The Goal

A problem I had been struggling with since the release of RHEL/CentOS 7 is how to install on a software RAID 1 array such that either disk could be used to boot.

The Problem

There are two problems;

  1. The default behaviour of anaconda prevents the creation of the biosboot partition on both disks. When I tried to to manually create the partitions by dropping to shell, anaconda would later fault out and the install would not complete. To get around this, a kickstart script is needed, which was booted off of a PXE server.
  2. After the kickstart install, only one disk was bootable. Trying to install grup on the second disk caused a crash.

The Fixes

Install

I have a PXE Server already, so I decided to create a kickstart script and added an entry for it.

The kickstart script used to perform the CentOS 7 install was:

Note: Update this to match the IP of your PXE server and update the partition sizes, host name and desired VG name to what you want.

To boot off of this kickstart file, I used the following PXE boot entry:

LABEL c7_x86_64
        MENU LABEL ^2) CentOS 7 x86_64 - an-nas02
        KERNEL boot/c7/x86_64/vmlinuz
        APPEND initrd=boot/c7/x86_64/initrd.img inst.repo=http://10.255.255.254/c7/x86_64/img/ ks=http://10.255.255.254/c7/x86_64/ks/an-nas02.ks

With this in place, boot off of the PXE server, select the entry and go grab a coffee. When you get back, the install should be finished.

Booting Off Both Disks

After the install completed, I tested booting off of each disk by using my mainboard's BIOS manual boot device selection (pressing <F8> during the BIOS boot process). It turned out that I could only boot off of the second disk, not the first.

Easy enough, I figured. I booted the OS and tried to install grub2 on the the first disk:

grub2-install --no-floppy /dev/sda
Installing for i386-pc platform.

Well foo.

After some digging around and some help from randomuser on freenode's #centos channel, the problem turned out to be that /boot was on a Logical Volume, which *should* work. The fix was to prevent grub2-probe from looking for the filesystem probe.

grub2-install --grub-probe=/dev/null /dev/sda
Installing for i386-pc platform.
Installation finished. No error reported.

With this, I could properly boot off of either disk!
