"Learn the intricacies of the AIX file system framework. Every operating system provides a native kernel framework that kernel developers have to understand and adhere to when developing a piece of a kernel component for that operating system. This article sheds some light on the AIX file system framework. You need to understand the framework in order to develop a new file system, or to port an existing file system to the AIX operating system."

I'm not familiar with the history of the volume managers. But from this link: http://www-03.ibm.com/servers/aix/products/aixos/whitepapers/lvm_ve.....
I assume IBM developed the LVM by them self. Not 100% sure at all. The IBM FS (JFS2) is developed by IBM.
Well, I have seen those 'translation' docs for HP-UX LVM versus VxVM too, so I don't know if that shows much. What I did find that is interesting is this old thread:
http://www.osnews.com/comment.php?news_id=13874&limit=no&threshold=...
In which one of the posters presents a somewhat convincing argument that the LVM in OSF was from IBM. Of course this is around 1990 and so printed sources are going to be the problem. At any rate, I do believe IBM has licensed Veritas IP, regardless of what the LVM looks like. But I am much more sure that this is the case with Tru64 (and of course HP-UX) than with AIX.
The IBM FS (JFS2) is developed by IBM.

Thought the IBM JFS2 and HP-UX JFS are totaly different.
Agree 100%. What I am not totally clear on is how close Linux JFS is to IBM JFS2.
