X86_64 Install Issues

Postby ByronDMoran » 2011/09/14 20:43:11

As a department we have just acquired a rather powerful machine to do our high density simulations. I was very excited to put a copy of CentOS on it and get it up and running. Unfortunately, I run through all six disks in the installation, it says it finished, and then immediately gives me a message saying "Fatal Exception Occurred" with a few trace backs to where the error was. The computer we just got has Intel Xeon 32 core processors, 64GB of DDR3 RAM, nVidia Quattro 4000 (I think) video card and a lot of hard drive space. The SSD is 250GB and is to be used as the primary boot and host the OS and programs. I cut that in half and put half for a swap partition (Am I still supposed to do half of my RAM as swap?). The two 2TB hard drives I RAID 1'd together to keep a place for secure data storage and the other 2TB hard drive I left as temporary or non-secure storage that will not be backed up. Do I need the X86_64 version of CentOS 5.6? Can I do the i386? I wasn't sure of the difference and the person I asked told me that I needed the X86_64 version due to how much RAM I had in the machine. I can't run CentOS 6 due to software incompatibilities.

It's overkill these days. On a system that size I'd probably make swap at 8GB on the basis that if you get 8GB into swap you'll start to notice it.

then immediately gives me a message saying "Fatal Exception Occurred"


You didn't check the box during the install to enable the CentOS Extras yum repository did you? That causes a crash at the end of the install. If not then the stack trace might tell someone something.

Thanks for the reply, I'll make sure to reformat the swap next time I reinstall. As for the yum repo option, I didn't see that it existed...I must have overlooked it. I was unable to get anaconda into a graphical install (It said it failed to load when I hit enter to do it that way) but each of the six disks passed when I tested the media via CentOS before the initial OS install and the md5sum matched on each. What else could be the problem? Not sure where to go from here I feel like I've covered my bases pretty well with checking everything.

Is there a particular reason to go with CentOS-5 rather than 6 for a fresh install? A reason to go with CD vs. DVD? For a number cruncher with large amounts of RAM you almost certainly want to consider x86_64 rather than i386 regardless of the release.

Apart from proven stability and a good track record vs something that appears to be slightly rough around the edges and is lacking many many updates from upstream?

Well, there are two very good EL6 alternatives that I can vouch for:

Code: Select all

$ lsb_release -sd
"Red Hat Enterprise Linux Server release 6.1 (Santiago)"

$ uname -rpmi
2.6.32-131.12.1.el6.x86_64 x86_64 x86_64 x86_64

and

Code: Select all

$ lsb_release -sd
"Scientific Linux release 6.1 (Carbon)"

$ uname -rpmi
2.6.32-131.12.1.el6.x86_64 x86_64 x86_64 x86_64

Both run pretty good for me. :-D

Definitively you need to run 64-bit version - 32-bit PAE supports up to 32G (if I remember correctly).

As for the crash - did you check your HW? Sometimes even New servers have HW defects.

It might be useful if you post details about your HW.
