2014-05-06 06:52:55 -0500 answered a question Is it possible to enable xattr on tmpfs

According to the mount(8) manpage, it doesn't look like tmpfs supports extended attributes. However, you might be able to emulate what you need using the context and related mount options, see the explanation of this option in the manpage (under FILESYSTEM INDEPENDENT MOUNT OPTIONS).

Note that you can also use the fedy tool to install the tor browser, which essentially automates the official steps and creates a "shortcut" for you in your desktop.

You can get fedy here:

2014-04-09 21:17:56 -0500 commented question Restore gnome interface

You may be able to get your networking working by using the NetworkManager CLI interface. See here for examples of using the nmcli command to manipulate existing or configure new connections.

Once you've got your networking working, you can try troubleshooting to recover your system. Note that there is really no harm in having multiple desktop environments installed, so you might like to try reinstalling all of the desktops you had installed, which at least was working for you.

2014-04-09 21:09:23 -0500 answered a question How can i convert free space into unallocated space?

The Fedora installer will be able to handle shrinking your Windows file systems to install itself for you. Boot the Fedora installation medium and on the Installation Summary screen, choose the Installation Destination item. Next, select your disk with the Windows 7 install on it and click Done. You'll be shown an "Installation Options" dialog, click the Reclaim Space button. On the "Reclaim Space" dialog that is shown, click on your Windows partition and then the Shrink button. Use the slider to adjust the amount of space occupied by Windows, which will free up space for Fedora to use.

The same warnings apply as per cobra's answer, ensure you have backups if the resizing fails for some reason.

Also, refer to Section 9.11., Storage and partitioning of the Installation Guide for more details about partitioning and reclaiming space used by other operating system installs.

2014-04-03 06:44:17 -0500 answered a question Where is "ondemand" governor?

It looks like you have a modern Intel CPU which automatically uses the intel_pstate kernel driver for scaling the CPU frequency and voltage. For this driver, the only two policies supported are performance and powersave. The traditional governor modules used by the acpi-cpufreq driver are not used by this driver.

Additionally, it looks like the cpupower tool is written solely for the acpi-cpufreq driver and so its output cannot be trusted when the intel_pstate driver is in use. I'd say the Fedora Power Management Guide needs to be updated too.

See this article for information about the original kernel patch introducing the driver. See also this Google+ discussion for reasons for using the intel_pstate driver over acpi-cpufreq.

Nice work! Just remember though when using cp:

  • If cp encounters an error, it'll bail out and you'll have to start the entire copy again. The rsync and dd methods outlined in the other answers do not have this limitation.
  • Make sure the old and new partitions have the same mount options (especially for the user_xattr and acl mount options, see man mount) to ensure that all acls and extended attributes each file may have are copied over.

As long as the new partition you have created is the same size or bigger than the existing F20 root partition, you can use dd to copy the partitions. Boot from either a live CD (any distribution will do) or boot into your Ubuntu install and make sure both the old and new partitions are not mounted. Then run a command like the following:

dd if=/dev/mapper/f20-lvm-root of=/dev/sdxn bs=4096 conv=notrunc,noerror,sync

Where /dev/mapper/f20-lvm-root is your Fedora 20 root partition and /dev/sdxn is the new partition you created. This will take a long time to run. Once it is finished, you should be able to mount the new partition and you should change the fstab file to reflect your new disk layout and also update the F20 entry in your grub configuration.

2014-03-14 18:06:45 -0500 commented answer Where can I find a list of "standard" rpm repositories?

Good point. We are assuming here that this is a vanilla install without any extra configuration that may have changed the repositories that were enabled during install.

2014-03-14 04:16:52 -0500 commented answer Job queueing system

I'd also recommend Torque with Maui which I've deployed in a previous job for a small 32 node blade-based cluster. I believe Maui can be customised to support both the kind of scheduling policies you've listed.

2014-03-13 06:37:23 -0500 answered a question Where can I find a list of "standard" rpm repositories?

Depending on what level of detail you want, you can list the repositories that are on a vanilla install with the yum repolist command. In a terminal type:

yum repolist

For more details add the -v option:

yum -v repolist

This information is also available in the .repo files in the /etc/yum.repos.d directory, though not presented as readable as the output of the yum command above.

2014-03-13 03:12:55 -0500 commented answer Which memory configuration for a linux VM in gnome boxes?

Again, I'd suggest you stick with the default amount of swap that the installation calculates for you. If you start running out of RAM in your VM and using lots of swap, just increase the amount of RAM given to your VM, that is one of the great features of virtualisation, the ability to instantly provision hardware upgrades ;)

You can also use create swap file on the filesystem if you need more swap later, see the instructions here:

https://docs.fedoraproject.org/en-US/Fedora/14/html/Storage_Administration_Guide/s2-swap-creating-file.html

Those instructions are still applicable in all modern Linux distributions.

2014-03-12 05:21:11 -0500 answered a question P2v physical machine to virtual

You might want to try using the virt-p2v utility found in the virt-v2v package. Take a look at the official documentation here.

Note however that Fedora 20 doesn't appear to be a officially supported target so your mileage may vary.

2014-03-12 05:09:05 -0500 answered a question Which memory configuration for a linux VM in gnome boxes?

The amount of memory you should allocate will largely depend on what you want to do with the VM. You can use the minimum requirements given by the distribution as a guide though. For example, the release notes for Fedora 20 state a recommended 1GB of RAM:

https://docs.fedoraproject.org/en-US/Fedora/20/html/Release_Notes/sect-Release_Notes-Welcome_to_Fedora_.html

However as noted, you can have less RAM, but you may not get adequate performance out of a default install in such a case. Unless you are only going to run a text console, I'd recommend allocating at least 512MB RAM. You may prefer to use a Fedora spin with a graphical interface that can be lighter on RAM usage like Xfce or LXDE, see the spins page here:

https://spins.fedoraproject.org/

Regarding the file system layout, it largely won't matter whether you use LVM or plain partitions if you are just playing around a bit. I'd recommend you stick with the default distro partition layout. You can of course experiment with different install options later.
