🎨 #Macs and mysteries! Dive into a riveting tale of #inodes, where file systems get their very own numerical identity crisis. 🤓 Because nothing screams excitement like the riveting history of index nodes—mystical structures that only the bravest can pretend to care about! 🧙‍♂️✨

Explainer: inodes and inode numbers

How APFS is the first Mac native file system to have true inodes and inode numbers. What they are, and how you can use them in volume groups and different types of file link.

🌗 磁碟只是一堆位元
➤ 揭開檔案儲存的神祕面紗
✤ https://www.cyberdemon.org/2023/07/19/bunch-of-bits.html
這篇文章深入探討了檔案在磁碟上的儲存方式。作者從「磁碟只是一堆位元」這個概念出發，一步步展示如何使用工具（如 `stat` 和 `debugfs`）來解析檔案的 inode，並最終找到 inode 在磁碟上的實際位置以及其原始位元資料。文章不僅解釋了 inode 的作用，也說明瞭檔案系統如何將這些位元轉化為我們熟悉的檔案和目錄結構。
+ 這篇文章真的很有趣！我一直很好奇檔案在硬碟裡到底是什麼樣子，這篇文章用很清楚的方式解釋了這個問題，而且還能實際操作，非常棒。
+ 雖然有些技術細節有點難懂，但作者的思路很清晰，一步步引導你瞭解檔案系統的運作原理，讓人對電腦的理解更深入了。

A disk is a bunch of bits

We've heard that a disk is a "bunch of bits", so let's get dirty and personal with those bits.

You can rename or move a file that a program is currently using — and it’ll still work.
#Linux tracks file #inodes, not filenames. Programs access files by #inode, so renaming doesn’t affect the process unless it reopens the file.

pineWintermute broke down again.
Broken #inodes. Of course I was too lazy to prepare my own #microSD card with a #ManjaroLive for #ARM system.
Be patient my dear until this evening in the nearest #hackerspace Ruum42.ch.

Imagine a vast library where books are meticulously organized, each with its own unique identifier and location. This is the essence of a Linux filesystem - a sophisticated system that manages and organizes data on your computer's storage devices.

The following article is a nice introduction to understand #Linux #Filesystems: #inodes, block sizes, and data structures:

#security audit time for #snac.

This time is for #inodes space.

- Having an Mastodon API enabled in your #snac (which is default) also gives an chance to attacker for filling up your inodes by creating bunch of "Mastodon API apps" in your instance.
- The more external posts or interactions that you got, The more inodes spaces being taken.

Well, Both of these things could be prevented, However it is still not easy for the second one for some reasons.

Alright. Have a good day everyone, Here's #Bocchi meme for you.

Für alle #Admin unter euch ein interessantes #Video (https://www.yewtu.be/watch?v=EOa5zoDl6gY) auf dem Kanal #RaspberryPiCloud zum Thema voller #Speicherplatz unter #Linux.

Der gute #DennisSchroeder erklärt, dass nicht nur die #Dateigrößen zu einer vollen #Festplatte führen können, sondern auch die #iNodes! Zudem führt er in seinem #Blog auf (https://schroederdennis.de/tipps-tricks/was-sind-inodes-bei-linux-dateisystemen-ext4-ext2-debian-ubuntu-filesystem/), wie ihr das Maximum an iNodes und die Orte mit zu vielen dieser Einträge auf dem #System erkennen könnt.

i will never not laugh about people building and working on some of the largest computers that have ever existed, regularly complaining about too few inodes...

#LSM avoids the approach of #syscall sc interposition unlike #Systrace as it
doesnt scale to multiproc kernel
is subject to #TOCTTOU attacks.
it inserts "hooks" (upcalls to module) at every point in #kernel where a user-level sc is about to result in access to say #inodes
