Ages ago (it seems) I posted a howto on configure NFS using Puppet and Hiera. I have been using this happily for several months and adding a new share was is as simple as adding a line to a YAML file. I was never completely happy with it though, especially after I decided to deploy The Foreman in my lab.
Yesterday saw probably the biggest FLOSS news in recent times. Certainly the biggest news of 2014 so far :-) By some freak of overloaded RSS readers, I missed the announcement, but I did see this:
Day 1 at the new job. Important stuff first.. Where do I get my Red Hat ?— Karanbir Singh (@CentOS) January 8, 2014
I had a request on Reddit to share a document I wrote about connect Red Hat Enterprise Linux with Active Directory. The original document I wrote is confidential, but I said I would write it up.
This works for both Server 2008(R2) and 2012. If I recall correctly it will also work with 2003, but may need to minor terminology changes on the Windows side. From the Linux side, it should be fine with RHEL 6 and similar (CentOS and Scientific Linux). It should also apply to Fedora, but your mileage may vary.
That is a pretty drastic title, especially given that I spend a significant part of my day job working with EMC storage arrays. The other day I replied to a tweet by Scott Lowe :
@scott_lowe with things like Gluster and Ceph what does shared storage actually give apart from complications?— Chris Cowley (@chriscowleyunix) September 11, 2013
Okay, I know I am little slow on the uptake here, but I was on holiday at the time. The announcement of Virtual SAN at VMWorld the last week got me thinking a bit.
This is a post which breaks from the normal subjects of Linux and storage.
Today I am going to share a very simple recipe for what I drink when I am cycling. I have some fairly simple requirements for this.
FreeNX is a great remote desktop protocol. I find it more responsive than VNC and it uses less bandwidth. The biggest advantage though (in my eyes) is that it uses SSH to do the authentication. With VNC, each user has to arrange another password to connect to their VNC session.
As I promised on Twitter, this is how I automate a GlusterFS deployment. I’m making a few assumptions here:
Dell has announced the new PowerEdge VRTX (pronounced Vertex). The name comes from a vertex being “the intersection of multiple lines”, alluding to this being a mixture of a rack server, a blade server and a SAN.
Setting up the server is well documented elsewhere, the official howto works nicely for me. I use a Virtual TUN network (routed) with clients connecting via UDP 1194, with all the network config pushed out by the server. Follow the howto and you will get that at the end.
