Use tunefs instead; tunefs =E2=80=90L usr /dev/ad0s1f If you really want to use glabel, do it on an empty disk or partition. What you must understand is that 'glabel label' uses the last sector of the provider to store its metadata. So if you were to do e.g.=20 glabel label =E2=80=90v usr /dev/da2 A labeled device /dev/label/usr would be created. This is one sector smaller than /dev/da2! If you were to use newfs on /dev/da2 instead of on /dev/label/usr, the label would be destroyed once the last sector is overwr= itten! See the the EXAMPLES section of glabel(8). > GEOM: ad2s1a: geometry does not match label (255h,63s !=3D 16h,255s). > GEOM: ad2s1c: geometry does not match label (255h,63s !=3D 16h,255s). > GEOM: ad2s1: geometry does not match label (255h,63s !=3D 16h,255s). These are harmless, AFAICT. You can ignore them.
