File System Design part 1, XFS

rchapman writes "Generally, file systems are not considered "sexy." When a young programmer wants to do something really cool, his or her first thought is generally not "Dude, two words... File System." However, I am what is politely termed "different." I find file systems very interesting and they have seldom been more so than they are right now. Hans Reiser is working on getting Reiser4 integrated into the Linux kernel, the BSD's are working on getting a journaled file system together, and Sun Microsystems just recently released a beta of ZFS into OpenSolaris. "

Oh, snap.

Oh, snap. Somebody's not running Soft Updates. :-)

(Yes, I understand that Soft Updates is not technically metadata journalling as practiced by the Linux people. No, I don't believe there are a significant number of practical situations where the results will differ.)

Blatant error

[lostlogic]

Sector size on hard disks is 512 bytes, not 512kbytes. WTF, don't act like an authority and be a dumbass. Imagine the data waste if we actually had 512k physical sectors on disks.

Also the scaling numbers are completely hokey.

division

With everyone and their parrot talking about RAID these days, it would've been fun if some sort of dual array would work as ONE filesystem; where one(++) redunant set took care of the balancing/tree'ing, etc., (separately,) and the other(s) kept the actual files. If there was _yet_ another set (a ++third), with the relevant META-information belonging to the files, you would imagine it to be a step forward to what is now, well; I can, anyway..

NSS for Linux

[marquis111]

NSS has been ported to Linux too. That's an another modern industrial-strength filesystem with features sorely needed by Linux.
