How to create a single 4GB large ramdisk?
by Clemens Eisserer 18 Jun '14

18 Jun '14

Hi, I need a single ramdisk which is a real block device (unlike tmpfs), so I found the ramdisk_size kernel boot parameter. However, after invoking "MAKEDEV ram" I get hundreds of 16mb large ramdisks, instead of a single 4GB large: dd if=/dev/zero of=/dev/ram0 bs=1024k count=2048 dd: error writing ‘/dev/ram0’: No space left on device 17+0 records in 16+0 records out 16777216 bytes (17 MB) copied, 0.032487 s, 516 MB/s Any idea how to get a single ramdisk instead, I am using Fedora20 on x86_64 btw. Thank you in advance, Clemens

5tFTw: F21 on Track, FESCo Membership Change, More DNF vs. Yum, Reading VM Logs, and Wiki Infoboxes (2014-06-17)
by Matthew Miller 17 Jun '14

17 Jun '14

Reposted from <http://fedoramagazine.org/5tftw-2014-06-17/>. Fedora is a big project, and it’s hard to follow it all. This series highlights interesting happenings in five different areas every week. It isn’t comprehensive news coverage — just quick summaries with links to each. Here are the five things for June 17th, 2014: Fedora 21 Is Not Delayed ------------------------ It might seem a bit funny to report on something that’s *not* happening, but this got picked up by some of the tech press so I thought it best to clarify the actual situation. Short version: we’re *not* currently planning any delay from the established target of October 14th, 2014. Longer version: the Fedora Server Working Group is writing new code which will provide a programmatic interface (an API) for provisioning servers with certain Server Roles. This doesn’t compete with existing config management tools like Puppet, Chef, or Ansible — it provides a framework that they (or the new Cockpit web GUI) can talk to. That’s taking a little bit longer than planned, especially because new input from the CentOS Simple Linux Server SIG was incorporated. However, at last week’s meeting, FESCo (the Fedora Engineering Steering Committee, which manages the overall schedule) decided to allow *just* this Server Role Deployment Framework]framework] to land a little late in the Fedora Alpha schedule, but with no delay to the rest of the project or change to the overall F21 schedule. * http://fedoraproject.org/wiki/Server * http://fedoraserver-wgblog.rhcloud.com/primary-goals-for-fedora-server-in-f… * https://fedoraproject.org/wiki/Changes/FrameworkForServerRoleDeployment * http://cockpit-project.org/ * http://wiki.centos.org/SpecialInterestGroup/SLS * http://meetbot.fedoraproject.org/fedora-meeting/2014-06-11/fesco.2014-06-11… Bill Nottingham Steps Down From FESCo; Kyle McMartin Steps Up ------------------------------------------------------------- Long-time and almost omnipresent Fedora contributor Bill Nottingham has started a new day job at open source config-management company Ansible, and resigned his Fedora Engineering Steering Committee seat in order to be able to focus on that. Our election policy states that open seats are offered to previous runners-up, which means Kyle McMartin is our newest FESCo member (although not, by any means new to Fedora). Thank you Bill for years of work on Fedora in FESCo and elsewhere, and welcome Kyle! P.S. We use Ansible quite heavily in Fedora Infrastructure. Also: Former Fedora Project Leader Greg DeKoenigsberg is also joining Ansible, which already boasts quite the slate of former Red Hatters and Fedora contributors. I’m looking forward to further collaboration across our open source projects. * http://fedoraproject.org/wiki/User:Notting * https://twitter.com/ansible/status/478518891665432576 * http://fedoraproject.org/wiki/Development/SteeringCommittee/Nominations#Kyl… * http://www.slideshare.net/AdityaPatawari/ansible-33223245 * http://www.ansible.com/management-team DNF as Yum Replacement, Continued --------------------------------- Last week, I wrote about a proposal to replace Fedora’s Yum package manager with DNF. That proposal — targeting next year’s Fedora 22, _not_ Fedora 21 this fall — is now officially on the table for discussion. That discussion continues on the Fedora devel mailing list. Although there are several long threads, it looks like people are generally open to the idea and advantages of the new code, but there are differing opinions on whether DNF should keep that name or become “Yum 4” — or even take a new generic name like `package`. Feel free to join in, although please remember to be constructive and to follow the Fedora Project Code of Conduct (which, basically, boils down to “be excellent to each other”. * http://fedoramagazine.org/5tftw-2014-06-10/ * http://yum.baseurl.org/ * http://dnf.baseurl.org/ * https://fedorahosted.org/fesco/ticket/1312 * https://lists.fedoraproject.org/pipermail/devel/2014-June/thread.html * https://fedoraproject.org/code-of-conduct Coming Soon to libguestfs: Smart Log Reading -------------------------------------------- The systemd journal brings a lot of useful features, including structured log formats and reliable connection of messages to the services they came from. But, its binary log format can be less convenient when you’re not working *on* the system where the logs reside. This is often the case when using libguestfs, an almost-magically- powerful tool for working with virtual machine disk images. Developer Richard W.M. Jones blogs about a new feature: virt-log. This command automatically does the right thing with several different guest system log possibilities, including understanding the journald format, knowing that Debian-based systems use `/var/log/syslog` instead of our `/var/log/messages`, and in the future will even read the Microsoft Windows Event Log. * http://0pointer.de/blog/projects/journalctl.html * http://libguestfs.org/ * http://rwmj.wordpress.com/2014/06/14/new-in-libguestfs-virt-log/ Add an Infobox to Your Fedora Wiki User Page -------------------------------------------- Our wiki serves many purposes (maybe too many!), but one of the the most useful is providing simple autobiographical and contact information for contributors. A neat little thing I stumbled across this week is the Infobox template, defined and documented at <https://fedoraproject.org/wiki/Template:Infobox_user>. Follow these instructions and add the template to your page for a clean, consistent presentation of your Fedora-relevant details. As a bonus, display your Fedora Badges with `{{ #fedorabadges: fasname }}` * https://fedoraproject.org/wiki/Template:Infobox_user * https://badges.fedoraproject.org/ * http://fedoramagazine.org/wp-content/uploads/2014/06/badges.png * https://badges.fedoraproject.org/user/mattdm -- Matthew Miller <mattdm(a)fedoraproject.org> Fedora Project Leader

