Regarding a filesystem mounted on multiple boxes, check out DFS; there's a spec available from the Open Group in the UK for $58.00: http://www.opengroup.org/pubs/catalog.saved/p409.htm If you allow multiple R/W mounts, it's certainly not trivial. As Kirk said, you need a strong coherency mechanism; DFS uses a token mechanism invented, AFAIK, by Locus Computing Corporation. I work on the former Locus clustering stuff (for Compaq, these days), so I can't really contribute, but I know there are white papers and other docs out there. -- Frank Mayhar frank@exit.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
