Hey Shawn I have run into this problem b4 too. Check out 'Step 25' at this link ... http://togami.com/~warren/guides/remoteraidcrazies/ You can also verify if grub is 'really' installed on your disks by doing a 'dd if=/dev/hda bs=512 count=1' on each disk. If grub is really installed you should see something like this - ---snip--- [root@trinity root]# dd if=/dev/hda bs=512 count=1 ïÐØï|ï8u ïuï|tAÊï|1ØÐ @|<tïy}ïtTAUïZRrIUuCA|ïït7fL|ïfD|ïïfïpf1 DfD Bïrpïs ï|ïf@fD1ïïï@ïïffD|f1ï4T f1ïtT D ïL ;}<T ïÑl Zt pïÛïr*ÃH|`ï1a&B|}ïï}ïï}ï}ïïGRUB GeomHard DiskRead Errorï<uïïv? ?/ ï~} KK4ïLL#/-U1+0 records in 1+0 records out ---snip--- Don't worry about the diskread error message - its ok - it means that grub is installed there.

Hope that helps :) pantz
