I’ve been a long-time user of JFS, but have grown unhappy with it for various reasons. So, I decided to try out XFS. It proved no better than JFS or ReiserFS 3 with data integrity during a crash.
Next step: Reiser4. I’ve been using Reiser4 for the past month or so on three different machines. I must say that I’m quite impressed with it. It is a stellar performer and it also recovers well from crashes. I mount all my filesystems with the nopseudo option, which essentially makes Reiser4 have standard Unix filesystem semantics in every way. I’m very pleased with it so far.
