I would appreciate if you can tell me what > the problem is. A quick google search sent me to the freebsd projects page http://www.freebsd.org/projects, which links to Elephant under the "File system" section. That will send you to http://www.cs.ubc.ca/~feeley/DSG%20Web/dsg_p_elephant.html, which states that the elephant system is implemented as a virtual file system and is "available upon request." Have you contacted the people referenced on that page to see if you can get whatever you need to implement WMFS? One thing I noticed when I did the search is that I couldn't find much on elephant that mentioned anything later than FreeBSD 2.2.7, so the project may be pretty stale. You might want to also take a look at http://www.cs.ubc.ca/cgi-bin/tr/2001/TR-2001-07.pdf, about the mammoth file system which seems to be something fairly parallel to elephant, but may be available in a later version of FreeBSD. In any case, it looks like www.cs.ubc.ca is the place you need to start... Derrick To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
