File System Design part 1, XFS

Posted by CmdrTaco on from the get-your-hack-on dept.

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. 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.)

    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.
