Unknown Error

I've a HP 8000 Elite SFF machine with Intel Core 2 Duo Quad and 16 GB
RAM. I wanted to create a LAB environment to try new things (like CentOS
7). I installed CentOS 6.10 64-bit with no problems and everything is
running fine.

I then went to Server World and followed the instructions to install
Desktop and Virtualization. The install went fine but I had errors when
I attempted to build my KVM virtual machines.

How Can I ...

I've got a WD My Passport Ultra 1TB (USB) plugged into my router and I
have 4 Windows machines, all running Windows 7, and all 4 machines can
see the device as drive 'Y'. I use this device several ways, i.e. all my
Windows machines use the same Firefox bookmarks and cookies

I've got 5 machines running CentOS 6 x86_64 and I'd like to know what do
I have to do for them to 'see' that same 1TB device? Right now I use
winscp to get the data from CentOS and save it on the device via Windows.

Migrating From CentOS-6 To CentOS-7

I asked this in Vol 154, Issue 29:

I've a system that has been running CentOS 6 64-bit for almost
4-years and I want to start the move to CentOS 7 64-bit.

I run software RAID-1 with LVM everywhere except /boot which is a
standard partition RAID-1.

There are 2 areas that concern me greatly about this migration:

1. How do I duplicate my current grub configuration file that
supports a failure of /dev/sda to grub2?

2. How do I install CentOS 7 but use my existing hard drive layout
so I only format specific OS file systems.

Migrating From CentOS-6 To CentOS-7

I've a system that has been running CentOS 6 64-bit for almost 4-years
and I want to start the move to CentOS 7 64-bit.

I run software RAID-1 with LVM everywhere except /boot which is a
standard partition RAID-1.  There are 2 areas that concern me greatly
about this migration:

1.  How do I duplicate my current grub configuration file that supports
a failure of /dev/sda to grub2?

2.  How do I install CentOS 7 but use my existing hard drive layout so I
only format specific OS file systems.  My drive layout goes back to the
original proposed FHS layout.  The separate partitions are:

/bo

grub To grub2 Migration

I'm trying to move to CentOS 7.  One of my concerns is how to make the
changes to grub that supports booting from either of the disk partitions
that make up /dev/md0 (/dev/sda1 and /dev/sdb1) or whatever it would be
under CentOS 7.

Is there some document or tutorial available on making the move from
CentOS 6 to CentOS 7?

Kernel 4.12 and nVidia Driver

I tried to move to the latest stable kernel (4.12) so I could take
advantage of my newest custom system (Intel Core I7 6-core; 64 GB RAM;
MSI nVidia graphics card; 2 - 120 GB SSD; 2 - 4TB WD Black) on a UEFI
Asrock mother board.

I've had the machine for 3-months but I couldn't get it to work until I
found out that the Nouveau driver was causing me all the 'hardware'
issues.

Re: [CentOS] What's Next

I read somewhere that the PCIe issue is indicative of some other
hardware (PCIe SSD; etc) not working correctly.
Also, the 4.10 kernel is not the kernel out of the box. In a
environment with 10 or more servers do you really want a custom kernel?
How do you maintain all of these custom kernels (i.e. is a different
kernel required for a HP Gen 8 server different than a HP Gen 9
server?)? I've learned my lesson from using the FOSS HPLIP HP printer
driver - every time the kernel is updated you have to re-install the
driver...
TIA

What's Next

OK, AMD has announced it's new line of server and desktop processors.
What level of CentOS has been tested on them? OK then, when will CentOS
be tested on them? Or do we wait for Red Hat?

Latest AMD CPUs and AM4 Motherboards

Has anyone used the new AMD CPUs and AM4 motherboards with CentOS 6 / 7?

Any reservations or warnings?

DRM EDID Error

I'm running the following hardware:

MSI 890FXA-GD70 motherboard
With a AMI v1.7 BIOS
AMD Phenom II X6 (1055T)
8 GB RAM (2 x 4 GB DIMM)
nVidia Geforce 7300 (G72) video Card
ViewSonic VA2431wvm monitor
Plus

The OS is:

CentOS release 6.3 (Final)
2.6.32-279.5.2.el6.centos.plus.x86_64

Actually, on this machine I'm getting the following error during bootup:

[drm:drm_edid_block_valid} *ERROR* EDID checksum is invalid,
remainder is (222; 122; 251; but mostly 128)

From time to time the video locks up and sometimes goes black.

Re: [CentOS] 75% - 80% Rebuild Complete

OK, I'm about 90% sure that I've corrected the boot loader situation
with RAID-1 and the second hard drive.

Where Did All The Noise Go?

OK, I've got 2 machines running CentOS. One running CentOS x86_64 6.2
and the other running CentOS x86_64 5.8. At some upgrade point I've
lost all sound using Firefox and Thunderbird with my Gnome desktop.
When I bring up 'System', 'Preferences', 'Sound' and go to the
hardware tab and test the speakers, they are working.

Any ideas on how to get the sound back?

TIA,
Gene

HP Network Printer Issue - Resend

I sent the following message back in June, but I must have missed the reply:

I'm attempting to install and configure HPLIP (HP Linux Imaging and
Printing) software on my CentOS 5.3 x86_64 system without success. I've
got a HP Officejet Pro 8500 multi-function printer connected via
ethernet.
I'm getting a message saying that it cannot locate the libcups
module in
the /usr/lib64 and /usr/lib directories. However, I can locate then
correct modules using the find command.

Missing Hardware

I'm running Fedora 9 on a custom AMD Phenom Quad-Core with 8GB RAM
installed, 2-SATA hard drives (Seagate 500GB and Seagate 1TB); HP DVD/CD
RW Dual Layer with Lightscribe.
Lo and behold, I've updated my running (this machine) from kernel
2.6.25-14 to kernel 2.6.27.19-78.2.30 (?) and have experienced the
following:

Upgrade Caused Downgrade

All,

I've just experienced one of the most unnerving situations.
