Нечаянно удалил все файлы в папке сайта на сервере. В прошлый раз я потерял очень ценный рабочий скрипт-файл и это было в позапрошлом году. Extundelete и testdisk ни черта не помогли. Не тогда, не в этот раз. Пришлось опять через grep искать по подстроке на всём жёстком диске содержимое файла.

Вот примерная строка запуска, если кому надо:
grep --binary-files=text --context=1350 'SELECT * FROM posts WHERE post_hidden < 2' /dev/sda1 > found_data1

Ext4 конечно плоха в этом плане. ReiserFS 3.6 раньше позволяла почти все удалённые файлы восстановить. Интересно как в этом плане дела обстоят у BtrFS и XFS?

@farooqkz Having read-write capability for a non-native #fileSystem does not mean all the features would be supported.

Written other way, I would be wary of using #EXT4 on #FreeBSD for longer time than needed as I do not think all the journaling support is available. I would love to be wrong on this!

UFS of FreeBSD is different than of OpenBSD; cannot interchangeably use them. Also https://freeradical.zone/@ax6761/114130069307988012 .

Anyway, I was having big issues with trying to create an #EXT4 file system and the same problem was occurring on multiple devices, indicating that it wasn’t the device that was at fault and I concluded that it must be something to do with #mkfs.ext4.

Thanks @vkc

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.

So, I'm currently installing WSL in an attempt to get Windows 11 to view various ext4 filesystems, as I do a lot of stuff with Rasperry Pi machines. This feels...kinda wrong. I hope it works though. I know just enough to be dangerous, but not enough to be a true expert.

I wonder if anyone can help me with a #Linux #USB issue. I’ve got a new flash drive on which I want to put a Linux directory structure on {with #EXT4, encrypted if possible). However, using the #GNOME #disks utility to #Format it apparently works but when I go into the disk’s root directory, I can’t create any files – I get an input/output error. If I reformat the disk as a #FAT (windows(disk then it works again and so I’m thinking there must be some problem with the utility I’m using.

Here’s a thought I’ve just had on file systems for #Linux: if I have no need for advanced features like subvolumes or snapshots or built-in support for multiple devices, is there really a point to thinking about which file systems is good for an Average Jane such as myself? I don’t exactly consider myself lacking in bandwidth, so surely the difference only starts to matter at scale? #btrfs #ext4 #xfs

Guess who'll have to format a #selfhosted server today! In related news, good thing I have daily backups. In other related news, I was today years old when I learned #Btrfs was considerably slower by default than #Ext4

Sinceramente, esto es algo que no entiendo, ya que #EXT4 es el sistema de ficheros empleado de manera predeterminada por las tres distribuciones #Linux más utilizadas en entornos domésticos: #Ubuntu, #LinuxMint y #Debian. https://www.phoronix.com/news/Limine-9.0-Released

Edit: I'm going with LUKS + BTRFS. Thanks for the responses!

Which file system should I use for an encrypted root partition on Linux for a single disk (no RAID)?

I typically use LUKS + ext4.

I've also used encrypted BTRFS and ZFS but never worked with them to any extent beyond getting them setup. I see distros such as Fedora are now defaulting to using BTRFS.

I'm seeking some advice: Should I stick with ext4? Or use BTRFS? Or ZFS?
