Porting it, yes. It is a prerequisite for CXFS. Whether XVM will be released as GPL has yet to be determined.

There are many different approaches to volume management. Neither of the three in question are similar enough to make integration trivial. I suspect the users will have several LVMs to choose from in the future. Just as it is the case with file systems. This has the advantage that the user can choose whatever implementation solves his/her problems. Dale> Now are we going to see SGI's XFS sitting on top of IBM's LVMS!? If IBM's LVMS will be using a kiobuf-based request scheme instead of buffer_heads, yes.

Neither does any of the other volume managers out there. -- Martin K. Petersen Principal Linux Consultant, Linuxcare, Inc. http://mkp.net/ SGI XFS, Linux/PA-RISC, GNOME
