--4zI0WCX1RcnW9Hbu Content-Type: multipart/mixed; boundary="5QAgd0e35j3NYeGe" Content-Disposition: inline --5QAgd0e35j3NYeGe Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Hello I have a disk with two slices since I need more partions than on slice can hold. I have one 20GB and one ~200GB but when I edit the disklabels for the two slices it looks like disklabel(8) get the total size of the slize wrong (sectors/unit). It uses the size of the entire disk instead of the slice causing disklabel to complain about the c partion being wrong size. It looks like disklabel gets the sectors/unit directly from Geom trough ioctl so I have put the output of sysctl -b kern.geom.confxml on http://simon.nitro.dk/freebsd/files/misc/geomconfxml (since it is a bit large for a maillinglist). The problem disk is da0 but ad0 on the same system seems to have the same behavior. Anybody else seeing this ? This on a -CURRENT from 25/4. --=20 Simon L.
