Why, in a nutshell, is Reiser FS good enough for SuSE, but not good enough for Linus? Is Linus being ultra cautious, or does Linus know things about Reiser FS that SuSE doesn't? I read recently that Linus was actively considering putting RFS into the 2.2.4 kernel, but why is it not in there now since SuSE have done the work?
I got a couple of question regarding new Reiser journaling file system. Is somebody of you actually using it?
Yes, we use it internally on quite a lot of machines. I have a reiserfs partition on my personal workstation:
grimmer@Wiles:~ > mount | grep reiserfs /dev/sda4 on /space type reiserfs (rw) grimmer@Wiles:~ > df -h /dev/sda4 Filesystem Size Used Avail Use% Mounted on /dev/sda4 4.4G 1.2G 3.2G 27% /space
Our main development server also runs on reiserfs:
grimmer@Hilbert:~ > mount | grep reiserfs /dev/sda3 on /work type reiserfs (rw,noatime) grimmer@Hilbert:~ > df -h /dev/sda3 Filesystem Size Used Avail Use% Mounted on /dev/sda3 235G 161G 74G 69% /work
Is there any advantages Reiser FS over EXT2 in terms of speed, ability to recover after crash?
Yes, that's its main intension :)
It is significantly faster because it is using a balanced tree algorithm to store the files. And since it is a journaling file system, you do not have hours of filesystem-check after a crash. Pretty neat!