Error while updating system
by Someone 17 Jun '14

17 Jun '14

I ran "sudo yum update -y" a few days ago, as I often do, and I saw the following error: Error: Package: kmod-VirtualBox-3.14.6-200.fc20.x86_64-4.3.12-1.fc20.2.x86_64 (rpmfusion-free-updates) Requires: kernel-uname-r = 3.14.6-200.fc20.x86_64 Installed: kernel-3.14.4-200.fc20.x86_64 (@updates) kernel-uname-r = 3.14.4-200.fc20.x86_64 Installed: kernel-3.14.5-200.fc20.x86_64 (@updates) kernel-uname-r = 3.14.5-200.fc20.x86_64 Installed: kernel-3.14.7-200.fc20.x86_64 (@updates) kernel-uname-r = 3.14.7-200.fc20.x86_64 Available: kernel-3.11.10-301.fc20.x86_64 (fedora) kernel-uname-r = 3.11.10-301.fc20.x86_64 Available: kernel-debug-3.11.10-301.fc20.x86_64 (fedora) kernel-uname-r = 3.11.10-301.fc20.x86_64+debug Available: kernel-debug-3.14.7-200.fc20.x86_64 (updates) kernel-uname-r = 3.14.7-200.fc20.x86_64+debug You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles --nodigest So I ran "sudo yum update -y --skip-broken", as suggested, and the update completed without incident. Then I left my machine alone for a few days, and came back to it figuring that I should run another update, so I did, and I received the same error. Does this indicate that anything worrisome is wrong? And, regardless, is there anything I could do to rectify the issue so that I don't keep having to run yum update commands with the --skip-broken option? Thanks

problems with a high res display
by Dave Bremer 16 Jun '14

16 Jun '14

I have a Dell M4800 with a 3200x1800 display, an nVidia Quadro 2100M, and Fedora 20. It was working very well. But after installing updates today, the gnome display manager cannot start. Anyone know of a fix?

Wifi connection issues with Intel?
by Richard Shaw 16 Jun '14

16 Jun '14

I looked though the last update and nothing jumped out at me... Tried journalctl --this-boot and paged through it, nothing jumped out at me. I've also tried all 3 installed kernels with the same result: Flakey wireless When I bring up the connection details (which takes to many clicks/menus) I see connection speeds of 1, 18, 24, or 54Mbit but this is a n device and has connected reliably at 108Mbit before now and the AP is less than 20 feet away. Sometimes connections get stuck at "resolving host" and other times it works. Anyone seeing the same issue? Thanks, Richard

dnf v.s. yum
by Ed Greshko 16 Jun '14

16 Jun '14

OK.... I read FAQ..... http://akozumpl.github.io/dnf/user_faq.html#why-do-i-get-different-results-… And the one following it.... "Is it possible to force DNF to get the latest metadata on dnf upgrade?" Running KDE and the notifications in the systray showed there are 12 updates available. Figured I give dnf a try, which I've done from time to time, but it showed no packages to update. OK....so clean metadata for both yum and dnf.... ran both "yum check-update" and "dnf check-update". yum listed the 12 [root@meimei ~]# dnf check-update google-earth 74 kB/s | 4.8 kB 00:00 Fedora 20 - x86_64 - VirtualBox 38 kB/s | 44 kB 00:01 Fedora 20 - x86_64 2.2 MB/s | 36 MB 00:15 RPM Fusion for Fedora 20 - Free - Updates 241 kB/s | 346 kB 00:01 Adobe Systems Incorporated 2.7 kB/s | 1.8 kB 00:00 RPM Fusion for Fedora 20 - Nonfree - Updates 116 kB/s | 100 kB 00:00 RPM Fusion for Fedora 20 - Free 325 kB/s | 487 kB 00:01 Fedora 20 - x86_64 - Updates 2.0 MB/s | 23 MB 00:11 RPM Fusion for Fedora 20 - Nonfree 19 kB/s | 289 kB 00:15 [root@meimei ~]# -- Do not condemn the judgment of another because it differs from your own.
