KDE: KIO Snapshot bringt Btrfs-Snapshots in den Dateimanager
https://linuxnews.de/kde-kio-snapshot-bringt-btrfs-snapshots-in-den-dateimanager/ #kde #btrfs #snapshots #linux #linuxnews -
When I started using Linux some 30 years ago, I used ext2 as its filesystem. That became ext3 and then ext4, and LVM came along. All the tools you need for basically everything you would ever need to do with filesystems. ReiserFS seemed promising, but... well... we all know the sad end of that.
I feel it's time to move to something more modern, just like the creator of ext2, ext3 and ext4 has done. There are a few candidates, but for me it boils down to ZFS or BTRFS.
I have a bit of experience with zfs, and once you master the basics, it's pretty powerful. But it's also hungry in RAM, and it's at its best at high loads.

I feel it's time to move to something more modern, just like the creator of ext2, ext3 and ext4 has done. There are a few candidates, but for me it boils down to ZFS or BTRFS.
I have a bit of experience with zfs, and once you master the basics, it's pretty powerful. But it's also hungry in RAM, and it's at its best at high loads.
ZFS vs BTRFS
Then there's btrfs, which seems to be really stable now. Does pretty much what zfs does, using a lot less RAM, but it only runs on Linux. That's what I use, but it would be nice to know that I can mount an fs on a different OS if I need to, say OpenBSD.
It's also not optimized for the high loads that zfs likes, which makes it much more appropriate for my small private environments. Points for btrfs.
Send-receive looks really nice. I haven't used it myself yet, but at work it's used a lot on zfs. Writable snapshots is a really nice thing to have, I can imagine using that for cloning dev-environments and running them on the actual original snapshot. That's btrfs-only, so more points for that.
A big booh for zfs is that it's not open enough to be in Debian, so you'll have to compile the kernel-modules every time you update your kernel. That takes more than enough time for me to get irritated.
So, guess it's time to get myself some experience with btrfs...

🛠️ Linux 7.3 aduce optimizări majore pentru sistemul de fișiere Btrfs: Direct I/O dublat, performanțe mai bune pe HDD și dezactivarea Free Space v1!În cadrul ferestrei de dezvoltare pentru Linux 7.3, echipa de menținere a sistemului de fișiere Btrfs a trimis un pull request consistent ce conține o serie de optimizări de performanță, curățări ale codului legacy și îmbunătățiri de scalabilitate. ✨ Principalele noutăți și optimizări Btrfs din Linux 7.3:⚡ Direct I/O masiv accelerat (apropiat de limita teoretică):• A fost eliminat un blocaj important ce afecta operațiunile Direct I/O (DIO). Prin trecerea la bufferul de tip iomap bounce și evitarea căderilor inutile în modul buffered I/O, performanța Direct I/O pe stocări rapide (cum ar fi SSD-urile PCIe Gen5 NVMe) a crescut de la ~50% până la ~95% din viteza maximă teoretică.💿 Performanță îmbunătățită pe HDD-uri (non-SSD) & I/O paralel:• Include optimizări la nivel de readahead și gestionare a cererilor I/O pentru mediile de stocare mecanică tradiționale, reducând latența la accesarea fișierelor fragmentate sau la procesarea sarcinilor paralele mari.🧹 Dezactivarea versiunii vechi de spațiu liber (Free Space v1):• Formatul legacy Free Space v1 este acum dezactivat implicit în favoarea arhitecturii moderne Free Space v2 (free-space-tree). Această schimbare reduce complexitatea codului și elimină problemele istorice de performanță la montarea sau scrierea pe partiții cu capacități mari.📊 Alocare mai eficientă a memoriei și gestionare mai bună a extinderilor (extents):• Optimizările aduse structurilor interne de date (precum arborele de stocare a hărților de memorie) reduc consumul de RAM și accelerează operațiunile uzuale create pe volum, precum crearea și ștergerea rapidă a fișierelor mici. O versiune extrem de importantă pentru utilizatorii de Btrfs, care transformă acest sistem de fișiere într-o opțiune și mai competitivă pentru mașini virtuale, baze de date și medii de stocare de înaltă performanță! 🚀#Linux #LinuxKernel #Btrfs #Linux73 #Phoronix #Storage #SysAdmin #TechNews #OpenSource #FOSS

BTRFS gets a substantial performance improvement in Linux 7.3
A substantial performance improvement has been made to the BTRFS file system as of Linux version 7.3, which is still under development until now. A pull request has recently been submitted so that BTRFS finally uses the IOmap bounce buffer for direct input and output instead of falling back to the buffered I/O.
BTRFS also utilizes the local LRU list instead of XArray that tracks inhibited extent buffers, and removes one unnecessary “jiffy” delay in the non-SSD mode with multiple logging tasks.
As a result, the performance gain has become 3x to 5x the speed of BTRFS in Linux 7.2. This means that this file system has become faster than before, and many improvements to the file system were made.
For more information, read more about it here.

