The problem is that I can't make the root partition (i.e., "/") for the hard disk writable. I can mount other partitions on the hard disks as writable. The hard disks contain a mirrored GEOM file system. In creating the GEOM mirror I mapped /dev/da0 to /dev/mirror/gm0 and then mirrored gm0 on /dev/da1. (All of the GEOM configuration was done under 6.1 and the system was recently upgraded to 7.0). The fstab I created in the Fixit shell contains the following lines: /dev/da0s1a /mnt/root ufs ro 0 /dev/da0s1d /mnt/var ufs rw 0 Fixit# mount /mnt/root Fixit# mount -u -w /mnt/root mount: /dev/da0s1a: Operation not permitted. Mounting the /var file system works as expected. What can I do to make /mnt/root a writable file system? Thanks, Brian
