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;
- 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.
- 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. |
|
Note: The root password is 'initial'. |

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.ksWith 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

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!
