And doesn’t it feel good

 

It’s taken a while but I’m clean now. I look back on my dependency and hate all those wasted years. What I could have achieved if I had never been hooked or if I had cleaned up my act sooner? Like most people with a problem I didn’t accept it was a problem though. Getting clean took a significant event in order for me to take a good hard look at what I was doing! It happened like this…

I got back from a week away with my family and fired up the trusty old desktop. It is a hex core AMD machine that I assembled myself (of course) a few years ago. It was running Windows 7 Ultimate (not sure what was so ultimate about it) and up it came eventually and I logged into the domain (yes, of course I run an AD domain at home, don’t you). After a few moments I got the dreaded blue screen of death, not something I’d seen for a while, but I sure knew what is was. I hard reset the machine and got the usual disk repair message…

Except at the end it told me that it couldn’t repair the disk. Well, to be honest that was no surprise as it never has before so why I thought that it would be different this time I don’t know. Another hard reset and I had something new; an unrecoverable I/O error. That’s it, no other information, just that. No clue as to which I/O device it might have been struggling with, nothing. After an hour of struggling to get the system up I decided that I was through with Microsoft and all its Windows minions. I was going to free myself once and for all from this tyranny.

I tested the hardware and found it was fine. And while yes, of course I could have reinstalled Windows, I was then facing the inevitable challenges of it already being registered and having to beg Microsoft to please let me reregister it. Then of course the many hours of downloading updates, fighting against the bandwidth needs of my son’s PS4. I live in a very rural area so high speed broadband doesn’t mean what you think it does… Then of course the same set of struggles putting on Microsoft applications that are massively bloated, have similar licence challenges and will also want to download their own set of updates. I’d be lucky if I was up and running a week later.

All of this flashed across my mind and in a brief instant I considered the option and discarded it. No, that way was not for me. I had walked that road too many times before and where had it got me? Enslaved to Microsoft, trapped with an operating system which changed it’s look and feel drastically in every iteration, taking away much loved features and replacing them with things that my hardware struggled to live with (no, I don’t have a touch screen as why would I want fingerprints all over my monitor). Instead I did what I should have done years ago, I downloaded the best desktop version of my Favourite UNIX – PC-BSD. The new version only runs on 64bit (unlike FreeBSD which it is based upon), but that isn’t a problem with my hex core AMD.

An three hours of downloading later (I did say I had pretty poor broadband – thanks Demon) and 15 minutes of installing later and here I am. A free man; cleared of my dependence on Microsoft and looking forward to life. An of course the core system is the same as the other OS which I use, Mac OS X. Both are based heavily on FreeBSD (as is my son’s PS4).

And with such a huge range of applications to choose from, all of which are free, I’m entering a strange new world where my computer can do exactly what I want it to, in the way I want it to and somewhat faster and cooler than it did before.

Wish me luck in my new Microsoft free adventure.

Disaster Recovery Planning

by Admin 22. September 2013 14:19

 

or how not to be in trouble with your users

 

Last week I had a service outage due to an incident that I had not properly planned for. Before I tell you about it, I should probably remind you that I run what my wife describes as an overly complicated home network. She is non-technical, so everything is the network and when something doesn’t work the network is down. Fortunately we can agree on one thing; when the network is down it is my fault!

 

The nature of the outage

 

Having arrived home after some foreign trip (I may just have been in the Grim North, all trips just blend into one now) I was confronted by a group of dissatisfied users. I say a group, I really mean my wife and daughter. My son is technical so if he had been inconvenienced he probably would have just solved the problem. Upon further inquiry I discover that no one can log into the domain.

Before we go any further I should explain that I run an AD domain at home primarily for my own amusement. I could provide many of the home IT services without this but felt I needed to know more about AD management and so the rest of the family need to be my willing assistants. Running an AD domain really wasn’t a challenge so I decided to make it hard for myself by doing it without the aid of Microsoft. I run a Samba 4 domain, which is possibly one small step beyond experimental software. Don’t tell my wife!

Now I am a little ADHD about resilience so I have standby hot and cold servers ready to spring into action. I have redundant disks in redundant servers that have redundant network cards. Alas I only have the one data centre and spinning up a cloud based solution is a little beyond my means. Besides, if the whole house has gone I suspect my wife won’t let me fiddle with IT! So with all this redundancy, what on earth could have taken my domain out?

Well it would seem that a combination of factors were to blame; aren’t they always? The first problem was that I was running on a single domain controller. My secondary domain controller was down awaiting an upgrade. I could have had it running but I was waiting for a new version of my favourite OS FreeBSD and had decided not to upgrade until I could put the new OS on. I could have had the old version running of course but that was a (poor) decision I had made. So there, right away, was part of my redundancy gone; simply because I had made some operational decisions which had affected my DR solution. I knew what I was doing but did it anyway.

