#ext4 — Public Fediverse posts

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.

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.

A friend got a protable projector (Elfin Flip) and realized it's running Linux.

So I downloaded the firmware (from 2022) and binwalked it:

```
...
633998388 0x25CA0C34 Linux EXT filesystem, blocks count: 477201, image size: 488653824, rev 1.0, ext2 filesystem data (mounted or unclean), UUID=4729639d-b5f2-5cc1-a120-9ac5f788f788, volume name "/"
...
```

mounted or unclean!

I'm sorry sir, but could you fsck your release before shipping?

New post on The Byte Architect:

**Filesystem Wars: Why Your Choice of Storage is Actually a Security Move**

This is not a “which filesystem should I use?” checklist. It is a walk through the ideas behind FFS, BFS, NTFS, ext4, ZFS, and APFS — and why storage design is never just about storage.

Crash consistency, journaling, soft updates, CoW, snapshots, encryption, space sharing: different filesystems solve different problems, and those choices shape reliability, usability, and security.

The real target, of course, is APFS.

Website backup crippled by 1.6MB Friends GIF that was replicated 246,173 times, breaking Linux's EXT4 filesystem limit — Jennifer Aniston's 'happy dance' animation ate up 377 gigabytes of data due to security policy

I've just moved a number of large files that I do not use often from an active partition to a backup partition.

What is odd is that the access speed to the active partition has increased significantly. Since that should not be possible, that must have to do with the manner in which the active partition is accessed by the Android operating system. Some research required.

Почему rollback на ext4 — боль, и как я решил это через rsync

Я не собирался делать этот проект. Просто однажды сломал систему — и понял, что rollback на ext4 не такая простая вещь, как кажется. В итоге собрал своё решение на rsync: быстрый и предсказуемый откат без смены файловой системы. Кода тут минимум — он на GitHub. В статье — про сам подход: проблему, попытки решения и итог. Вернуть систему

Kann ich bei einer fabrikneuen externen Festplatte, die eine Partition sda1 als Microsoft reserved Partition hat und eine sda2 als ntfs formatiert ist, die sda1 löschen und stattdessen die gesamte Platte mit einer Partition sda1 mit ext4 formatieren? Oder sollte ich die sda1 unangetastet lassen? Sie ist ohnehin nur 128MB groß?
Die USB-Festplatte soll als Datenpartition verwendet werden und auf Linuxsystemen genutzt werden.

#Partition #festplatte #ext4

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.

Haven't looked at this since I broke it. There really isn't any way to recover that #filesystem or files is there?

Most of my files were backed up one way or another. I'm sure I'm losing some things, but shouldn't be anything too important or critical, luckily.

I suppose this is an opportunity to redo the hard drive all together and maybe it's time I tried something other than #ext4. I don't think I would use #bcachefs tho, so I suppose that only leaves #zfs. Idk, need to do some reading.

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!

#Linux #Windows #Ubuntu #Ext4 #Btrfs #Upgrade

@mfuhrmann In theory kinda yes. It deepends on how you setup the tool. Number of snapshots ... But, under practical conditions not really.

I usually, just revert back to an earlier time point and things are fine. Anyways, you can also choose a snapshot during boot.

On #Debian based systems I use #timeshift (with #ext4) in a similar fashing.

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

#EXT4 is bullet proof and good.

#EXT4 In #Linux 7.0 Improves Write Performance For Concurrent Direct I/O Writes

https://www.phoronix.com/news/Linux-7.0-EXT4

I've recently finished a task set entrusted to me by a client. The task was executed 100% remotely with server farm(s) thousands of nautical miles away.

Skillset used are

• (remote) server VM management (XEN and ProxMox**)

• Linux client server experience

• VOIP (incl asterisk)

• specific migration skills varying from simple looking updates (which can break custom hard coded scripts & programs PHP code, C code, etc) to full server migrations to higher versions often spanning more than two versional steps in between

• filesystems in different Open Source OS where redundancy building of data is important

• bare metal skills

• BSD (limited yet good enough experience)

• Bare metal server placement

• Energy and heat distribution

• logic

• patience / patience / patience

• KISS

I get computing related tasks from this client for more than 30 years, which means that a solid basis of mutual trust has been build between us

I love having my client feeling extra great again after this task set was completed.

** Including proxmox LB code!

Take the time to analyse this post on Anna's Archive

They teach you in meticulous detail why they took the time to create mirror backups of this musical archive which is torrented in bulk at 300 TiB

#HDD #EXT4 #partitions #Linux #technology #InfoSec #passwords #Spotify #breach #300TB

https://annas-archive.li/blog/backing-up-spotify.html

@vermaden

It may look like I was joking but making such a backup is technically simple.

