Wireless Nework and NDISwrapper on Ubuntu Intrepid
( Or how to make sure you buy a supported wireless card otherwise you are toast)
Well I decided to finally have a wireless network at home and do it on the cheap. I have an old PC lying around so I said to myself get a cheap wireless network card supported on Ubuntu and voila. Well it is not that easy specially when you buy the wrong card!
A HA Two-Node Server Side Cluster Using Glusterfs and CentOS
I came across Glusterfs the other day. On the surface it seemed similar to DRBD but after closer examination I did realize it was completely different. After some reading I came to realize it may offer benefits over DRDB and GNBD and it seemed extremely straight forward to implement so I decided to test a two-node cluster and run Apache on it.
Two-Node GNBD Redux
In a previous post I had a two-node cluster using gnbd on CentOS. While that setup worked fine it had a major draw back. It used manual fencing thus not a practical real life example. So I decided to test a better setup, since I am using virtual machines the way to do this was to use gnbd fencing and gfs.
