Setting Boot 1st From Master, Second From Slave
 

Hello,
I am in the process of setting up a master/slave server that's running redhat 9. The partition setup is as follows:

hda
/
/home
/boot # boots from MBR
swap

hdb
/
/home
/boot # boots from boot partition
swap

I am setting up a cron to daily clone hda to hdb using the dd if=/dev/hda of=/dev/hdb method.

I would like to set the boot loader to automatically boot from master and then the slave if the master hd fails.

Would Grub be the best way of doing this if it's doable in the first place?


Now I know a raid1 method would be preferable to this workaround but, we have 2 80 g harddrives and we are hosting one site that could easily baloon to 20 g in the next year by itself. If I go w/ a raid1 then I'm only working w/ 40 g of space.


Thanx,
Clem
