Re: [CentOS] Semi-OT: hardware: NVidia proprietary driver, C7.4

Hi, folks, Well, still more fun (for values of fun approaching zero): 1. Went to install CUDA 9.0... well, gee, there is *no* CUDA 9.0. Even though I installed the 9 repo, all that I get is 8. I've used their webform, and an waiting on a reply. 2. I remove all nvidia packages. 3. It appears that the kmod-nvidia is what I need; that's what nvidia-detect says. So I try to install... bzzt, thank you for playing. a: uname -a: 3.10.0-693.2.2.el7.x86_64 #1 SMP Tue Sep 12 22:26:13 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux b: Installing : kmod-nvidia-384.90-1.el7_4.elrepo.x86_64 1/2 Broadcast message from systemd-journald(a)lyon.cit.nih.gov (Wed 2017-09-27 11:43:12 EDT): dracut[32409]: /lib/modules/3.10.0-693.el7.x86_64//modules.dep is missing.

Hi, is there a way to set the I/O scheduler via a tuned profile? If so, can the scheduler be set for different disks individually?

yum update problem - dependancy problem
by Gary Stainburn 26 Sep '17

26 Sep '17

I'm sure this is a FAQ, and a simple answer is available, but I've not managed it yet. I've tried all of the RPM database tidy routines. I've tried uninstalling the libblueray1 library but the ever growning dependency tree was too big. For a while I've been updating using the command yum -y --skip-broken --exclude rpcbind update which I though t was working, but the list of rpm's not updated is ever growing so i need to find a solution. Here is the output from the yum update. I've remove the bulk of the output for brevity but I can include it if needed. Gary [root@lcomp5 ~]# yum -y update Loaded plugins: fastestmirror, langpacks Loading mirror speeds from cached hostfile * base: mirror.netweaver.uk * epel: mirrors.ukfast.co.uk * extras: mirror.netweaver.uk * nux-dextop: mirror.li.nux.ro * remi-safe: rpms.remirepo.net * rpmforge: ftp.nluug.nl * updates: repo.uk.bigstepcloud.com * webtatic: uk.repo.webtatic.com Resolving Dependencies --> Running transaction check ---> Package NetworkManager.x86_64 1:1.4.0-20.el7_3 will be obsoleted ---> Package NetworkManager.x86_64 1:1.4.0-20.el7_3 will be updated ---> Package NetworkManager.x86_64 1:1.8.0-9.el7 will be obsoleting ---> Package NetworkManager-adsl.x86_64 1:1.4.0-20.el7_3 will be updated [......] ---> Package xmlsec1.x86_64 0:1.2.20-7.el7_4 will be installed ---> Package xmlsec1-openssl.x86_64 0:1.2.20-7.el7_4 will be installed --> Running transaction check ---> Package grub2-pc-modules.noarch 1:2.02-0.64.el7.centos will be installed ---> Package libblkid.i686 0:2.23.2-43.el7 will be installed ---> Package webkitgtk4-plugin-process-gtk2.x86_64 0:2.14.7-2.el7 will be installed --> Processing Dependency: /usr/sbin/ldconfig for package: libbluray1-0.4.0-6.el7.x86_64 --> Finished Dependency Resolution Error: Package: libbluray1-0.4.0-6.el7.x86_64 (@atrpms) Requires: /usr/sbin/ldconfig Removing: glibc-2.17-157.el7_3.1.i686 (@updates) Not found Updated By: glibc-2.17-196.el7.i686 (base) Not found You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles --nodigest [root@lcomp5 ~]#

Re: [CentOS] yum update problem - dependancy problem
by James B. Byrne 26 Sep '17

You have a conflicting package installed from repository @atrpms. You need to remove that package and/or disable that repository to get past the dependency issue. 'Skip broken' is not going to handle this situation nor will any other set of yum options.

