Kernel crash
by Diego Farias 13 Oct '17

13 Oct '17

Hi everyone, I updated the kernel from 3.10.0-514.16.1.el7.x86_64 to 3.10.0-693.2.2.el7.x86_64 . While I was following these steps https://wiki.centos.org/HowTos/Laptops/Wireless/Broadcom (I knew that I needed to compile again everything) in order to activate WIFI, the laptop crashed doing # depmod -a # modprobe wl Noting that I replaced (naively) # depmod $(uname -r) from the guide (stupid mistake, I use tcsh and the command above didn't work; that's why the replacement). After the crash, I had to manually shutdown the laptop. Then, I booted the same kernel and it went to 'emergency mode'; as I don't have the root password (second stupid mistake; I'm superuser but I don't remember the root password/nor I can change it -I don't know-) I couldn't do a thing. Then, I booted the previous kernel, 3.10.0-514.16.1.el7.x86_64 (which works fine), removed 3.10.0-693.2.2.el7.x86_64 (yum remove), and reinstalling it from zero. Oddly, when I boot with the new kernel, the laptop crashes before login; the caps lock light tilts and nothing happens. I've done this several times and the same. I know I can use the older kernels to work, but I really want to fix this if possible. Thanks in advance.

nfsvers and nfs-utils-1.3.0-0.48.el7
by Paul Heinlein 12 Oct '17

12 Oct '17

We encountered a weird problem today, and I thought some of you might like to hear the solution. The underlying change was listed in the 7.4 changelog, so it's not a bug, but it may drive you buggy. The majority of our HPC cluster nodes run CentOS 7, though the exact patch levels vary from node to node. None is older than 7.3, but a few newer nodes were kickstarted right to 7.4. The problem was that our mounts of Isilon NFS exports were failing randomly among the nodes. Routing was fine. Network connectivity was fine. The short answer is that the default in 7.4, and I think in the nfs-utils-1.3.0-0.48.el7 package in particular, has changed. While NFS v4.0 was the default up to 7.3, the 7.4 protocols are subtly different: 1. Try NFS v4.1 first 2. Fail down to NFS v3 3. Fail down to NFS v2 The problem is that our Isilon works with NFS v4.0, not 4.1, but 4.0 is not in the fail-down path. The short-term answer is to specify nfsvers=4.0 in our autofs configuration files, which works like a charm. Like I said, this was an announced change, but the implications escaped us until now. So this little writeup is just for the record. -- Paul Heinlein heinlein(a)madboa.com 45°38' N, 122°6' W

yum-cron hourly errors
by John Ratliff 12 Oct '17

12 Oct '17

I receive messages like this from cron often. Not every hour, and not consistently between the servers running CentOS, but at least two per day. Is this normal? /etc/cron.hourly/0yum-hourly.cron: Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock error was 14: HTTP Error 403 - Forbidden Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=extras&infra=stock error was 14: HTTP Error 403 - Forbidden Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=updates&infra=stock error was 14: HTTP Error 403 - Forbidden

I do not love thee, kernel-3.10.0-693.2.2.el7.x86_64
by m.roth＠5-cent.us 12 Oct '17

12 Oct '17

I've been having a lot of issues with video, for example. However, this one... I have a user with a Dell R730. I install kernel and kernel devel, and the rest of the full update, and rebooted. Nope. 100% kernel panic, right around the time it switches root. I even rebuilt the initramfs, nope. And speaking of kernel panics, has *anyone* ever considered that all the data dumped to the console during one results in NOT BEING ABLE TO READ ANYTHING BUT THE LAST 24 or less, mostly less, lines? mark, frustrated, removed that kernel

Flame war police
by Andrew Holway 11 Oct '17

11 Oct '17

Hiya everyone, Is there a way to disable a thread that has degenerated into flaming? The recent "discussion" on /var/run descended into some quite nasty places and perhaps a lid should have been put on it. This seems to happen every few weeks and is somewhat embarrassing when I'm trying to persuade people of the "active and friendly Centos community" It was a shame that no one actually read past the belligerence his original post enough to come up with a solution. It was quite clearly a problem with third party packages not coming with SELinux policies. Cheers, Andrew

Location of grub.conf etc. with UEFI boot (CentOS 6)
by Toralf Lund 11 Oct '17

11 Oct '17

Hi, What's the proper/normal way of setting up GRUB for a CentOS 6 installation that boots using UEFI? I've recently set up such a system, but for technical reasons I mentioned in an earlier post, I booted in "legacy" mode during installation, which meant I didn't get the correct UEFI boot configuration, and had to set it up subsequently "by hand". I've managed to get the system to start up, but I had to place grub.conf under "/EFI/redhat/" on the EFI partition; without it, the system only boots into the grub shell. Is this normal, or is GRUB supposed to be able to find grub.conf under /boot? If not, how are updates on kernel upgrade etc. supposed to get done? Do I need a symlink from /boot/grub/grub.conf to the EFI parition? And will grub-install help with some of this? I haven't dared to try it, as I'm afraid it may break everything because it assumes an "MBR" configuration, or something. Also, how is /boot supposed to be set up anyway? Will it still normally be configured as a separate partition? Yeah, I know, I could re-install in UEFI mode (as I think I know how now), but I'm hoping you will save me from the effort. I also have a workable system anyhow, but kernel upgrades could be an issue, and it's nice to know the "right" way of setting up. Thanks, -Toralf

How can I disable at-spi-bus-launcher
by Frank Cox 11 Oct '17

11 Oct '17

I have a laptop that hangs up on shutdown saying that at-spi-bus-launcher is still running. Since I have no use for at-spi-bus-launcher anyway, I would like to get rid of it, but attempting to remove the at-spi2-core rpm wants to remove 99% of my desktop as well. The only way that I can see to get rid of it is to make /usr/libexec/at-spi-bus-launcher non-executable, but that's a pretty horrible hack. Can I permanently disable it without resorting to that? -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com

yum security update issue
by Thomas Roth 10 Oct '17

10 Oct '17

Hi all, I have used http://cefs.steve-meier.de/ plus https://github.com/vmfarms/generate_updateinfo to insert some security-information into my os-updates - mirror. This seems to work, but only partially. On my 7.4 test server, > yum --security -v check-update gives me dnsmasq, nss, nss-sysinit and nss-tools as the packages to install. The nss-packages are all of "severity = Important" But there are more of this type of packages, e.g. emacs. The centos-announce mails as well as the errata of Steve Meier as well as the generated updateinfo.xml all contain "CESA-2017:2771 Important CentOS 7 emacs Security Update" Just like the mentioned nss-packages, emacs is also labeled "severity = Important". But yum doesn't like it ;-( The output of > yum --security -v check-update tells me more, of course: --> 1:emacs-24.3-20.el7_4.x86_64 from os-updates excluded (updateinfo) Neither dnsmasq nor the nss-packages are listed, in particular not as excluded -? And at the end it says > Nothing matches emacs.x86_64 1:24.3-20.el7_4 from update Btw, "yum info emacs" lists the installed and wanted emacs versions correctly. What did I miss? Regards, Thomas
