FreeBSD does not currently offer any form of clustered = filesystem support, nor would a SAN provide this in any case since = it=E2=80=99s just a shared fabric for a single set of storage devices. = You could front-end your SAN with a NAS, but that would simply re-export = the SAN as a shared file system such as NFS, which would let multiple = clients see it but still provide no fail-over if the NAS or primary SAN = controller died. You are trying to create an active/active fail-over system with multiple = modes. You cannot get there from where you are starting. This is = basically a =E2=80=9Cstart over=E2=80=9D proposition, and why folks like = NetApp and EMC sell a lot of fileservers to replace existing SAN = solutions. - Jordan
