Infinito.Nexus 12.0: From a Single Server to a Scalable Sovereign Cloud
Infinito.Nexus 12.0 is one of the most significant releases in the project’s history. Until now, Infinito.Nexus focused primarily on automating complete open-source environments on a single Docker Compose host. Version 12.0 introduces Docker Swarm as a second deployment mode, enabling applications to run across multiple servers, scale horizontally and recover from node failures. This release combines capabilities that are rarely delivered by one automation platform: More than 75 automatically deployable open-source applications One Single Sign-On experience backed by a unified user database Horizontal scaling across multiple cloud servers Automated backup and continuously tested disaster recovery Support across Debian, Arch Linux and RHEL-family distributions Filesystem-independent operation across ext4, btrfs and ZFS Together, these changes transform Infinito.Nexus from an application installer into a comprehensive foundation for scalable, sovereign cloud infrastructure.

Uh oh, I should have used
findmnt --verify --verboseto validate fstab, notmount -a. Well, I did learn something in the process.Using
debugfsto modify files directly on the filesystem, without mounting it at all. Withdebugfs, the read-only (ro) flag doesn’t apply. -

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.

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.

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. -

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!

@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.

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!

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