Help ! Datastore space issue??

Esxi5.1 Essentials is host on dell t420 with raid 10 1tb space  setup just one vm with windows 2008r2 as backup dc dns print and file server

I am doing a migration and in the last stage of bring over the shares and the printers. I downloaded and tried to install the sp1 for 2008r2 and when I did my datastore went from 925gb free to 4.21 gb free?

I created a folder on the datastore just like when I created one for the install of 2008r2 ( I deleted from disk the 2008r2 folder) and then created and labled the new folder sp1   and then checked the box to power the iso up on reboot and when I did the sp1 update crashed and the error of no space for VM came up I went from 925gb to 4gb??? Error message when I try to delete the sp1 iso is

Error Caused by file (See attached picture)

Also this is thin provisioned

How do i fix this???:smileyconfused:

Hi,

Just to understand this:

It's a 1TB LUN you mentioned.

How much space was allocated to that VM? If you allocated 2TB through thin provisioning, you will of course will that disk.

Hi Spartacus,

I'm very relucant to open Word documents posted online for security reasons - if you just want to show a screenshot it would be much safer as an image file such as PNG or JPEG.

You've shown us how the datastore was configured - the issue is clearly one of where that space has gone.

Can you show us:

The snapshot manager?

The hard disk configuration for that VM?

You didn't show your snapshot manager - I'm interested in whether you've burnt space on snapshots. Can you show us what the snapshot manager shows?

However, it appears you have a 925GB LUN, with a 985GB VM on it. You were bound to fill this disk at some point. Assuming you don't have capacity to throw at this server, you'll need to shrink the VM. A reasonable method of doing so involves moving to a staging server, and resizing in the process.

Hi,

If the option to rebuild this server is easily enough done, I would take that route.

With a 925GB LUN, you could easily create an 800GB VM that provides for your needs and reserves > 10% of the LUN - I would do that.

I'm still interested in whether a snapshop is the issue here though, I've seen plenty of day one snapshots. Right click on the VM and open the snapshot manager - show us what you see.

Josh26 THis is 31/2 days old in build process and unless the snapshot manager is installed by default I didnt install it this is literally all Ive done is what I described above...So you feel its best to try to shrink it or would it be just as easy to redo this whole thing?

If I redo it what would you recommend on how to do it so I can have the vm with ad dns, file server and printserver on it and have my share that will take up 350gb actual space and may grow to 650 that a c drive with 80 a d drive with 650gb or 800gb i did above and a e drive with 80 gb for something else this is how the old server I am migrating from was setup..

What do you think and thanks again for you help

Spartacus, snapshot manager IS installed by default and it's not unusual to see a person creating a snapshot on day one (as I've said above) - so once again, please check your snapshot manager.

If you try to create your C: and E: to 80GB each, and 😧 to 800, you will use 960GB of capacity. Your screenshot shows you have 925GB of capacity, surely at this point - "would you recommend I overallocate again" is not really the question?

I went into windows and shrunk the 800gb partition from 200gb then exited out of this and powered off the vm and did a rescan of all datastores and my problem was gone along with my spaced partition.

Now it this issue fixed? can I recreate a partition and start adding shares and printers for printer server?
