From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I used ext4 extensively in an HPC setting a few jobs ago (many petabytes). Some of the server clusters were in areas with very unreliable power grids like Indonesia. Using fsck.ext4 had become our bread and butter, but it was also nerve wracking because in the worst failures that involved power loss or failed RAID cards, we sometimes didn’t get clean fscks. Most often this resulted in loss of file metadata which was a pain to try to recover from. To its credit, as another quote in this thread mentioned, fsck.ext4 has a very high success rate, but honestly you shouldn’t need to manually intervene as a filesystem admin in an ideal world. That’s the sort of thing next gen filesystem attempt to provide.
