I can heartily recommend reiserfs on kernel 2.4 for Intel and Sparc. My spam filtering setup currently has 27K files in a quarantine dir, and it works just fine. In a year and a half over 50 machines I've had three corrupted reiserfs filesystems, none of them on production machines, at least one of which I can blame on a bad disk. I would not be surprised to learn they were all bad disks, because the disks are five+ years old. For the last one I moved the bad dir aside where it sat peacefully for a week, and when I fsck'ed it the more aggressive mode of fsck coredumped partway through and it became unaccessable. I then restored it from the tar I had made prior.
