In a cluster, the disks would reside in multiple machines, and the 'file system' would withstand any one of those machines going down. That is quite a bit different than just wanting a bunch of clients to have concurrent access to a single disk array. If you explain your use-case in more detail, we may be able to guide you in the right direction. --=20 Allan Jude --uwrg0P5ODEVL921K6DrL39Cl0LCCjugsE Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (MingW32) iQIcBAEBAgAGBQJUK1WCAAoJEJrBFpNRJZKfY6YP/1I225shSB9C0Vnkw9oNBLxy JfJ7nxyghsFcCseUe+N7ggYCMxr6DO+z4RTG4XuCJ2v7ntlcBkdO8LwnuUL+blkY noGpPzJHuAsX/iujTsNe2XPukuCK3guEFKyO1MMbG1WQnNbRCq3F5zPwOoVUYhHC urFZeoSLYnZWFL6deFJcrTxDVuXh0gc/O/d9lOIieWUVtgFDnBLLmo6LZ6t9qc0P EBOsM28dINchOgOoN2fLyhkvISN1ZwbIN6p8HNM2vYsWZg7toOlWjKr4KUMtyDvp KEpFpBMTOI058qxsNDqjgpboj5izhp7N2o7rtFp1ks2JR0ar1Y2iHzm8lTTuXpqQ Rp9xfhDt8D7yxy3zDI49+mMRCHWnqqg8GGaC5qCs0urd4SGto4ZzV6X91qdnrmSo /adc4PZtJYHECiSB14D0tMDiDJW/w40F/j1oXlA87OwbQtrbDgomq/Kj4JnPAN/3 8vxF3oFoQO5fMfgjmIV2MfUsbt7F9zYFoiZlG0Yyw5rqyNz00nKiTj1p4eFtpaNR isEsIjBCjF3Th8mqtwfWeWMLX99UeWN6XMrMVKhxnT89jwgvp9cQ710Q+ZX/teZR UjBR7I1HFa01wmCcwy/4lTsoI8eaD+KGGAwUwjXXdHlOpjqJttPxdP6JNfHWR0Gh kA/buRftqIGfw+Y88EFx =qAKB -----END PGP SIGNATURE----- --uwrg0P5ODEVL921K6DrL39Cl0LCCjugsE--
