Could not power on device: no space left on device ?

Hi all,

Has anyone encountered this message (att) when creating a VM ?

I 've created an .img file on the W2K3/Starwind server of 10Gb.
Added it to the storage via VI client. Ok
Created a VM with 10GB HD. Got just over 1Gb of free space back !!!!!
Tried several other lower HD sizes.
At the end 6GB HD gave me a 5.39GB HD free space.

Even with an .img file of 12Gb no more then 5.39Gb of free space is available !!!

Is this a know 'feature' of the free version ????

Thanx Jaap

- ESXi3.5U4 server
- W2K3SP2/Starwind server

The free version allows you to create the image files up to 2 TB. Why don't you create say a 100 GB image file and store your VM there?

Thanks.

Hi Robert,

I made several image files on a per server base.
I like to have things in compartments to be able to throw things away without destroying everything.
Just in case an image file would (can?) get corrupted.

What I exeprience is odd.

- I create an SW image on te phyciscal SW server.
- Add the storage on the ESX box.
- Add a new VM 'on' the ESX
- e.g. 10Gb image file gets a proposed 8Gb on the ESX boc
- when I complete the configuration I get a mere 1.3Gb available space !!!
- with the same 10Gb image file and I lower the disk size on the ESX box to 6Gb i get 5,3GB ???

We get the same in our testing lab actually, but that is related to a VMFS (as well as other clustered file systems that you format the images with). It for some reason creates a large overhead, not sure why. In this case the only recommendation would be to create larger image files.

Thanks.
