Are you using a proxy somehow? Do you have proxy environment variables set
in your shell environment which may not exist in the ansible environment?


Thanks for the suggestion!

In the end it turned out the ansible version (2.7.7) on the that machine I run 
ansible from is not handling dnf commands correctly.
Once ansible was updated to 2.9.15 on the ansible master, it works fine.

[CentOS] dnf via ansible fails if baseurl is used on CentOS 8

[Thomas Eriksson]

Hi,


I ran into an odd issue on CentOS 8, anyone seen this?


When repos are configured to use baseurl instead of mirrorlist, the ansible dnf 
module fails.

It is as if it is ignoring the baseurl configuration.


#mirrorlist=http://mirrorlist.centos.org/?release=$releasever=$basearch=BaseOS=$infra
baseurl=http://my.local.repo.server/$contentdir/$releasever/BaseOS/$basearch/os/


If trying to use the dnf module in ansible, dnf is still trying to find a 
mirror to use and fails.

ansible  test-build-0  -m dnf  -a "name=zsh state=present"
test-build-0 | FAILED! => {
"changed": false,

"msg": "Failed to download metadata for repo 'BaseOS': Cannot download 
repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried",

"rc": 1,
"results": []
}

Using dnf locally from the command line works fine with baseurl


If I re-configure with repos using mirrorlist again, ansible dnf works as 
expected.

Just looking for ideas...

Just to put the record straight; it's not related to kernel debugging
being enabled or not. It's systemd debugging that is being turned on
for all menu entries, kernel debug or not.

Anyway, I think I have found a pattern. Only those machines that were
updated from 7.2 to 7.3 using the CR repo are showing this behaviour.
New 7.3 installs are fine. I'll just clean up the machines affected
and move on. There must have been some debug config left in an
installation script in one of the CR rpms.

thanks to everyone responding,

[CentOS] Systemd debug logging turned on in CentOS 7

[Thomas Eriksson]

Hi,

I noticed that some, but not all, of my CentOS 7 machines have these
kernel parameters for turning on systemd debug level logging added to
the grub.cfg file.

  systemd.log_level=debug systemd.log_target=kmsg

The parameters are *not* in the /etc/default/grub file, so if I rebuild
grub.cfg with grub2-mkconfig, they disappear.

I am a bit puzzled over how they got introduced.
Has anyone else seen this?

thanks,

Thomas

I haven't looked at how curl is built, butit is likely that the build
links against some other package that is, in turn, built against
OpenSSL.

You would not need the openssl-devel package to do that, only the
runtime libraries.

It looks like that package could be libssh2...

Tim,

First, logrotate only checks the state of the logfiles once a day, so
if your log grows to 8GB in a day, it has no chance to do anything
about it.

Second, elasticsearch is using log4j to control its logs. It has its
own naming and rotation rules and should not need to involve logrotate
at all. See /etc/elasticsearch/logging.yml

Third, if you generate that much logging in a day, maybe lowering the
loglevel, or perhaps there is a problem that should be fixed.

There is yet another issue with nvidia drivers and indirect GLX, which
will generate almost the same error message. Indirect GLX was disabled
by default in Xorg 1.17, which was introduced in Centos 7.2 and 6.8.

This problem only happens if you run the GL application remotely and
display on nvidia driver enabled screen. It's not clear from the OP
if that is the case here.

The solution would be to add +iglx to Xorg command line, but gdm is
hardcoding the Xorg parameters, so if you use gdm/gnome you are out
of luck.

 If this is CentOS 7 then you may need to put the ulimit directives in the 
 service file. 

 An example is I needed to increase the NOFILE limit for nfs-secure on a 
 Fedora 20 machine so I set 

 LimitNOFILE=16384 

 In /etc/systemd/system/nfs-secure.service 



Jason is probably on the right track here.

If it's centos 6 stick 'ulimit -s' in the init script
If it's centos 7 use LimitSTACK= in the service file

 Katello is just one piece. Satellite 6 also integrates Candlepin, Puppet

 Satellite 6 as one piece - is going to get a new upstream project.

The Katello project is the whole thing. During installation it pulls in

 Yep, just yank it.  It should start auto rebuilding on the spare.

 If you didn't have a spare you would pull the suspect drive and replace it
 with one of equal or greater capacity and it would auto rebuild as well.

 I have a bunch of them at home and have been using them at work for years.
 
 Thanks for your quick reply, Jason. I'm used to LSI/MegaRAID/PERCs, where
 you have to fail it, first. Oddity: I had the drive out for more then five
 minutes while getting it out of the sled, putting the new one in, oh, and
 dusting out the slot (gotta do that for all of them, next maintenance
 window), but after I put in the replacement, and used hpacucli to check,
 to my surprise it was rebuilding with the replacement, *not* with the
 spare.
 

