@mkwadee@mastodon.org.ukI managed to create an #encrypted #Linux #Filesystem on a #USBStick. The reason I wanted this is that I want to back up some directories, which contain secure information and also #NTFS, the one that comes on most drives, doesn’t know how to handle #SymbolicLinks properly. I don’t need or want to share the stick with any non-Linux machines.
SysV filesystem is being removed from Linux 6.15
In the old Unix days, there was a filesystem that implemented the Xenix FS, Coherent Unix FS, and SystemV/386 FS. It allowed file organization and access that provided the data storage service that allowed applications to access mass storage and its contents, including files and folders.
The ex-maintainer of this filesystem support for Linux systems had orphaned the filesystem maintenance back in 2023 [lore.kernel.org], when the maintainer said that there was no way to test it, with the possible removal slated in the future.
The future has come, and Jan Kara from the SUSE team [git.kernel.org] has pushed a commit to the VFS git that removed all code for the SysV support for Linux, which confirms that, starting from Linux 6.15, you won’t be able to access these legacy filesystems. This is because, back in 2023, Google’s Linux kernel fuzzer, syzkaller [github.com], has automatically reported a bug [lore.kernel.org] in SysV where the sleep function was called from an invalid context.
As nobody is using this filesystem in their Linux installation, it’s safe to remove this filesystem support from the kernel. This only affects computers that have both Linux and a legacy Unix system that uses this antique filesystem installed, but the amount of such computers is very small.
Once Linux 6.15 gets released, you won’t be able to use any partitions that use this filesystem.

hey hey #Linux #FileSystem #ZFS #RAID #XFS entities! I'm looking for extremely opinionated discourses on alternatives to ZFS on Linux for slapping together a #JBOD ("Just a Bunch Of Disks", "Just a Buncha Old Disks", "Jesus! Buncha Old Disks!", etc) array.
I like ZFS but the fact that it's not in tree in-kernel is an issue for me. What I need most is reliability and stability (specifically regarding parity) here; integrity is the need. Read/write don't have to be blazingly fast (not that I'm mad about it).
I also have one #proxmox ZFS array where a raw disk image is stored for a #Qemu #VirtualMachine; in the VM, it's formatted to XFS. That "seems" fine in limited testing thus far (and seems fast?, so it does seem like the defaults got the striping correct) but I kind of hate how I have multiple levels of abstraction here.
I don't think there's been any change on the #BTRFS front re: raid-like array stability (I like and use BTRFS for single disk filesystems but) although I would love for that to be different.
I'm open to #LVM, etc, or whatever might help me stay in tree and up to date. Thank you! Boosts appreciated and welcome.

@Purple@woof.techOk so I've been having this weird issue with network SMB Shares on MacOS, where new files are "ghosts" until I explicitly request a new file listing
% touch test; mv test test2
mv: rename test to test2: Input/output error
Does anyone have an idea what it might be? It's making me go crazy
I've posted on stack overflow about it here: https://apple.stackexchange.com/questions/476627/macos-mounted-smb-share-is-not-directly-aware-of-new-files/476633

Reading these benchmarks makes me regret my choices in file systems

Are the thousands-of-tiny-files split into many small subdirs, or just individual directories with thousands of files in them?
If the latter, then depending on the #filesystem type, Linux can be quite slow at looking up and opening files in those dirs - if the proxy (or whatever) is expecting near-instantaneous results, it might be sad.
ext2/3/4 are problematic with the tons-of-files-in-a-dir issue, for example.
@Natanox@chaos.socialIs there a #Linux file system that's able to repair files in case of corruption when used on a single disk?
I got an older 4TB disk with "pre-failure" SMART values but no runaway sector corruption that I'd like to use for temporary file storage of less important data. Still, a file system that could recover big files would be nice so a single bad sector doesn't immediately kill for example a >3gb file.
Any recommendations?

I have a friend who wants to move full time to a Linux distro. She currently has several drives all as exFAT and wonders if she should reformat them to ext4.
What should she do?
She describes her drives as:

Do NOT use #ReFS!
2 days ago I've updated to #Windows11 24h2 from Windows 10.
I have a drive for all my projects with ReFS #filesystem on it.
After an update my ReFS drive is not recognized by Windows. System says that partition is damaged and have to be reformated.
After hours of googling and reading forums I found info about that #Microsoft just silently dropped the old ReFS driver and replaced it with a new one which is not compatible with older partitions.
Windows Server 2022 at the same time does a silent upgrade of your volume without any problems.
If you are in the same situation, you have two options:
1. Boot from Windows10 live image and rescue your data;
2. Get a Windows Server VM, attach the whole physical disk with ReFS partition to it, boot and wait about 5 minutes (or try opening your refs volume inside the VM).
