There is, I've seen it, but I've lost the url.  IIRC, the "pro" for jfs
was that it had the lowest CPU usage.

If you want to tinker with logical volumes and journaled file systems to
learn more about AIX, I'd go with jfs.  I believe it's related but not
identical to the jfs in AIX.

I've used both AIX and Linux, and like both.  There are some interesting
differences in their LVM, but in general your idea is sound.

I'd recommend you try all of the file systems and compare them yourself.