HP's raid controllers appears to have some logic that if the rebuild to
spare disk have not yet reached 50% when you insert the replacement, it
will abandon the rebuild to the spare and rebuild to the replacement
instead.

I don't have any documentation to prove it, but I have observed it
numerous of times.

 You should look into the yum priorities option to ensure packages from

 It usually happens when I've wanted to change versions of the same

 Usually audio-visual software. Yum install triggers a conflict and yum
 uninstall on the older package cascades a bunch of undesirable

 If you have a better solution, let me know.

If the new package fulfills all requirements as the old one, you can use

Hi Lazlo,

To build almost any src.rpm package you will need some *-devel packages
installed. And if you are going to modify a build you need to install
the src.rpm into a build area first.

http://wiki.centos.org/HowTos/SetupRpmBuildEnvironment
https://fedoraproject.org/wiki/Mock?rd=Subprojects/Mock

The spec file contains a set BuildRequires statements that will be a
starting point. The clutter.spec file contains these:

BuildRequires: glib2-devel mesa-libGL-devel pkgconfig pango-devel
BuildRequires: cairo-gobject-devel gdk-pixbuf2-devel atk-devel
BuildRequires: cogl-devel = %{cogl_version}
BuildRequires: gobject-introspection-devel = 0.9.6
BuildRequires: gtk3-devel
BuildRequires: json-glib-devel = 0.12.0
BuildRequires: libXcomposite-devel
BuildRequires: libXdamage-devel
BuildRequires: libXi-devel

 Hi Guys,
 
 I'm facing this issue: https://bugs.centos.org/view.php?id=8482
 
 It came after upgrading to 7.1 and only Firefox is affected, Chrome is
 working.
 
 What I've tried so far:
 
 - Tried NVIDIA drivers 340.65, 346.59 and 346.72
 - Upgraded Firefox to 38
 - Tried Safe more / Refresh Firefox
 - Tried to turn HW accel. off in Firefox
 
 None of these has helped to eliminate the issue.
 
 Do you know how to work this around?
 
 Many thanks,

It sounds like you are experiencing this problem
https://bugzilla.gnome.org/show_bug.cgi?id=724788

The fix is a two line patch that is released against clutter 1.16,
but it applies cleanly against 1.14 (which is in CentOS 7, maybe this
gets fixed with the upcoming Gnome rebase).

I rebuilt the clutter rpms with the patch and the flickering problem
went away.

 I want to run the '/usr/bin/squid-analyzer' script once a day. I took a
 peek in /etc/cron.daily, and the package already installed an
 /etc/cron.daily/0squidanalyzer script.
 
 I wanted to know at what time CentOS ran the cron.daily scripts, so I
 typed crontab -l, but there was only no cronjobs defined for root.
 
 Here's how things look on a public Slackware64 14.0 server I administrate:

In CentOS 5 this is configured in /etc/crontab

From CentOS 6 onward, cron.hourly comes out of /etc/cron.d/0hourly
and the rest are configured in /etc/anacrontab

Yum is blissfully unaware of how the hostname is resolved. It just uses
a system call and expects to get an answer within a reasonable time.

The message do_ypcall: clnt_call: RPC: Timed out is coming from ypbind
and indicates that NIS is not working as it should.

Swapping the order of dns and nis in nsswitch.conf will probably get you
going for this particular case, provided that dns is working. But
the NIS problem is going to bite you sooner or later if you don't sort

Centos 7 runs systemd ,so
may need to use 'systemctl reboot' to reboot and 'systemctl
 poweroff' to shutdown system.
 I suggest to read systemctl manpage ( towards the end)

I think the shutdown command on CentOS 7 already reflects that.

# ls -l /usr/sbin/shutdown
lrwxrwxrwx. 1 root root 16 Oct 23 16:52 /usr/sbin/shutdown -
../bin/systemctl
# ls -l /usr/sbin/reboot

 Hi,
 
 Does anyone know if there is a clean way to downgrade to the old rpm 
 package when it was previously replaced by another that obsolete it?
 
