test builds on private server updates (mesa, kernel)

Hello Guys,

I really wanted to just update mesa. But the Linux kernel was also done quickly.

- Mesa 17.1.2 (remove sanitizy check, otherwise fail to built)
- Kernel 4.11.4

can be found at:

<a href="http://centos.cms4all.org/repo/7/kernel/" title="http://centos.cms4all.org/repo/7/kernel/">http://centos.cms4all.org/repo/7/kernel/</a>

<a href="http://centos.cms4all.org/repo/7/mesa/" title="http://centos.cms4all.org/repo/7/mesa/">http://centos.cms4all.org/repo/7/mesa/</a>

Unfortunately still no time found to care about winehq.
OK.

using autofs on C-7

Hi all!

I'm trying to set up autofs on my C7 netbook so I can automount a cifs
share (actually two) from my NAS box, and because when I'm not at home
I don't want it attempting to mount it.

so I've read several howtos on it, including the one on the CentOS Wiki.
but what I've got isn't working right, and I don't know why.

I'm trying to follow the "even-better method", but am finding I don't
understand the syntax of entries, so I'm flailing around trying different
things.

so, here's what I have now:

in /etc/auto.master:

/mnt/syno-fredex /etc/auto.syno-fredex

I added /etc/auto.syno-fredex

C7, systemd, say what?!

I just updated a system - as in minutes ago, and log back in after it
reboots, and this is in dmesg:
[ 88.202272] systemd-readahead[484]:
open(/var/tmp/dracut.fP4yj1/initramfs/usr/bin/loginctl) failed: Too many
levels of symbolic links
[ 88.202515] systemd-readahead[484]:
open(/var/tmp/dracut.fP4yj1/initramfs/usr/lib/systemd/system/dracut-emergency.service)
failed: Too many levels of symbolic links

Anyone know what this is - some weird bug, a garbage message?

Unable to map more than 4 workspaces to keyboard shortcuts on C7.

Hi,

I have a new install of c7 with the gnome desktop. I run it with 12 workspaces.
Normally I create the shortcuts so that ctrl+f1 maps to workspace 1 ctrl+f2
maps to f2, etc. When I goto applications -> settings -> keyboard -> shortcuts
-> navigation, I only have the ability to define "Switch to workspace" 1
through 4.

Domain Logout, then domain login again, profile corrupt -> replaced by TEMP profile

Hi

I have had this problem for a while, but waited to post this until I upgraded to see whether the upgrade would fix it.
I upgraded samba to the 4.2.X stream from 3.6.X stream, but it happens on both, 3.6.X and 4.2.10.

Whenever someone logs out, then in again the profile gets corrupted and a new TEMP profile is created (the dreadful "creating new desktop").

Crazy thought about upgrading to new major release

I have older systems out there that work fine, just for what ever reason
would be great to upgrade from a C5 -> C7 (due to no longer supported) or
C6 > C7 (for updated packages).

Sounds like the upgrade tool is not quite an option...
I was thinking...

What would be wrong with any "easy" script that did the following:

1) Removed all packages with the --justdb option.
2) Import the RPM-GPG-KEY-CentOS-7
3) install the centos-release-7.3.1611 ...

weird SELinux denial

I keep seeing this in my audit.logs:

type=AVC msg=audit(1496336600.230:6): avc: denied { name_connect } for pid=2411 comm="dbus-daemon" dest=111 scontext=system_u:system_r:system_dbusd_t:s0-s0:c0.c1023 tcontext=system_u:object_r:portmap_port_t:s0 tclass=tcp_socket

Was caused by:
The boolean allow_ypbind was set incorrectly.
Description:
Allow system to run with NIS

Allow access by executing:

The weirdness is that when I check allow_ypbind, it’s already on:

C7 ansible 2.3 become_method: su not working

I just don't know what else to try. I've beat my head on this for 3 days
now and it's becoming obvious that either Ansible 2.3 is a complete
disaster, or the CentOS 7 package is a complete cluster. Here's my
problem. I am working on getting an ansible server to manage about 100
or so CentOS 6 servers. All have an unprivileged user account setup (up
to 3 years before I got here in April) but that user account isn't setup
with sudo access. The way to get to root is 'su'.

I'm not a newbie with Ansible as I used it extensively in my previous
position to manage ~70 or so Ubuntu servers.

C6 or C7 for an old netbook

I've got an old HP Netbook, which is just fine for taking with when I'm
travelling, to check email and news. I have a very old Ubuntu
netbook-remix on it, and it really, *really* needs to be updated to
something current. I, of course, would prefer CentOS....

The question is: I see that *if* the specs I just looked up (I'm at work,
not home, where I could just turn it on, but they sound right) Atom N270
CPU, 2G RAM, 160GB drive - what should I put on it, C6 or C7?

CentOS 7 install: closest mirror not supported?

Hi,

Do CentOS 7 installs not automatically use a closest mirror for
installing like Fedora does, or is that due to the way I'm starting
the install (virt-install)?

Background:

I'm trying to find the best way to do installs using basic local media
(network install, but *without* the need to download the squashfs.img
for every install) but without a full local mirror.

MySQL on Centos 7 (armv7)

Dear Community

I am trying to install MySQL 5.6 on a Raspberry PI 3B.   Using my normal procedure by downloading the yum repo rpm and installing MySQL through that is not working.  There is no rpm information for arm7.

