LVM not activating on reboot
by Duncan Brown 05 Oct '17

05 Oct '17

Hi I've recently rebuilt my home server using centos 7, and transplanted over the main storage disks It's a 3 disk raid5, with an lvm storage group (vg03) on there Activating and mounting works fine: # vgscan Reading volume groups from cache. Found volume group "vg03" using metadata type lvm2 # vgchange -ay 1 logical volume(s) in volume group "vg03" now active # lvscan ACTIVE '/dev/vg03/storage' [<1.82 TiB] inherit I can then mount /dev/vg03/storage as expected However on a reboot, boot fails if I add that entry to fstab: 'Timed out waiting for device dev-mapper-vg03\x2dstorage.device' I then have to activate it again with vgchange. I'm guessing I'm going to need a grub option, or do something with dracut but I'm a bit stuck here Thanks Duncan

compile webkit
by Jerry Geis 02 Oct '17

02 Oct '17

I am trying to compile webkitgtk I downloaded the webkit source, extracted CMake Error at Source/cmake/OptionsGTK.cmake:12 (message): GCC 4.9.0 is required to build WebKitGTK+, use a newer GCC version or clang I downloaded 2.14.7 - just like CentOS 7.4 has, how can I be getting a GCC error ? My goal is to get the MediaSource package in webkit working. It seems to not be enabled. Is there a better way ? Thanks, Jerry

prevent users from fiddling with network?
by Valeri Galtsev 02 Oct '17

02 Oct '17

Dear Experts, "this is system from the hell!" Than was my first reaction when I realized that logged in with GUI (X11) user can turn off (and on) network interfaces. Without being in sudoers file. Wow, this is scary to see on workstations I manage centrally. Even though I did consider local user to be able to execute the command "shutdown" (which distinguished RedHat and CentOS from other Linux flavors: after all local user can yank power cord off the wall). Sorry about my little rant above. Could someone point me into right direction as to how do I disable the ability of (local, logged in through X11) users to fiddle with network interfaces. Even worse, they can create new profile and define for interfaces to behave differently... In the past I could just add USERCTL="no" into interface ifcfg-... file inside /etc/sysconfig/network-scripts which doesn't seen to have any effect on latest CentOS 7. What is my pilot error here? (Ignorant in new shiny extremely MS Windows like for _ignorant_ person - me - system). Thanks a lot for all your help!

MP4/H.264 codec for Firefox?
by Roman Kennke 02 Oct '17

02 Oct '17

Hello, I am trying to get MP4/H.264 playback in Firefox to work on my CentOS laptop (for vimeo). I installed the gstreamer plugins as described here: https://wiki.centos.org/TipsAndTricks/MultimediaOnCentOS7 (No, I did not install Flash, VLC and all the other stuff. I only want HTML5 MP4 playback..) I enabled the nux repos. I did install all available gstreamer plugins, i.e. -good -bad -ugly -ffmpeg etc. No success. Has anybody got mp4 playback working? Here's a test page: https://www.quirksmode.org/html5/tests/video.html Help would be appreciated! Best regards, Roman

Turning on httpd_graceful_shutdown you allow httpd_t domain connecting just to ports labeled as httpd_port_t. Turning on httpd_can_network_connect you allow httpd_t domain connecting to all ports from SELinux POV. Right now, we ship selinux-policy with httpd_graceful_shutdown turned on and httpd_can_network_connect turned off. But it's confusing for users because they have httpd_can_connect turned off but httpd_t domain can still connect co http_port_t ports becuase of httpd_gracefull_shudown. I hope it's more clear now. > Do I need to do anything in FreeIPA setup? > No if httpd_can_network_connect is enabled during FreeIPA setup, you don't need to change anything.

yum repo issue
by Stijn De Weirdt 30 Sep '17

30 Sep '17

hi all, i'm trying to understand an issue i'm having with a yum repo (it's a mirror of the c74 repo). there's an rpm in the repo (ibutils-libs in this case); but the client using this repo says it cannot find this rpm (i did yum info ibutils-libs --disablerepo=* --enablerepo=c74 to exclude all other repos). other rpms are ok to use, so nothing structural going wrong (i think) the repo sqlite.bz2 on the client (in /var/cache/yum/...) mentions the rpm (bunzip ...sqlite3.bz2; sqlite3 ...sqlite .dump |grep ibutils-libs), so i guess that one is ok. i downloaded the rpm from our repo and official mirror, same md5sum. the weird thing is that yum localinstall also fails: > [root@hyp101 tmp]# yum localinstall ibutils-libs-1.5.7-13.el7.x86_64.rpm > Loaded plugins: priorities, versionlock > Examining ibutils-libs-1.5.7-13.el7.x86_64.rpm: ibutils-libs-1.5.7-13.el7.x86_64 > Nothing to do > [root@hyp101 tmp]# rpm -q ibutils-libs > package ibutils-libs is not installed anyone any hints how to debug this or some clues what could be going wrong here. stijn

Strange problem with CentOS 7 and guest additions in VirtualBox
by Nicolas Kovacs 29 Sep '17

29 Sep '17

Hi, I'm having a very weird problem with CentOS as a VirtualBox guest. Let me explain it step by step. tl;dr: I can install VirtualBox Guest Additions and configure a fullscreen 1280x1024 graphical resolution on a full install, but not on a reduced install with a lightweight window manager. Here's what I did. 1. Install vanilla CentOS 7 with KDE. 2. Boot to reduced 1024x768 resolution. 3. Install gcc, make and kernel-devel. 4. Build VirtualBox Guest Additions. 5. Reboot to full 1280x1024 resolution. ==> perfect On a vanilla desktop installation, this works perfectly. Now here's my second attempt. 1. Install minimal CentOS 7. 2. Install X11: yum groupinstall "X Window System" 3. Install WindowMaker from Nux repo. 4. Launch WindowMaker (startx) to reduced 1024x768 resolution. 5. Install gcc, make and kernel-devel. 6. Build VirtualBox Guest Additions. 7. Reboot and still have a reduced 1024x768 resolution. ==> meh I made another attempt with Xfce instead of WindowMaker (yum autoremove WindowMaker && yum groupinstall Xfce), but with the same result. Any idea what's going on here?
