However, one has to clearly distinct JFS from JFS2... (at least in the AIX world, see wikipedia which states 'In the other operating systems, such as OS/2 and Linux, only the second generation exists and is called simply JFS.[3] This should not be confused with JFS in AIX that actually refers to JFS1.'

the AIX I worked with, 5.3L, supports both JFS[1] and JFS2... They are very similar structurally, JFS2 just supports larger volumes.