 I mean, say that I have installed some rpm A-1.0-1.x86_64.rpm, and 
 along comes B-1.0-1.x86_64.rpm, whose spec has
 
 Obsoletes: A
 
 Now, if I do rpm -U B-1.0-1.x86_64.rpm or yum install 
 B-1.0-1.x86_64.rpm or (if B is available through an enabled repository) 
 yum update, what happens is that A gets removed and B is installed 
 in its place. Then I decide I want to switch back to A. So what do I 
 do? I know that one answer is
 
 rpm -e B
 rpm -U A-1.0-1.x86_64.rpm
 
 - but what if A and B provide facilities required by other installed 
 packages? I'll then have to pass --nodeps when removing B, but that's 
 something that I really want to avoid as it means loosing control over 
 whether all dependencies are satisfied. So is there an alternative?
 
 rpm -U A-1.0-1.x86_64.rpm alone seems to fail with file conflicts, 
 assuming B replaces some of A's files. In a real scenario I tried, 
 there was no mention of the fact that something that was essentially a 
 newer version of the same package, was already installed.
 
 yum upgrade A (when the package is available on a repository) fails in 
 a similar manner.
 
 yum localinstall A-1.0-1.x86_64.rpm is a bit smarter - it exists with 
 a message like Cannot install package A. It is obsoleted by installed 
 package B.
 
 yum downgrade A (via repository) says something like No Match for 
 available package: A-1.0-1.x86_64.rpm.
 
 yum localdowngrade A-1.0-1.x86_64.rpm would seem to have the highest 
 probability of success based on the above, except that there is no such 
 command :-/
 
 Any other ideas?

You can try using 'yum shell'

# yum shell
 remove B
 install A

 I'm running CentOS7 in VirtualBox 3.4.12 on RHEL6.5 without

 Hmmm.  I have windows 8.1, linux mint vm's on my centos 6.5 box and
 they all work with networking, but centos 7 vm doesn't have any
 networking.  Do I need to install the VM tools for the network to
 work.  I don't remember having to do that.  In cents 7 vm's, I don't
 get the nat'd IP address that is usually there :(

Didn't install anything extra, just chose the Gnome Desktop
installation and everything works as expected. Network is NAT.

 find 331 finds lots of things, but none of them is 331.49.

You updated the NVIDIA driver/kernel module  while the old one was
loaded into the kernel.

As root:
# telinit 3
# rmmod nvidia

 You just top posted, again. #0: fuck Outlook, and anything like it.
 FOLLOW, or intercollate, with the responses to your email. Follow, as in
 put your response AT THE BOTTOM, of the email, not the top.
 
 Just the way I'm responding to the email, above. Think of it as a
 conversation - you know what someone's said, *before* you respond. Top
 posting means I have no idea what you're responding to - you're not
 talking to someone in person And for anyone coming into an email
 thread late... I, and I think most folks, have *zero* intention of going
 to the bottom of an email which contains everything said in the thread,
 esp. with nothing edited out, and reading down a message, then paging up
 to read the response, then paging up *again* to read the next response.
 
 That's a M$ asinine introduction, and I despise it, since it makes it
 incredibly difficult to follow what's going on.
 
 I dunno, though - just dd'ing in the driver isn't going to work, if you
 mean that you dd'd the driver itself in, or was there an .rpm? If the
 latter, you need to find out what it does when it installs - where the
 actual driver's supposed to go, in what subdirectory, and then, of course,
 the last step would be to insmod it, and *then* rebuild the initrd so that
 it's included on boot.

Google for anaconda driverdisk, and you will find many write-ups on
howto supply drivers during installation.

Re: [CentOS] CentOS 6.5 install

[Thomas Eriksson]

That is a software RAID controller, only works if you install HP's
driver first. Or switch to AHCI mode for individual disks.

See this article https://access.redhat.com/site/articles/118133

   I just looked.  (For that matter, the actual PCI slots don't have 
 their numbers documented in the manual, either.)
 
 If you can't get lucky with Google, you're just going to have to install 
 EL7 on it and find out.  And if you can do that, why not just build it 
 and ship it?
 

On top of that, it seems to be only populated slots.

I added a USB3 PCIe card to my Gigabyte MB and the previous 'enp2s0'
became 'enp3s0'!

With the difference being that while RHEL/Centos have bugs and security

 This is yet another reason to use ELRepo's kmod-nvidia [1]. :-)  The
 major reason is that ELRepo's kmods are kABI-tracking, meaning no need
 to reinstall the driver upon kernel updates.

 Errr, this was not a kernel update and elrepo kmod-nvidia is installed.
 
 Cheers,
 B.J.

The libglx.so.325.15 file comes from the nvidia-x11-drv package, not the
kmod-nvidia.

Elrepo is not putting any symlink in /usr/lib64/xorg/modules/extensions
only in /usr/lib64/xorg/modules/extensions/nvidia

It then adds /usr/lib64/xorg/modules/extensions/nvidia to the
ModulePath in xorg.conf so the Xserver picks up the nvidia version of
libglx.so before the Xorg version. That way you

If you do have/had a symlink in /usr/lib64/xorg/modules/extensions, it's
a remnant from NVIDIA's own distribution, IIRC. It is the
xorg-x11-server-Xorg package that writes over that symlink.
