NTFS Permissions On A File Server From Hell Saved By SetACL.exe & SetACL Studio


Most IT people don’t have a warm and fuzzy feeling when NTFS permissions & “ACLing” are being discussed. While you can do great & very functional things with it, in reality when dealing with file servers over time “stuff” happens. Some of it technical, most of it is what I’ll call “real life”. When it comes to file servers, real life, especially in a business environment, has very little respect, let alone consideration for NFTS/ACL best practices. So we all end up dealing with the fall out of this phenomena. If you haven’t I could state you’re not a real sys admin but in reality I’m just envious of your avoidance skills Smile.

You don’t want to fight NTFS/ACLs, but if it can’t be avoided you need the best possible knowledge about how it works and the best possible tools to get the job done (in that order).

If you have not heard of SetACL or DelProf2, you might also not have heard of uberAgent for Splunk, let alone of their creator, community rock star Helge Klein. If you new to the business I’ll forgive you but if you been around for a while you have to get to know these tools. His admin tools, both the free or the paying ones, are rock solid and come in extremely handy in day to day work. When the shit hits the fans they are priceless.

Helge is an extremely knowledgeable, experienced, talented and creative IT Professional and developer. I’ve met him a couple of times (E2EVC, where he’s an appreciated speaker) and all I can say is that on top of all that, he’s a great guy, with heart for the community.

Having the free SetACL.exe available for scripting of NTFS permissions is a luxury I cannot do without anymore. On top of that for a very low price you can buy SetACL Studio. This must be the most efficient GUI tool for managing NFTS permissions / ACLs I have ever come across.

Not long ago I was faced with a MBR to GPT LUN migration on a very large file server. It’s the proverbial file server from hell. We’ve all been there too many times and even after 15 years plus we still cannot get people to listen and follow some best practices and above all the KISS principle. So you end up having to deal with the fall out of every political, organizational, process and technical mistake you can imagine when it comes to ACLs & NTFS permissions. So what did I reach for? SetACL.exe and SetACL Studio, these are my go to tools for this.

Check out the web page to read up on what this tool can do for you. It very easy to use, intuitive and fast. It can do ACL on file systems, registry, services, printers and even WMI. It helps you deal with granting ownership and rights without messing up the existing NTFS permissions in an easy way. It works on both local and remote systems. Last but not least it has an undo function, how cool is that?!  Yup and admin tool that let you change your mind. Quite unique.

As an MVP I can get a license for free form Helge Klein but I recommend any IT Pro or consultant to buy this tool as it makes a wonderful addition to anyone’s toolkit, saving countless of hours, perhaps even days. It pays itself back within the 15 minutes you use it.

Other useful tools in your toolkit are http://www.editpadlite.com/ as it can handle the large (550-800 MB) log files RoboCopy can produce and some PowerShell scripting skills to parse these files.

The Hyper-V Amigos Showcast Episode 4: TechEd North America 2014


In episode 4 the original Hyper-V amigos (also 4) get together for a chat. Yes, learn about the history of the name and about the what happened at TechEd North America 2014. How Aidan won speaker idol. How I got to be on stage.

Hans is a bit tired but extremely happy due to a certain soccer game outcome Smile. The orange shirt is not by accident. We discuss the keynote, the content, Azure announcements … we jump into one of our favorite topics storage and storage spaces and speculate a bit about vNext timing.

Enjoy!

TechEd North America 2014 Session


There is something extremely rewarding about seeing your name on the intro slide of a TechEd USA presentation. I helped deliver What’s New in Windows Server 2012 R2 Hyper-V together with Ben Armstrong yesterday and it was quite the experience.

A big thank you to Ben and Microsoft for the confidence they have shown in me and the opportunity to do this. A mention to our CEO who has the ability to look beyond the daily needs and facilitates his and encourages his employees to get out of the village to learn, grow and prosper. This is the principle one of my high school teachers lived and worked by, help people be all they can be.

The IT community around the Microsoft ecosystem is both a local and a global one. In this day and age knowledge gets shared and flows freely. People work with people and with organizations. No one gets anywhere in isolation.I’m happy to see so may of my buddies do so well. It’s great to see people succeed, grow, enjoy their work and reap the fruits of their efforts. Look at Benedict Berger who was presenting in the room next to ours or Aidan Finn, a long time community member and experienced speaker who won speaker idol and by doing so secured a speaker slot for next year. This has many reasons and one of them is people believing in you and giving you the chance to grab opportunities. To those I say, thank you very much!

Attending And Presenting at TechEd North America 2014


As you might well know I’m attending TechEd North America right now. I blogged about that. But I have to correct this a bit. Today I will also be presenting together with Ben Armstrong and help him deliver session DCIM-B380 What’s New in Windows Server 2012 R2 Hyper-V.

Ben Armstrong, Principal Program Manager on the Hyper-V team, will be showing you the wealth of features that provide capability, scalability, performance, availability and reliability in Windows 2012 R2 Hyper-V that make it THE capable and scalable cloud OS.

I’m honored to be able to show case a few of the technologies in Windows 2012 R2 we are leveraging in production today. So can you, really!

The Hyper V Amigos Showcast Episode 3: Live Migration


Here’s the 3rd episode of the Hyper-V Amigos show cast. As Carsten was overwhelmed with work (running your own business is very hard work) and had some issues with his storage spaces lab due to testing we’re discussing live migration optimizations in this installment.

