After successfully getting RAID 1 to be bootable on my Fedora 10 setup, I ran the update and one of the things updated was my kernel. It appears that the new kernel was added to the grub/menu.lst for the first HDD, but not for the second. Does this new kernel have to be added to the second HDD manually? Or was my bootable RAID not as successful as I hoped? Here's my new menu.lst: # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE: You have a /boot partition. This means that # all kernel and initrd paths are relative to /boot/, eg. # root (hd0,0) # kernel /vmlinuz-version ro root=/dev/sda3 # initrd /initrd-version.img #boot=/dev/sda default=0 timeout=10 splashimage=(hd0,0)/grub/splash.xpm.gz hiddenmenu title Fedora (220.127.116.11-170.2.5.fc10.x86_64) root (hd1,0) kernel /vmlinuz-18.104.22.168-170.2.5.fc10.x86_64 ro root=/dev/md2 rhgb quiet initrd /initrd-22.214.171.124-170.2.5.fc10.x86_64.img title Fedora (126.96.36.199-117.fc10.x86_64) root (hd1,0) kernel /vmlinuz-188.8.131.52-117.fc10.x86_64 ro root=/dev/md2 rhgb quiet initrd /initrd-184.108.40.206-117.fc10.x86_64.img title Fedora (220.127.116.11-117.fc10.x86_64) root (hd0,0) kernel /vmlinuz-18.104.22.168-117.fc10.x86_64 ro root=/dev/md2 rhgb quiet initrd /initrd-22.214.171.124-117.fc10.x86_64.img It appears that the first stanza following "hiddenmenu" was added after the kernel update.
