Error Installing - An Unknown Error Has Occurred

Post by EverydayDiesel » 2014/07/12 07:24:17

Hello, I am trying to install "CentOS-7.0-1406-x86_64-DVD.iso" on a server but it gives me "An uknown error has occured" when installing boot loader.

it also gives this information
"This program has encountered an unknown error. You may report the but below or quit the program"

If i click on more info it has this information

anaconda 19.31.79-1 exception report
Traceback (most recent call first):
File "/usr/lib64/python2.7/site-packages/pyanaconda/bootloader.py", line 1591, in install raise BootLoaderError("bootloader install failed")
File "/usr/lib64/python2.7/site-packages/pyanaconda/bootloader.py", line 1605, in write self.install()

and then it goes on and on with information

Does anyone know how i can get centos installed?

Thanks in advance.

Just try it again. And maybe after that again.

I got the same message several times, but at last was able to install it, from the same iso that gave these messages.

Please detail exactly all the choices you made during the installation setup. Also what is your hard disk set up: how many? how are they attached? how are they partitioned? do they already contain a boot loader? Is your machine set up to use UEFI or BIOS? Secure boot?

Its a minimal install (everything default)
Install is to a 500gb hard drive(mechanical)
BIOS RAID set (stripe)
automatic configure partitioning


I am not sure if it matters but i noticed on the 2nd line of the install (white screen) it says
" [5.177507] i8042: No controller found"

Server is a 5038ML-H8TRF

Drive is a segates ST3500321CS



I also tried to install Centos 6.5 64 bit but it hangs on the screen where it probes the devices (drives)

I did install several times 10+ with different options/filesystems but nothing seemed to work

Bios RAID sounds like fakeraid.
If this is the case you need to disable it and use md RAID. You cannot boot off a RAID 1.

I only have one 500gb drive in there so I guess the box setup its own software raid.

I am looking through the bios and i am not really seeing where it is an option to disable the raid.
The SATA controller configuration gives me the following choices:
AHCI
RAID
IDE

The default is AHCI. If i use IDE it tells me there are no drives installed, if i use raid then it errors the same as AHCI
I honesty dont need any raid capability since they nodes are redundant

where/how do i select mdadm raid?

If you have only one drive you don't want RAID.
The BIOS should be set to AHCI.
If you had it set to RAID, you need to remove the RAID metadata.
Set the BIOS to RAID. Remove the drive from the RAID. Set the BIOS to AHCI.

Thank you for the response however there is no place in the bios to create/delete an array (I never created one either). I dont see anything in the boot sequence either like i have before.

This says it works with redhat 6u5
http://www.supermicro.com/support/resou ... 38ML-H8TRF

For what its worth, i installed BSD on it thinking it would wipe the disk. It installed with no problems.

I then installed without boot loader (since boot loader is failing) but the server just boots to a flashing cursor.

Im at a loss here

the bios is set to AHCI any ideas on the next steps?

Does anyone have any ideas with this? It seems that CentOs thinks there is a raid but in reality there is no raid.

Is there a way I can force it to NOT see an array?

Boot in rescue mode and try running dmraid -r -E /dev/sda and see if that helps. Please make sure there is no useful data on the disk before you try that!
