Commands I use to explore Linux filesystems - Both.org

As a SysAdmin, I need to manage the filesystems on the hosts in my home lab. There's usually little to do, but when there is it can be interesting. For the most part it's just a bit of monitoring to ensure that none of the filesystems are getting close to that 80% full mark at which performance tends to suffer.…

🎨 #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.

"TernFS:
- Is designed to scale up to tens of exabytes, trillions of files, millions of concurrent clients.
- Stores file contents redundantly to protect against drive failures.
- Has no single point of failure in its metadata services.
- Supports file snapshot to protect against accidental file deletion."
- Can span across multiple regions.
- Is hardware agnostic and uses TCP/IP to communicate.

#Linux 6.18 Will Further Complicate Non-#GPL Out-Of-Tree #FileSystems
A patch queued up for Linux 6.18 merge window removes #write_cache_pages. In turn this will cause issues for #nonGPL out-of-tree file-systems for writing dirty data from the page cache. After the #NTFS3 and #Bcachefs in-tree users of the iterator were moved off of it, for Linux 6.18 the "write_cache_pages" will be removed that is depended upon by out-of-tree, non-GPL file-systems.

Linux 6.18 Will Further Complicate Non-GPL Out-Of-Tree File-Systems

Out-of-tree file-system drivers not licensed/compatible with the GPL will have a new obstacle to deal with come time for Linux 6.18 later this year.

@lambdacalculus also "#HardwareRAID" only exist for garbage OSes like #Windows that don't have a proper #VolumeManager nor proper #filesystems!

Hey Fedi!

I need to copy some TBs of data (incl. large files) from an NTFS drive to SOME_FILE_SYSTEM and then that SOME_FILE_SYSTEM to Ext4. (*)

Is there a value for SOME_FILE_SYSTEM that is better than the other choices?

(*) Copying directly is not an option. The drives are all in the same computer.

In-memory Filesystems in Rust

I’ve been working on a CLI tool recently, and one of the things it does is manage files on disk. I have written a lot of file management tests for Bundler, and the two biggest reasons that the Bundler test suite is slow are exec and fstat. Knowing that, I thought I would try to get out ahead of the slow file stat problem by using an in-memory filesystem for testing.
