Assume I have: ad0s2 + ad2s2 =3D=3D=3D=3D /dev/mirror/disk0 ad4s1 + ad6s1 =3D=3D=3D=3D /dev/mirror/disk1 ad8s1 + ad10s1 =3D=3D=3D=3D /dev/mirror/disk2 disk0 is already has a filesystem which is mounted /usr/home.. Is it just a matter of: # umount /usr/home # gconcat label -v bigdisk /dev/mirror/disk0 /dev/mirror/disk1 /dev/mirror/= disk2 # growfs /dev/concat/bigdisk # mount /dev/concat/bigdisk /usr/home # cp -p /mnt/etc/fstab /mnt/etc/fstab.orig # sed -e 's/dev\/mirror\/disk0/dev\/concat\/bigdisk/g' </mnt/etc/fstab.orig >/mnt/etc/fstab > The output of 2.7 and 2.8 is different, because those disks aren't > really equal in size.

Yeah! ** BIG PROBLEM ** However, I need to move the mirrored disks from the test machine to the server and this is causing bootstrap problems. The drives on the test machine are connected to a pci ide card. On the actual server they will be connected to the onboard ide controller. Tried the switch and it gets to the BTX loader but halts real quick. How do I resolve this issue? Is this just on config file issue or something with MBR? Since when done, the machine will be using the onboard ide, two ide pci cards and a serial ide pci card will I be having issues with the drive order getting screwy??? Thanks for any help and pointers! Brent H.