Today's Topics: 1. Announcing the release of Gluster 3.12 on CentOS Linux 7 x86_64 (Niels de Vos) ---------------------------------------------------------------------- Message: 1 Date: Tue, 26 Sep 2017 12:41:44 +0200 From: Niels de Vos <ndevos(a)redhat.com> To: centos-announce(a)centos.org Subject: [CentOS-announce] Announcing the release of Gluster 3.12 on CentOS Linux 7 x86_64 Message-ID: <20170922113231.GK4899(a)ndevos-x240.usersys.redhat.com> Content-Type: text/plain; charset="us-ascii" I am happy to announce the General Availability of Gluster 3.12 for CentOS 7 on x86_64. These packages are following the upstream Gluster Community releases, and will receive monthly bugfix updates. Gluster 3.12 is a Long-Term-Maintenance release, and will receive updates for approximately 18 months. The difference between Long-Term-Maintenance and Short-Term-Maintenance releases is explained on the Gluster release schedule page: https://www.gluster.org/community/release-schedule/ Users of CentOS 7 can now simply install Gluster 3.12 with only these two commands: # yum install centos-release-gluster # yum install glusterfs-server The centos-release-gluster package is delivered via CentOS Extras repos. This contains all the metadata and dependency information, needed to install Gluster 3.12. The actual package that will get installed is centos-release-gluster312. Users of the now End-Of-Life Short-Term-Maintenance Gluster 3.11 will automatically get the update to Gluster 3.12, whereas users of Gluster 3.10 can stay on that Long-Term-Maintenance release for an other six months. Users of Gluster 3.8 will need to manually upgrade by uninstalling the centos-release-gluster38 package, and replacing it with either the Gluster 3.12 or 3.10 version. Additional details about the upgrade process are linked in the announcement from the Gluster Community: http://lists.gluster.org/pipermail/announce/2017-September/000082.html We have a quickstart guide specifically built around the packages are available, it makes for a good introduction to Gluster and will help get you started in just a few simple steps, this quick start is available at https://wiki.centos.org/SpecialInterestGroup/Storage/gluster-Quickstart More details about the packages that the Gluster project provides in the Storage SIG is available in the documentation: https://wiki.centos.org/SpecialInterestGroup/Storage/Gluster The centos-release-gluster* repositories offer additional packages that enhance the usability of Gluster itself. Utilities and tools that were working with previous versions of Gluster are expected to stay working fine. If there are any problems, or requests for additional tools and applications to be provided, just send us an email with your suggestions. The current list of packages that is (planned to become) available can be found here: https://wiki.centos.org/SpecialInterestGroup/Storage/Gluster/Ecosystem-pkgs We welcome all feedback, comments and contributions. You can get in touch with the CentOS Storage SIG on the centos-devel mailing list (https://lists.centos.org ) and with the Gluster developer and user communities at https://www.gluster.org/mailman/listinfo , we are also available on irc at #gluster on irc.freenode.net, and on twitter at @gluster .

Notice: Check your tuned settings for a performance boost.
by Jim Perrin 26 Sep '17

26 Sep '17

Last week we noticed that the default scheduler isn't being set properly in CentOS 7. I haven't checked this for CentOS 6, but it might be worth exploring. The TL;DR is unless you're running CentOS 7 on a laptop or as a virtual guest, you should probably run 'tuned-adm profile throughput-performance' I wrote up the full details here -> http://jperrin.org/centos/boosting-centos-server-performance/ -- Jim Perrin The CentOS Project | http://www.centos.org twitter: @BitIntegrity | GPG Key: FA09AD77

26 Sep '17

Hello all, had an issue on with a virtualmachine on XenServer 7.0 yesterday. It is a Centos 7.4.1708 and in a OOM situation it just shut down. No kernel panic where I could see a message, but it just turned itself off. All I could see in the /var/log/messages was the following: ------------------------------------------------------------------------ Sep 24 03:11:08 hostname xe-daemon: Running CollectDisk ...

VNC into CentOS 7.4
by Jerry Geis 26 Sep '17

26 Sep '17

When I VNC into 7.4 everything is fine until I run vmplayer (VMware). The vmplayer runs but when I type on the console for vmplayer which is also running a centos image I get multiple key presses - sometimes. Its not everytime - but enough to be annoying. How do I take care of that ? Jerry
