haves. What they gave me is a huge step!

Linus Torvalds announces Linux 7.0-rc1

https://fed.brid.gy/r/https://nerds.xyz/2026/02/linux-7-0-rc1/

New blog post!

Using the Arch Linux installation image and working my way through the excellent installation guide, I show the choices I make to create an encrypted, minimal Linux system with “just enough” to provide a solid foundation to build upon further: whether that be setting up a desktop, laptop, or server:

https://www.dwarmstrong.org/archlinux-install/

#ArchLinux #Linux #LUKS #BTRFS

@mistersheep even network traffic should be lower with #borgBackup than plain #btrfs send. If haven't worked with btrfs send yet, but I guess it's faster than borg if you leave network speed out of the equation.

Now I'm thinking about a new strategy:

- stop service
- make #btrfs snapshot (seconds at max)
- restart service
- run #borgBackup from snapshot, but via #bubbleWrap so it sees it as the original path and inodes for consistency&performance!
- run as many borg backups as desired to any remote, even in parallel, as the service is running again

Thoughs?

#nixos

@sbeak Unless there is a specific use case to use #BTRFS use #EXT4.

#EXT4 is bullet proof and good.

Support for bounce buffering of DirectIO for stable pages was merged for #Linux 7.0 via @axboe

https://git.kernel.org/torvalds/c/4adc13ed7c281c16152a700e47b65d17de07321a

""This series tries to address the problem that under I/O pages can be modified during direct I/O, even when the device or file system require stable pages during I/O to calculate checksums, parity or data operations. It does so by adding block layer helpers to bounce buffer an iov_iter into a bio, then wires that up in iomap and ultimately XFS.

The reason that the file system even needs to know about it, is because reads need a user context to copy the data back, and the infrastructure to defer ioends to a workqueue currently sits in #XFS. I'm going to look into moving that into ioend and enabling it for other file systems. Additionally #btrfs already has it's own infrastructure for this, and actually an urgent need to bounce buffer, so this should be useful there and could be wire up easily. In fact the idea comes from patches by Qu that did this in btrfs. […]""
