Just some ideas: For Linux there are some cluster FS like GFS (RedHat, GPL) GPFS (IBM) OCFS2 (Oracle, GPL) Veritas (without support on certain distr.) CXFS (SGI) I know there are more, however, I haven't used any of them. There is also something like drbd, have a look at http://www.drbd.org/ http://www.linux-ha.org/ Simon ---- Cyrus Home Page: http://asg.web.cmu.edu/cyrus Cyrus Wiki/FAQ: http://cyruswiki.andrew.cmu.edu List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