 Carsten Rachfahl and I had a lot of fun again, even during the second take, yes we needed one. Apparently these software thingies require me to click on “record” Smile as there is no intelligent agent yet to act on my intention.

Carsten & I discussing & showing some live migration optimizations

 

I have written many blog posts on this subject already and I’m sure I’ll write more. Optimizing the use of the hypervisor (Hyper-V) across the entire storage, compute/memory & networking stack is one of my specialties and I enjoy this part of my job very much. I also like to share this information as real.

I’m sure you’ll agree that Hyper-V has come a long way in short period of time and I’m pretty sure we’re going to see Microsoft continue this pace for quite a while.

I have a blog post coming out (it’s in the queue) on my 4 top recommendations for optimal live migrations but here’s a search of relevant blog posts on this topic, and we referred to some of them during our show cast:

When you’re done reading al these posts on live migration you’ll have earned a nice refreshing beverage of your choice Mug.

One more thing, if you like these show casts let us know! Last but not least, I’m doing a demo heavy (only) session at ITProceed on June 12th 2014. Many local experts, community members  and I will be around afterwards to discuss these technologies.

DELL Enterprise Forum EMEA 2014 in Frankfurt


As you might have noticed on Twitter I was in Frankfurt last week to attend DELL Enterprise Forum EMEA 2014. It was a great conference and very worthwhile going to. It was a week of multi way communication between vendor, marketing, engineering, partners and customers. I learned a lot. And I gave a lot of feedback. As a Dell TechCenter Rockstar and a Microsoft MVP in Hyper-V I can build bridges to make sure both worlds understand each other better and we, the customers get their needs served better.

Dell Enterprise Forum EMEA 2014 - Frankfurt

I’m happy I managed to go and I have some people to thank for me being able to grab this opportunity:

  • I cleared the time with my employer. This is great, this is a win win situation and I invested weekend time & extra hours for both my employer and myself.
  • I got an invite for the customer storage council where we learned a lot and got ample of opportunity to give honest and constructive feedback directly to the people that need to hear it! Awesome.
  • The DELL TechCenter Rockstar program invited me very generously to come over at zero cost for the Enterprise Forum. Which is great and helped my employer  and myself out. So, thank you so much for helping me attend. Does this color my judgment? 100%  pure objectivity does not exist but the ones who know me also know I communicate openly and directly. Look, I’ve never written positive reviews for money or kickbacks. I do not have sponsoring on my blog, even if that could help pay for conferences, travel expenses or lab equipment. Some say I should but for now I don’t. I speak my mind and I have been a long term DELL customer for some very good reasons. They deliver the best value for money with great support in a better way and model than others out there. I was sharing this info way before I became a Rockstar and they know that I tell the good, the bad and the ugly. They can handle it and know how to leverage feedback better than many out there.
  • Stijn Depril ( @sdepril, http://www.stijnsthoughts.be/), Technical Datacenter Sales at RealDolmen gave me a ride to Frankfurt and back home. Very nice of him and a big thank you for doing so.  He didn’t have to and I’m not a customer of them. Thank buddy, I appreciate it and it was interesting ton learn the partners view on things during the drive there and back. Techies will always be checking out gear …

Dell Enterprise Forum EMEA 2014 - Frankfurt

What did all this result in? Loads of discussion, learning and sharing about storage, networking, compute, cloud, futures and community in IT. It was an 18 hour per day technology fest in a very nice and well arranged fashion.

I was able to meet up with community members, twitter buddies, DELL Employees and peers from all over EMEA and share experiences, learn together, talk shop, provide feedback and left with a better understanding of the complexities and realities they deal with on their side.

Dell Enterprise Forum EMEA 2014 - Frankfurt

It has been time very well spent. I applaud DELL to make their engineers and product managers available for this event. I thank them for allowing us this amount of access to their brains from breakfast till the moment we say goodnight after a night cap. Well done, thank you for listening and I hope to continue the discussion. It’s great to be a DELL TechCenter Rockstar and work in this industry during this interesting times. To all the people I met again or for the first time, it was a great week of many interesting conversations!

The Hyper V Amigos Showcast Episode 2: Unmap


We’re back for our second episode of the Hyper-V Amigos show cast. In this episode we discuss and demonstrate UNMAP in Windows Server 2012 R2 a bit. As always it was fun to work with Carsten Rachfahl.

2 Hyper-V Amigos having fun discussing UNMAP

 

Here’s our fun and unscripted (other than the PowerShell used in the demos) attempt at showing you UNMAP behavior with Hyper-V and a DELL Compellent SAN

If you want to read more on our experiences with UNMAP search my blog https://workinghardinit.wordpress.com/tag/unmap/. I have prepared some links for you.

I still need to get the slides uploaded, but all that info is in the blog posts.

Enjoy!

EDIT:

In relation to the question below about not much difference between Dynamically expanding VHD/VHDX. That demo didn’t work out so well here so I include  some screenshots of a comparison I just ran:

This is the dynamically expanding VHDX. on an IDE controller, no ODX.

image 

This is the dynamically expanding VHD on an vSCSI controller, with ODX.

So yes, losing ODX makes things slower for dynamically expanding VHDX, but it still beats a Dynamically expanding VHD that has ODX.  A VHDX is a lot better at dynamically growing than a VHD.
