systemd order help?
by James Pearson 12 Jun '17

12 Jun '17

I'm looking into 'porting' some custom init.d scripts that are in use on CentOS 6 boxes for use on CentOS 7 using systemd One particular init.d script needs to run after autofs has been started, but before X11 is started I'm guessing I could use something like: After=autofs.service Before=graphical.target Is this correct? However, I would like to use the same systemd unit file on servers that won't run X - will the above work? Or is there a better/another way of doing this? Thanks James Pearson

Unable to map more than 4 workspaces to keyboard shortcuts on C7.
by me＠tdiehl.org 12 Jun '17

12 Jun '17

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. There does not appear to be a way to map keyboard shortcuts for "Switch to workspace" 5-12. Does anyone know how I can add the ability to create shortcuts for workspaces 5-12? In previous versions (c-6 and older) the number of available keyboard shortcuts matched the available number of workspaces configured. I am thinking that there is some file someplace that I should be able to modify to make this work but so far I cannot find it. Regards, -- Tom me(a)tdiehl.org Spamtrap address me123(a)tdiehl.org

Wrote Yum Plugin - got a question about arguments
by Andreas Benzler 11 Jun '17

11 Jun '17

Hello Guys I have written a small yum plugin. My question: How can I convert the arguments to a string to output them inside a hook. I can use many programming languages, but unfortunately no python to understand the documentation properly. http://yum.baseurl.org/api/yum-3.2.26/yum.plugins.ArgsPluginConduit-cla ss.html def init_hook(conduit): conduit.info(2, 'Hello world') conduit.getArgs() InitPluginConduit instance has no attribute 'getArgs' No matter if i put it into pretrans_hook or posttrans_hook. This time i take " ".join(commands). Thanks Andy

Some file management functions in the right mouse are missing
by sunyeping 11 Jun '17

11 Jun '17

Dear all, I recently installed CENTOS7. I find that Some file management functions, such as creating new file, arranging file by size, arranging file by data, etc., in the right mouse are missing, and the item "creating new folder is present, but it is grey. These right mouse items are availabe in centos 6. How could they be added in Centos 7? Thanks in advances. Yeping Sun

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? mark

test builds on private server updates (mesa, kernel)
by Andreas Benzler 09 Jun '17

09 Jun '17

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: http://centos.cms4all.org/repo/7/kernel/ http://centos.cms4all.org/repo/7/mesa/ Unfortunately still no time found to care about winehq. OK. My daughter plays under the same driver stack in manjaro linux World of Warcraft for hours and my Fedora in the business also runs stable over several days without failures. https://copr.fedorainfracloud.org/coprs/andybe/ Good night.

using autofs on C-7
by Fred Smith 09 Jun '17

09 Jun '17

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: /mnt/syno-fredex -fstype=cifs,rw,credentials=/root/.smbcred,defaults,uid=fredex,gid=fredex,noauto,users,exec,vers=3.0 ://nasbox/home my goal is to mount //nasbox/home as /mnt/syno-fredex so I do systemctl restart autofs and it appears to restart (no messages appear). when I then do "ls /mnt/syno-fredex" it doesn't appear to actually get mounted, and /var/log/messages doesn't show anything. I'd appreciate advice on this matter. thanks in advance!

kvm/qemu and CPU load
by hw 08 Jun '17

08 Jun '17

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%. "Some network traffic" means that virt-top is showing 1M/2M RX/TX. Considering that the bonding interface is theoretically capable of handling 4Gbit full duplex, the 3Mbit are neglectable. Virtio drivers are being used. Currently, virt-top shows 1.9% CPU for the Windoze machine and top shows 22% CPU load for the corresponding qemu-kvm process. There is almost not network traffic. The VM has 4 CPUs assigned. What may cause the high CPU load? Something must be seriously wrong for an idle machine causing 22% CPU load and for the same machine, still basically idle, with a some network traffic to cause 200% CPU load on a Xeon 5690.
