CentOS 6.6 64-bit Won’t Install On A 3 TB Disk

Hello everyone,

I’m having an issue getting a C6.6 install to work on a 3 TB dual hard drive system, raid 0. I’m hoping that someone here can help.

So, I install as normal, but then reboot, and it comes to a grub prompt. Going into the system via Linux rescue, I see that most of the files dealing with the kernel haven’t been installed.

I asked the maker of the server and he said that they have noticed this happen recently. A solution is to put the kernel files on a thumb drive, and then point the OS to look for them there.

I have yet to try it, but is there a better way to deal with this issue that anyone else has done?

  • Have you tried manually putting the kernel/initrd files where they are missing from?

    Having said that, relying on this machine as a server seems questionable under the circumstances. :-)


  • 1: Is this system booting UEFI or BIOS?
    2: Is the disk partitioned with MBR or GPT?
    3: Is /boot on its own partition?

    3TB drives are larger than MBR and BIOS properly support, so they’re only really expected to work on a system partitioned with GPT and booting via UEFI. And in that case, /boot and /boot/efi need to be individual partitions.

  • Hi Gordon,




    Ahhhhh, OK. Well, I have some work to do this afternoon. Thanks for the very helpful tips!

  • Not exactly true – they work fine with an MBR but you can access 2/3 of the drive. Also it is not necessary to use UEFI to boot.

    You can have a fakeout mbr that is used for a standard bios boot.
