Hello, I am thinking of doing a raid 5 on an ubuntu server 14.04 system with 3 x 3TB drives and have a few questions... 1. How would the system boot if one of the drives goes down? 2. Is the boot loader installed on each drive? 3. If I pulled out a drive and put in a new drive, would it auto-rebuild or do I need hardware raid for that feature? -Thanks

How does one reload the /etc/hosts (clear cache?) after adding a domain to 127.0.0.1

location: ubuntuforums.com - date: February 28, 2011
I often manually add a troublesome domain (e.g., advertisements, fake virus alerts, etc.) to my /etc/hosts file on Ubuntu 10.04 Lucid; but the effect isn't immediate. My hosts file is already fifteen thousand lines long (having combined all the hosts files I could find on the net, including the MVP one); but I still, almost daily, find a new irritant to add to my /etc/hosts file. My problem is I do not understand WHEN the /etc/hosts file is next read after a change. I've been rebooting to make sure the hosts is re-read; but there must be a simpler way. My question: - WHEN is the /etc/hosts file reconsidered in Ubuntu? - Is there a way to have the /etc/hosts file re-read sooner?