300TiB / 24TiB per HDD is 12.5 drives

300TiB / 16TiB is 18.75 drives

In reality it's more complex.
A 16TiB HDD is not 16TiB but 16TB lineair

Given a typical 4TB HDD I get just 3.64TiB in partitoned EXT4 HDD Space
That is 91% of the 4TB HDD

At 16TB that is 14.56 TiB {yes the loss is enormous and those hard drive companies are idiots because computer systems count in base² Binary not base10}

A 16TB drive is actually a 14.56 TiB Drive, it should be sold as 14.56 TiB not 16TB because that is misleading and false advertisement.

With these parameters we will need in reality 300 TiB / 14.56 TiB = 20.6
So we will need 21 drives for the task at 14.56 TiB. In the replication you will need twice the amount

This would become a JBOD just a bundle of drives, which is the easiest form to concatenate hard drive space to together.

A 4U JBOD enclosure can harbour a lot of drives. At the most you will need two.

Double the amount if you want a local backup of your main Spotify data.

Then you will need a 1U case for the computing System. A typical server motherboard, 1x AMD EPYC CPU, 512GB ram is more than sufficient.

You will need Fast Access to the Drive Array. 10GBit / sec in duplo should be enough. That means that your switches cables and network infrastructure will be expensive.

The high cost of AC power globally, can be a limiting factor when you have to power 42 hard drives provided that you are a Soho Network Builder, though.

That is the only factor you cannot calculate with constants

External disk with ext4 doesn’t auto-mount

Full post here. https://rene.seindal.dk/2025/12/08/external-disk-with-ext4-doesnt-auto-mount/

I have an external SSD in a NVME USB enclosure, with an EXT4 file-system. When I plug it in, it doesn't auto-mount, and haven't done so for a while.

Most other external disks do auto-mount.

I finally figured out why, and how to fix it.

For some reason and it wasn't installed on my Debian based MX Linux distro.

I've just installed sysstat, the package it comes in, and I have to Thank you for pointing me to the program

I remember that command from Linux and I've just checked online since I'm on the phone and found this hit

I didn't see that specific switch though

@rl_dane

Up to know I have not seen any USB thumb drive which can write as fast as it reads in practicality

The 64 to 256 GB thumb drives that I work with, write at about 6 to 8 Mbps when they are in sync mode

In the beginning the drive seems to lie and shows speeds that are close to the absolute speed of the USB 3 Connection. In reality is not really a lie because the Linux Operating System loves to cache it's file systems, especially if they're native, like ext4

However the file system warns you never to remove the thumb drive until it's actually done writing. If you use something like Midnight Commander it will show you that the writing speed drops all the way down to six to eight megabytes a second!

That happens on both modern systems and on Old obsolete systems with just USB 2

<Start/tip nobody asked for>
For those who want something close to Debian testing, #siduction (by default #KDE #Plasma6) might be worth a try. It is unstable (Codename: Sid), thus before testing. This means it is tested but, it is certainly not as stable as testing.
But here is the twist. Use it with #btrfs or #timeshift and #ext4 to have efficient tools for a rollback once it breaks (and it will break sporadically) and you should be good.

Is there any know-how about creating filesystems on top of RAID1? Both XFS and ext4 top out at 35 MB/s for me even though the block device below it is capable of 135 MB/s (yes, 4x difference!) This even with an absurdly large I/O request sizes like 512KB.

The disks are old-ish SATA drives with 512-byte sectors. XFS seem to use 512b sectors while ext4 picked 4k. They're connected via USB DAS, with dm-integrity on top of each disk, which are then combined into mdadm raid1, and encrypted with LUKS.

I confirmed with fio that the slowdown happens on the filesystem level, not LUKS or anywhere below it.

The only advice I found online is about alignment, but with 512KB requests it shouldn't be an issue because that's way larger than any of the block/sector sizes involved. I must be missing something, but what is it?

It was nice to wake up to not bootable desktop after hard reset due electric shortage of building.
Trying to restore my desktop main SSD. Still not sure if the issue with #ext4 or hard drive itself.
It complains about superblock, out of boundary partitions and some other scary things.
Trying to backup files (about 20h and 175Gb already extracted, not sure how much is there in total) with #testdisk.
Next step would be to try to backup root partition before I play around with it
