That is, if I have a 2/3 quorum, and files A and B read '1' while C reads '2', can the mere act of reading that sector be used to write '1' into C?= Obviously, this should be an optional mode, not enabled by default; but I could envision creating a self-healing redundant array via this method.= --=20 Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org --qL338jbow838rmsndh5lqh6PKbna9luue Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 Comment: Public key at http://people.redhat.com/eblake/eblake.gpg Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBCAAGBQJTB9frAAoJEKeha0olJ0NqhqkIAIy9t5DDxYZkVvkwSw8GOB/4 cvirFGE814RI847beiFxSvzg0ZT7UWCZT+SquRoadVjK2VuYe1c7thAoVZOBmK/H /WIyINWI88bKX2i567RlskzZE4hwoQrcMqxgi0cqfdhtFi4LLL/wwMXYjQfe1f4S +6YqmksL4pHM2RzJieGo5Jm/Rw98OS+fxuoLAKterK7l9ZZ2TZeFfYh+d6JLeTWA yq4DYPomhwkJqpgXLe8z8aYt9pX/eFrOqabiE48RxLSFL5DYmh0mmHonW/whvfwx KPE1mY42g37qgueE0xnuhgnNoGwis/fQR0aCuCzpKnWf+Nh1ZWw6rqrird3JyNk= =qKjB -----END PGP SIGNATURE----- --qL338jbow838rmsndh5lqh6PKbna9luue--
