Hi, You can't use vinum to mirror the root filesystem. You will need a hardware solution to do that. What I have done in the past is to manually edit the disklabel on the second drive so that is identical to the first (assuming the drives are the same, mind you they dont' have to be) and install a bootstrap on it. You can make whichever of the filesystems you want type vinum except the root filesystem. As normally, the contents "/" does not change all that often, I then set up a script in /etc/periodic to copy one to the other. This works best with scsi drives as they are assigned as they discovered at boot time and you don't have to mess around with /etc/fstab and swapping drives if the first drive fails, just disconnect it and the system will boot from the second drive (which is now becomes the first). Hey, it works. Rob. At 15:06 20/04/01 +0200, danny@i-p-d.nl wrote: >I have been trying to setup vinum to mirror my first harddisk on a >second identical harddisk.
