Hi list,


For the first time in my life i tried to install Fedora with sw raid.

See below what went wrong.


Here is what I did:

Start with 2 empty 500GB sata disks.

Make sure nvraid is turned off in my BIOS.

Start an F9 install, creating 2 sw RAID partitions: md0 and md1.

md0 is 100MB and has an ext3 /boot.


This could be the blind leading the blind,

but just raided my centos5.

and was advised not to raid the /boot.

as it can get confused as to waht to boot from.

If you need a backup boot just rsync it to the second drive as

/boot1 (or similar)

Although you haven't told us "what went wrong" (IE errors, when in the boot process your system fails ect).

I would highly recommend using raid on your /boot partition, this will enable you to boot should you loose a disk, or boot with one disk unplugged for software updates and such (allows a restore point to boot back into the original should the updates / changes break some functionality on your system)

I would imagine that you only wrote to the MBR for one of your disks, and your bios is attempting to boot from the other. If this is the case your bios will report "no operating system installed" or something to that effect.

Enter your bios and change your startup order to boot from the other hard disk. (this process changes depending on bios make and manufacture so I'll leave you to figure it out on your own)


once you boot your OS from the drive where the MBR was written, open a terminal:

grub --no-floppy


you'll then see a grub prompt:

grub>


continue with:

grub> find /boot/grub/stage1
 (hd0,0)
 (hd1,0)
grub>

If you're disks are /dev/sda and /dev/sdb do the following to install grub on both:

device (hd0) /dev/sda
root (hd0,0)
setup (hd0)

device (hd0) /dev/sdb
root (hd0,0)
setup (hd0)
