@eddiejennings said in Appropriate Use of Hyper-V Checkpoints:

With this upcoming project of virtualizing our production stuff, I've been thinking through the appropriate use of checkpoints. I'm sure there are other articles on this, but this seemed to be a good read.

My grand idea is that checkpoints would be used before installing Windows updates or some upgrade to an application. You take the checkpoint, apply the update, and if everything breaks, you apply the checkpoint. If nothing breaks, then you delete the checkpoint.

I'm curious how this would be handled with a SQL Server VM or Redis VM. You'd update your VM, transactions start happening, then things break causing you to have to apply the checkpoint. Any transactions that were done would be lost, which upon further thinking probably doesn't matter, since you probably couldn't trust any data put into the database while the stuff was in the process of breaking.

You have to make sure you don’t have transactions coming in. Simple as that. Anything is a headache waiting to happen.

Makes sense. When I do maintenance on these normally, I stop IIS once downtime’s been announced, then do my work. So I’d just take the checkpoints at that point. I imagine once stuffs back up and I confirm things aren’t broken, Hyper-V just handles merging the avhdx file in such a way that SQL Server, etc is none the wiser. Or is there significant risk of stuff breaking if it’s running while that merge process takes place?

No real risk. Just performance loss.

And never enought to matter to any SMB workload I have ever had to deal with.

Thanks for all your input guys. This has really helped me.

I just finished upgrading my Fedora 26 laptop to 27 a bit ago.

So far everything working 100%.

I've been using it for my laptop and I like it a lot. Just on Cinnamon here, but everything has been very good since updating.

The only issue I have ran into so far is my mouse disappears in Virt-Manager when setting up a VM.

Ctrl + Alt fixes that.

I will have to give that a try.

Have you considered running it in a Docker container? That might help negate some of your problems.

They have a docker container for it? That'd solve a lot of problems, assuming it works (don't get me started on the non-working instructions for most docker containers.)

Woohoo, going to get this done today.

@scottalanmiller said in Dcpromo /forceremval wiped new DC. Help!:

My guess is that the second DC failed and never actually became a DC. If there wasn't solid confirmation of that, this would be the expected result.

How can you move the FSMO roles if that was the case? I would have expected that to fail as well.

Oh right, of course. It had to have worked.

@bigbear said in VoIP Taxes - Are you paying them?:

Still working for me...

Well, why does my phone refuse to connect a call with hangouts.... oh yeah.... Motorola, gr!

I can see RSTP is enabled on the stack. I presume this should mean I can connect stack member B to the firewall and the stack will put that in to a sort of disabled state, and will use should the link in switch A fail?

@zachary715 if you are getting extra slow speeds from it, I wouldn't know why.

Do you have the routes set up right for it on the sonicwall?

@scottalanmiller said in Backing up user data on remote computers:

We use NextCloud, then only back that up, not the remote user devices.

Are you running your instance of NextCloud in a VPS with extra block storage for your files, or using their enterprise plan?

We run out own.

Forgive me for seeming thick, but you mean on your own hardware in your office or at a data center?

We never run on premises for production.

I figured not; thus, they're at a colo.

No, we use cloud computing.

Somehow I'm confused, so you are running your NextCloud in a cloud server instance like Vultr?

Of course.

I'm assuming you're using the native sync clients? Are you using both Windows and Linux clients or just Linux? I've tried the Windows one on a couple laptops and found that the synching was really clunky and not working well. Have you run into any issues?

Both. All Linux internal, it's rock solid. Some Windows for external users, and they do have some issues. But... that's expected, it's Windows.

@bnrstnr said in Buying used server from another IT guy... Not sure what to look for:

I didn't even see the VM bit until I quoted it. I was just assuming since he was considering buying a used server in the first place that he may be interested in having something capable of doing more than just a NAS.

I did the opposite, assumed that since he was looking at a NAS that he only wanted storage 🙂

If these were my servers, I would want to see bandwidth usage too, especially if the cloud provider is charging me for it. The PRTG approach looks like a really good option.

I've heard good things about Sensu as well.

But no matter what you use, you need to be able to know what normal operation (performance, capacity, utilization) is like across the servers so you will truly know if the behavior you see is an outlier or expected behavior (i.e. a SQL VM spikes in CPU and memory usage because there are a ton of queries running for order inserts at the end of the day, etc.).

@momurda said in WSUS preparation for Windows 10 Feature Upgrades:

Wow. Definitely not doing that if I have the same problems as you.
Ill just go around and install the upgrade manually.
Not even sure why MS still has WSUS, it is nothing but problems unless you spend hours a week fixing and maintaining it.

I hear ya, this took me an hour to research, make sure to gather correct logs and then do the how-tos.

@stacksofplates
Hi, I need to configure every day the server need to be powered on automatically some time and the same need to be powered off in the evening. Power off i was done through scheduled task in windows. But powering on is the challenge. I tried with lambda option but having some error

Are you trying to save some money on the amount of hours the server is powered on a month?

Here I thought that was the whole point of using things like EC2.

Best that you found out now. It's a common misconception that it is about "powered on" versus "existing." The point of cloud computing is creating / destroying to save money, not powering on and off. The later we could do before cloud.

Yes, I'm very aware of this, which is why I brought up the automated create/destroy so much earlier in this thread!

Looks like a neat idea. Treat the OS as a database, standard query language across platforms.

@tim_g said in Virtual Firewall:

@scottalanmiller said in Virtual Firewall:

Why two firewalls?

DMZ --> Perimeter Network --> LAN?

That's how it used to be. The DMZ meant the area between the firewalls.

Pretty limited options for hardware monitoring of hardware RAID. Almost always done via software, somewhere.

@dafyre said in Suggestions for new APs and Firewall:

This is for a school, not an SMB. With out some form of traffic shaping somewhere, their bandwidth would be overrun with torrents.

@Markferron can correct me if I'm wrong, but right now, I think the Meraki APs are where the bandwidth shaping is being done now.

Yup I have rules on the APs and the MX400. They should all be the same as far as bandwidth limits, just in case.

@tim_g said in Looking for a very basic solution for building/maintaining company intranet:

We should have a salt states file tag, strictly for salt states files. I'll populate it as I make them. I see you have a few on here that could be added.

I like that idea.
