This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enig12F72EC869AA2EBAFDECA6D5 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable Simon L.

For example, a simple partition layout might be: ad0 - first drive of size X ad0s1 - of size Y ad1 - second drive of size X ad1s1 - of size Y When creating a mirror of ad0s1 and ad1s1, gmirror writes its metadata on the last sector of both partitions, and creates the mirror device one sector smaller than Y. It can't write this sector if either of the partitions are in use (e.g. mounted). Actually, while writing it all down like this, it occured to me this can't be elegantly solved on the partition level, so sorry for the noise = :) --------------enig12F72EC869AA2EBAFDECA6D5 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.4 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFFykl1ldnAQVacBcgRAnRSAJ9wOscTIQXWpfqwVW4iGa01UkSdfwCcCHbx 4PsmJornd1ehrMHTRK/4cyY= =uEEo -----END PGP SIGNATURE----- --------------enig12F72EC869AA2EBAFDECA6D5--
