As pointed out before, DRBD can do active/active, so long as the filesystem on top support it (GFS2 and OCFS2). The DRBD team even has documentation to get you started: http://www.drbd.org/users-guide/ch-gfs.html http://www.drbd.org/users-guide/ch-ocfs2.html _______________________________________________ gnhlug-discuss mailing list [email protected] http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
