I installed RH 7.3 some time ago on a test/lab server and did not create a rescue boot disk at that time. Now I come back to do this but can't seem to make one that will work. I have grub as the boot loader on this box, but the RH command to create a bootdisk seems to make a LILO boot disk, for what that's worth. Anyway, I take the values from my grub conf file and I come up with this command: mkbootdisk --mkinitrdargs /boot/initrd-2.4.18-3smp.img --kernelargs '/boot/vmlinuz-2.4.18-3smp ro root=/dev/ida/c0d0p2' --verbose 2.4.18-3smp This creates the disk, and when it starts up it says it will boot from /dev/ida/c0d0p2, which is correct, then it loads kernel, seems to be going OK, then stops with these lines being the last items on the screen: kmod: failed to exec /sbin/modprobe -s -k block-major-72, errno = 2 VFS: Cannot open root device "ida/c0d0p2" or 48:02 Please append a correct "root=" boot option Kernel panic: VFS: Unable to mount root fs on 48:02 Any idea why this can't mount? I'm guessing a syntax error but I don't know what it is. The box is a Compaq Proliant 800 dual P200 w/SMART array controller. Thanks, Scott . __________________________________ Do you Yahoo!? Yahoo!