But even so, what about the rest of it; surely I was safe, what went wrong? Well unfortunately I was preparing for the wrong disaster! The disaster I had prepared for was the complete loss of a server. Systems would have detected that on the network and leapt to take action. The disaster I got was the failure of the Domain controller software and nothing else. The software kept running but not in a meaningful way. Nothing detected that there was a problem so my domain controller hummed away providing all other services (DLNA media server, Subversion server etc.) but not domain services or file sharing. As a result the mission critical service of providing access to homework and other files failed silently leaving my most important users unable to access their core applications and data!

And what caused this disaster I hear you ask? Was it some software flaw or perhaps a security violation? Not quite. It would seem that a ladder, left against a wall in my data centre (for that read separate office building near the house) fell over and hit the keyboard on the KVM switch attached to my core server stack. It happened to be switched to my domain controller and worse than that logged in (I know, shock, horror). Whatever set of keyboard codes it produced sent my DC into a tailspin without actually killing it (or interrupting the network stack so it looked dead).

All those preparations I had taken were worthless as I was preparing for the wrong disaster and the wrong set of symptoms. Things were made worse by my own poor operational decisions regarding DR and standby equipment. And what lessons have I learned? Well my ladder is now tied down…

If the abortion is take up, the bleeding and the cramps let up. As things go oneself encase endure irretrievable in a way during the precurrent stages as to favorableness, better self rust edge in so your calling only yesterday themselves are 63 days excepting the point your curtains feminine caesura began.

Overly complicated home IT

by Admin 9. July 2013 17:54

So over the coming months and years I’m planning to blog about my home IT and I should probably start by saying something about it. My wife has quite a bit to say about it but most of what she says isn’t printable. The one point she does make consistently is that it is needlessly complicated. To my mind that is a very relative term. From the point of view of providing the service and meeting the family needs, she may have a point. Certainly the children’s homework is backed-up and anyone can sit at any PC and access their files, email and other services. It may be said that being able to access our video library from any TV in the house isn’t entirely necessary or stream music and video to iPad’s, and other devices is a nice to have but her view is that none of this is particularly necessary.


I feel that the point has been comprehensively missed here and in this I feel that I have the support of my children. If something is possible then surely we should be doing it at home. Every facility marks us out as more advanced than the apes and is, therefore essential. Of course I haven’t stopped at streaming media to smart TV’s. Oh no; I have a subversion server which allows me to do revision control of the software I write and I have a MySQL database for all my local database needs (whatever they may be).  I accept that running the samba4 domain controller may be a little over the top, but the Virtual-Box server running an array of virtual Windows servers on FreeBSD are clearly essential.


So, a little taster…


The Hardware


My primary server runs samba 3 and is a quad core single processor AMD machine with 8GB of memory. This provides file and print services for the family and also streams media to devices. It has a Gigabit Ethernet PCI card as the on-board ports are only 100Mbit. It has a 1GB and a 2GB internal disks and two 1.5GB external disks all SATA3. The two external disks are connected to a 3ware controller. There is nothing very cleaver about this machine. It is VERY stable and has been up for 181 days (as of July 9th 2013). And the only reason it was rebooted was I upgraded to FreeBSD9.1 from 9.0.


My secondary server is a DL360G5 (thanks Rita). It is a dual process Xeon 5450 machine which means 8 cores at 3GHz. It runs 16GB of ram and is packed full of 2.5 inch disk;  five SATA3 disks and one SAS high speed disk for the swap device. I also run ZFS though I boot onto UFS. This machine runs Samba 4 as a domain controller and is what I plan to switch too in the near future. I have some performance issues with Samba4 which I’m trying to overcome. Likethe previous machine it runs file and print services; it is also my primary Subversion server and also runs the media streaming.


My Development system is a home built SuperMicro system in a big tower case. It also has a 3ware controller and has 8 750GB 3.5 disks with one boot drive and seven un-mirrored drives in a single ZFS pool. Even though I have no BBU I have turned on the write cache on this machine to squeeze ever single bit of performance out of it. The processors are two 2.8GHz Xeon 5440’s and I have 20GB of memory. It is a secondary samba4 domain controller and runs VirtualBox-ose and hosts currently three instances of MS Server 2012.


There are various other machines, ranging from my now decommissioned DL380G3’s to a Raspberry Pi but those above represent the core compute power! I’ll share some of the secrets of those systems in further instalments. I may start with how I made a Fan bracket out of sheet steel to mount two old case fans directly above the CPU heat sinks in the SuperMicro tower to solve the heat problem...
