grub-install to both disks should do the job along with the UUID trick. Another option that I have been becoming more fond of lately is making filesystems with labels using the -L flag to mkfs, then using LABEL=foo in /etc/fstab. This has the added advantage that you can swap disks out completely and have the new one show up right where you wanted it. This is particularly useful for removable media where the FS label is used to determine the /media mount point. On 12/30/2010 05:27 PM, Jon Schewe wrote: > This doesn't help.
