He told me something about it in the year 2000? So Chris, any news? Would be nice to have a smaller journal on my root partition... -Dieter -- Dieter Nützel Graduate Student, Computer Science University of Hamburg Department of Computer Science @home: [EMAIL PROTECTED]

Actually some of the namesys coders did this, it works pretty well. The current utilities have support for it, I expect the patches will get fed into 2.5.x. The patches probably need a small update to reflect the latest cleanups in the kernel (a quick look didn't find it on the ftp site). -chris

It > would be nice to measure this. Speaking about measuring things, is there perhaps a document which discusses reiserfs performance, and how to look for things to tune etc... I'm currently running a very default reiserfs on top of 3 x 40GB IDE disks, and am wondering how hard it is working, and whether I could tune it to be better... I'm using 2.4.17pre8, ReiserFS 3.6.25 /proc/fs/reiserfs/device/super says: mount options: BORDER TAILS LOG on-disk-super says magic: ReIsEr2Fs (is this the 2.5 or 2.6?) Thanks, Adam
