Craig, I spoke with an XFS developer the other day on the (what else) #xfs channel. Same server as hosts the #mandrake channel. We discussed what you just now brought up; file attributes. I found out several things, one was that the minimum size of an XFS partition was 6 megs. This information is not readily available...I did RTFM before I resorted to cruising irc. The other was that he was positive that the chattr command would be unable to set an "i" attribute under XFS. He seemed unsure as to wether there were other unsupported attributes or not. Just thought I'd bring this up so you can add it to your information store if you haven't already. I've been looking very strongly at XFS; however, I've gotten the concrete impression that ext3 is a very hard to break filesystem. It seems very robust; at least on this system. I was motivated strongly to write this, because I had a crash just a short while ago. I've been trying to get a game to work, Heretic 2 for Linux. I got it installed and downloaded the latest update. Unfortunately it was statically compiled for glibc 2.1. 640x480 worked, but when I moved to other resolutions, it pumped out alot of errors and then vaporized. Three or four times later, I finally got it to attempt a load into 800x600. The entire system locked. If this had been an ext2 system I would have been sweating....especially since I have two drives striped with no RAID1 mirror. I powered the system off and on, then it booted. I did not even get one error message. Absolutely nothing out of the ordinary; it was like a normal boot. This isn't the first time I've had lockups while trying something marginal or power failures while working. It's happened before. In every single instance, ext3 has cruised back into operation as if oblivious that anything had occurred(knock on wood). Ext3 continues to strike me as extremely robust. I'm highly curious about XFS, but then on the other hand I've been told that it's very poor judgement to drop pristine FS performance in exchange for an unknown when involving live data. In fact I just finished telling myself that a few minutes ago. ;) I'm definitely going to try XFS, but before I do I plan on having a mirror drive installed that RAID1's the main stripe array. Good luck...
