My grub2-btrfs & yum-plugin-snapper
by Andreas Benzler 15 Jun '17

15 Jun '17

Hello Guys, Last Sunday I had the idea to expand my gameplay btrfs. Now what was missing was a yum plugin which worked like arch or opensuse. Ok, I told myself and learned a little python. Also something for grub2 to boot into a snapshot. My results are up on: https://copr.fedorainfracloud.org/coprs/andybe/Centos7Btrfs/ grub2-btrfs (do not use grub-btrfs, this is the version before) yum-plugin-snapper The grub2 plugin is tuned to snapper and is therefore in conflict with yum-plugin-fs-snapshot (from archlinux). /etc/yum/pluginconf.d/snapper.conf [main] enabled=1 verbose=0 configs= update_grub2=False If no configs specified so is tried to make a global snapshot. Of course, comma-separated configs can be saved. The yum-plugin-snapper has no direct dependency to yum-plugin-snapper (optional) There are many posts how it works for example: http://dustymabe.com/201 7/02/12/fedora-btrfssnapper-the-fedora-25-edition/ Here how it looks like: LANG=C yum remove htop Loaded plugins: fastestmirror, snapper Resolving Dependencies --> Running transaction check ---> Package htop.x86_64 0:2.0.2-1.el7 will be erased --> Finished Dependency Resolution Dependencies Resolved ======================================================================= ========= Package Arch Version Repository Size ======================================================================= ========= Removing: htop x86_64 2.0.2- 1.el7 @epel 207 k Transaction Summary ======================================================================= ========= Remove 1 Package Installed size: 207 k Is this ok [y/N]: y Downloading packages: Running transaction check Running transaction test Transaction test succeeded Running transaction Erasing : htop-2.0.2- 1.el7.x86_64 1/1 Verifying : htop-2.0.2- 1.el7.x86_64 1/1 Removed: htop.x86_64 0:2.0.2- 1.el7 Complete! LANG=C snapper list Type | # | Pre # | Date | User | Cleanup | Description | Userdata -------+---+-------+--------------------------+------+---------+------- ----------+--------- single | 0 | | | root | | current | pre | 1 | | Thu Jun 15 08:42:18 2017 | root | | yum remove htop | post | 2 | 1 | Thu Jun 15 08:42:19 2017 | root | number | | Grub Menu CentOS Linux (3.10-.......) CentOS Linux (0-rescue ....) CentOS Linux Snapshots Still a small note: here would be 6 entries for 2 kernel for each snapshot created. It can also cause the system to stop booting. This happened to me once grub.cfg 1.1MB was large, on fedora. If Grub2 is so installed that it looks for strange systems, a yum installation, because of grub2-mkconfig, also take a long time. It works as it is. The grub2 plugin needs a little bit work. But now analyse jet. I made ist failsafe for linux and linuxefi. For me, it was important to know whether such a thing under centos works, because yum-plugin-fs-snapshot is intended for several file systems. Can be helpful or not. Just something different for me. Fun work :-) Sincerely Andy

how to enforce sunit and swidth for root device/partition when installing?
by hw 13 Jun '17

13 Jun '17

Hi, how can I force the Centos 7 installer to use the particular sunit and swidth values that are matching the hardware raid device I´m installing on? The installer forces me to reformat the partition I want to install on :( It does not let me specify any options about creating the file system :( Even when I create the file system manually with correct values after telling the installer where to install and before beginning the installation, xfs_info shows different values for the file system than I used when I created it once I rebooted. So apparently the installer re-creates the file system again when I start the installation after it had me accept the changes it wants to make.

The distinction between "After/Before" and "Requires" is exactly for the reason you give; the ordering directives don't require anything, so without display-manager.service enabled, Before=display-manager.service is just a no-op. Actually, you might even want "BindsTo=autofs.service", which is stronger. Depending on your setup, you many want to look at converting your automatic mounts into systemd mounts, and depend on that directly, rather than on the autofs service. Just one little thing to note here that many don't realise. All mounts in the system (ie not manually via the mount command) are systemd mounts. There's a generator that makes mount units from fstab and it is the actual runtime mount unit that gets used. So with things in fstab you can still have a service require something like data.mount ... There's even a directive RequiresMountsFor to ensure that a path is mounted before that unit is started. Finally autofs is made even easier with systemd as all you need to do to declare a mount autofs is x-systemd.automount in the options field and then it'll only be mounted on demand rather than at boot.

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