The #Ubuntu installer for #BTRFS defaults to `discard` on 26.04 LTS.
This completely destroys all interactivity on these systems when performing many package transactions (e.g. by updating) because it is `discard=sync` implicitely.
Remove the `discard`-option in /etc/fstab, or specify `discard=async`. -
I've got an nvme SSD in a usb-c enclosure that's going read-only in the middle of rsyncing to it. btrfs on luks.
I suspect the SSD may be failing early, but I can't verify it. Nothing I've tried yet with SMART tooling shows any problems, and btrfs check doesn't reveal any problems either.
Anyone got a good process for making an SSD clearly demonstrate that it's failing? Must be possible to do from linux, and ideally would be acceptable proof of failure by HP for RMA purposes.
I don't need the data on the drive, I can reformat and repartition as needed to torture it into failing or whatever

🔍 Clarificare privind numărul de versiune al kernelului Linux
Această știre sau titlu pare să fie o confuzie de numerotare sau un scenariu ipotetic. În prezent, dezvoltarea kernelului Linux se află în seria 6.x (versiunile recente din 2026 fiind în gama Linux 6.13 - 6.15+). Versiunea 7.2 nu a fost încă lansată oficial de către Linus Torvalds.
Cu toate acestea, dacă analizăm îmbunătățirile menționate (Btrfs, Scheduler și Networking), acestea reprezintă piloni principali de dezvoltare activă în kernelul Linux:
✨ Arii majore de optimizare în versiunile recente de kernel:
🗄️ Sistemul de fișiere Btrfs:
• Implementarea de noi optimizări pentru gestionarea spațiului Liber (free space tree), reducerea latențelor la operațiunile fsync, îmbunătățirea performanței în configurații RAID și citiri paralele mai rapide pe unități NVMe/SSD.⚡ Scheduler-ul de procese (EEVDF / Scheduler Updates):
• Rafinarea scheduler-ului EEVDF (Earliest Eligible Virtual Deadline First) pentru o mai bună alocare a timpului de procesor între sarcinile interactive (cum ar fi jocurile sau interfața grafică) și procesele de fundal (background jobs).
• Optimizări speciale pentru procesoarele moderne cu arhitectură hibridă (core-uri P și E).🌐 Stiva de Rețea (Networking Enhancements):
• Optimizări la nivelul stivei TCP/IP pentru reducerea latenței la viteze de transfer ridicate (100GbE+).
• Îmbunătățiri de securitate și viteze crescute pentru modulele eBPF și conexiunile VPN native WireGuard.📌 Notă: Dacă articolul respectiv face referire la un release recent (din seria 6.x), este recomandat să verificați numărul exact al versiunii în fișierele oficiale de release de pe kernel.org.

Created a BTRFS snapshot of /, upgraded anyway #yolo, rebooted, and ZFS is working fine. 🤷
I had to turn off my swapfile to make the snapshot, and now it won't turn back on. I have no idea what I'm doing.

Ok, I think I'm getting in over my head on this computer problem, any help much appreciated! (Linux/Opensuse TW/KDE/btrfs)
Symptom: Everything that tries to save something to my home partition (configurations, sessions, kwallet, etc.) says that I have no space left, and thus won't work. Some programs won't even load (Vivaldi, Steam). Every file manager I have tells me that I do have space left.
History: Before this happened I had tried updating a game in Steam thinking that it would warn me if there wasn't enough room on the disk to do so (silly me). Then the whole desktop crashed and I had to restart.
Tried: 1) deleting several GB of files. I can now download files to /home, but all the other stuff still won't work.
2) running fsck from bootable flash drive. Mostly didn't do anything. Finally got it to tell me to use btrfs check instead (I am using btrfs).
3) I did that and it told me that there were errors. The only things that looked like errors was in "Checking free space tree" where it said "Space key logical (number) length (number) has no corresponding block group" twice with different numbers.
4) Not being terribly familiar with btrfs yet, I read the fine manual for btrfs check. There were lots of warnings about not trying to repair a btrfs without experienced help, else risking your volumes. So here I am. -
