Fedora – Ramdisk creation

In Fedora, ramdisks are not created by default as is the case with RHEL. So, if you need to get Ramdisks on Fedora, then you can do this:

sudo yum install MAKEDEV

This will create some default Ramdisk’s in the “/dev” directory. Now, if you need to change anything then feel free to go to “/etc/makedev.d” and feel free to change these files.

So, some of things that I am very used to since last couple of years, do not seem to work as expected and I need to keep verifying a lot of things on the server, very inconvinient to keep testing the script on the server (need to connect on VPN) just to test some very simple things.

Zabbix error\’d — just for fun

<img class="size-medium wp-image-2432" title="History-Zabbix Error'd" src="http://blog.amit-agarwal.co.in/wp-content/uploads/2010/08/History-Zabbix-300x151.jpg" alt="History-Zabbix Error'd" width="300" height="151" />

I was woking on Zabbix some days back and here&#8217;s a screenshot that I took from Zabbix running on <a class="zem_slink" title="Red Hat" rel="homepage" href="http://www.redhat.com">Red Hat Enterprise <a class="zem_slink" title="Linux" rel="homepage" href="http://www.kernel.org/">Linux 5. Pretty interesting to see that there is a graph with all the values on the <a class="zem_slink" title="Cartesian coordinate system" rel="wikipedia" href="http://en.wikipedia.org/wiki/Cartesian_coordinate_system">Y-axis as 3.26GB and still there is a trend on the graph. How many times did you get such graph 🙂
