BRRABill's Field Report With XenServer
-
XS (and XO) show the provisioned size of the virtual disk. Is there a way to show how much space it is actually taking up?
(For example in Hyper-V you could just look at the size of the VHD.)

Same, you either look at the storage device and query it and/or you look at the size of the filesystem image file.
-
Yep there is.
Go to the Dashboard firstFrom the dashboard find the Storage Repository (SR)
Click on it.
Now scroll down a little and you'll see your VHDs
-
I fumbled around for about 5 mins before I bumped my way into this.

Is that functionality available in XC or XO?
In Hyper-V you can right click the storage and it tells you provisioned size and size on disk.
-
But that doesn't tell you virtual drive by virtual drive. Only the main XS drive. (Which you can also see in XC.)

I guess in reality it doesn't matter. You'd be managing the drive sizes in each VM, so it would never be an issue.
I just like to know hey ... this virtual disk is only 10% full without going into the VM itself to check. Pretty easy to do in Hyper-V. I figured it was in XC/XO as well, but I was just missing it.

Aww.. OK I gotcha now..
i thought there was a place to see the assigned space vs the used space - can't see to find it right now.. of course I'm guessing the VDH doesn't shrink when you delete things.. so it will only show the max size it ever was.I thought you only wanted to see how large an assigned VHD was - not the actual internal usage inside the VHD... but I understand now.
-
Also - @BRRABill the ability of Hyper-V Manager to show you the used storage space might only apply to Windows based VMs. That seems pretty likely.

I guess my thinking was that if you overprovisioned a bit, and one of your servers was going nuts, it would be nice to easily see which one it was.
But there should be checks on the individual servers to prevent that from happening.
I am assuming it can be done directly in the XS file system. Was just wondering if it was in XS/XO somewhere.
-
and now I'm back to not following.
-
-
here is one of my 2012R2 servers on ESXi - from here I can't tell how full the VHDs are, only the assigned size.
I might see something different if I thin provisioned those machines, but back then I never did that, so i can't show you what that looks like.
I'm guessing the insite you have to Windows VHDs is the nature that it's Windows on Windows, but if it was a Linux VM, I'm guessing you wouldn't get that information.

Setting up a test of that as we speak.

You mean you want to know how utilized the filesystem is inside of the VM?

If you overprovision, that wouldn't be what told you. That's not the right information for that problem.

No, you need to either not overprovision or you need to monitor to make sure that you don't run out of space. The individual machines have no idea.

Yes.
BTW: I installed Ubuntu on my Hyper-V box, and it still shows the usage.

Right, that I understand.
