It doesn't have to be "weird" behaviour, depending on whether gvinum checks parity on reads (does it?). If it does, it will only have to ignore checksum errors in this case. I suppose people will want to run utilities like diskinfo -vt on the volume with invalid parities so it's not a theoretical scenario :) --------------enigA98048F3A1A0F141F5ECCCBA Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFJQjfsldnAQVacBcgRAmAkAKDcZeY7tVtgbxu4bpFH/m1m50zj3gCeKL6H PzbmxYNjZHER22QRw/AvMYE= =YTrG -----END PGP SIGNATURE----- --------------enigA98048F3A1A0F141F5ECCCBA--
