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

Admins were not happy. Initial attempts to resolve the issue by replacing files with hardlinks also failed due to ext4’s 65,000 hardlink limit.

New article: Btrfs 🌳

The Linux filesystem that never overwrites data. Every write goes to a new location.

Snapshots, RAID, per-block checksums with auto-repair on RAID, atomic transactions, all built into the filesystem.

Btrfs | Internals for Interns

In the previous article , we explored XFS—a filesystem built for extreme scale that divides the disk into independent Allocation Groups, each with its own B+ trees for free space, inodes, and extent tracking. XFS, like every filesystem we’ve covered in this series, shares one fundamental characteristic with ext4, NTFS, and FAT32: it modifies data in place. When you update a block, the new data overwrites the old data at the same disk location.

Unix domain sockets operate differently from regular files. The permissions on the socket file itself determine access, so even if the directory is mounted as read-only (:ro), any process can still connect to the socket if it has the appropriate permissions

FUSE Loopback is Incomplete, Breaking NFS

Surprisingly, it’s not possible to make a loopback filesystem in FUSE that is complete.

Does anyone know what's the backstory of the 260 characters absolute path length limit in #windows? Feels like a rather arbitrary limation.

It ends up causing all kinds of problems in various software. In #git I managed to get it solved by activating longer paths in registry, but #unity3d has the path length limit hardcoded apparently...

用 Claude Code 修 NAS 的 ZFS filesystem

這兩天在台灣的 Threads 上面很紅的一則文章,作者 (看起來是 cofounder) 公司的 NAS 掛了,看起來不是壞軌,是遇到 ZFS metadata 故障的問題 (ZFS software bug?),問國內的救援公司大多都沒有辦法處理,最後是自己找了一張 HBA 卡把十二...

Open-Source replacement for Amiga CD filesystem: ODFileSystem

Stefan Reinauer has written a modern open-source replacement for the Amiga CD filesystem, with support for ISO 9660, Rock Ridge, Joliet, UDF, HFS, HFS+ and virtual CDDA audio tracks.