Can anyone please point me in a direction where I can find a procedure on how to install MySQL 5.6 on Centos 7 running on a PI3?

Kind Regards,

Leon

should NUMA be enabled?

Hi,

should NUMA be enabled in the BIOS of a server that has
two sockets but only a single CPU in one of the sockets?

From what I´ve been reading, it is unclear to me if NUMA
should be enabled only on systems with multiple CPUs in
multiple sockets or if multiple cores of a single CPU in
a single socket benefit from NUMA being enabled, and if
memory access in general benefits from NUMA being enabled
(in some other ways) even when there is only a single
CPU in a single socket.

It seems clear that NUMA should be enabled an can be taken
advantage of when there are multiple CPUs in multiple sock

kvm/qemu and CPU load

Hi,

I have a server using its 4 physical network interfaces
bonded, with the bonding interface added to a bridge. The
bridge has the IP, and three VMs are using the bridge. Two
of the VMs are running Debian, one is running Windoze 7.

CPU load caused by the qemu-kvm processes is way higher than
I´m happy with. One of the Debian machine causes around
22% while it´s basically idle, the other one is around 3%,
and the Windoze one is around 50. They are all mostly idle.

I can observe that when some network traffic is going on with
the Windoze machine, it causes a CPU load of 200%.

Possible bug in updating glibc?

Hey all, not sure if this was operator error or what.

I'm running a KVM host on updated CentOS 6. The guest is built from the
CentOS 6.9 dvd1 with just @base and @core package groups.

When I went to install mysql it failed due to incompatibilities with the
libcc versions. Updated just glibc and glibc-common and then installed
mysql. Shortly there after it started to freeze and lost connection.

The KVM host is fairly beefy and mysql wasn't doing anything but running
with no queries or data.

NFS mount on Centos 7 crashing

Upgrade 6 to 7

I found this site <a href="https://wiki.centos.org/TipsAndTricks/CentOSUpgradeTool" title="https://wiki.centos.org/TipsAndTricks/CentOSUpgradeTool">https://wiki.centos.org/TipsAndTricks/CentOSUpgradeTool</a>

Is this still the case - there is no upgrade path from 6 to 7 ?

I have a few remote servers I'd like to upgrade (if possible).

yum install <olderversion> does not downgrade

We're using ansible to configure our CentOS 6 servers, and we have a
task to install a specific version of a package:

- name: install thrift2
yum: name=ripencc-thrift2-{{ version }}

In this ansible task, the "version" variable is set by the operator.
When we want to upgrade, it works. But today we had to downgrade, and
noticed that ansible wasn't downgrading it.

CentOS 7 + KDE: Okular view PDF files OK but prints a blank page

Hi,

I recently installed CentOS 7 + KDE 4.14 on my main workstation, and
overall I'm very happy with it.

Okular seems to have trouble with some PDF files. I'm using the Dolibarr
application to generate invoices. I can view the resulting PDF file OK,
but when I try to print it, I get a blank page. A few days ago I had a
similar problem with a PDF file generated from a french administration
online form.

On my previous installation (Slackware64 14.1 + Xfce + Evince built from
source) I never had any trouble with PDF files.

Any suggestions?

Cheers,

CentOS 7, X issue

One of my users is reporting that he's working (heavy graphics, I
believe), and X freezes. So, to save him from rebooting, I did init 3. And
waited. Almost a minute and a half later, it had not completed. I quit,
killed X, and then could init 3, then init 5.

I'm not finding clues as to what hung.

Low random entropy

I am use to low random entropy on my arm boards, not an intel.

On my Lenovo x120e,

cat /proc/sys/kernel/random/entropy_avail

reports 3190 bits of entropy.

On my armv7 with Centos7 I would get 130 unless I installed rng-tools
and then I get ~1300. SSH into one and it drops back to 30! for a few
minutes. Sigh.

Anyway on my new Zotac nano ad12 with an AMD E-1800 duo core, I am
seeing 180.

I installed rng-tools and no change.

It doesn't. Got some errors. And then I remembered years back where
there was some extra options used to run startx on one of the other

But it has been too many years and I can't find any notes on it.

network setup: meaning of PEERROUTES option

Hi,

what´s the meaning of the PEERROUTES option in the networking
scripts? I couldn´t find that documented anywhere.

I managed to set up a bonding interface and when sending pings,
I´m getting redirection messages from the gateway unless I
manually add a route to the network. So I guess that for some
reason, the routing doesn´t get set up correctly, and I wonder
how to get that to work. Am I missing the PEERROUTES option,
or does that do something else?

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...

have to spoof the MAC address, due to a software license. Now, I've got
net.ifnames=0 biosdevname=0 on the grub2 command line, and I've got the
spoofed MAC address in /etc/sysconfig/network-sctipts/ifcfg-eth0.

But he had a serious problem - X froze, and he thought to reboot, rather
than call me. It came up with the actual MAC.

Best practices for copying lots of files machine-to-machine

An entire filesystem (~180g) needs to be copied from one local linux
machine to another. Since both systems are on the same local subnet,
there's no need for encryption.

I've done this sort of thing before a few times in the past in different
ways, but wanted to get input from others on what's worked best for them.

One consideration is that the source filesystem contains quite a few
hardlinks and symlinks and of course I want to preserve these, and
preserve all timestamps and ownerships and permissions as well.

C6 Module Keys

Hello,
As part of testing an alternative module I saved the original module and
copied the test one in.

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?
