Hello! How big is the disk right now? The command expects the new disk size, in kilobytes. So 1000000 is trying to change the disk to 1 gigabyte, not grow it by one gig. If that ends up shrinking it, you get an error.

Let me know if that's the case, please.

Hi swalberg,

Thanks for you reply !
We were trying to shrink the size, So that might be the cause for the error. However it works fine when we are trying to extend the size with the greater value compared to the current size.

Is there any chance to give the disk value in MB or GB instead?

Hi, I don't think you can shrink it through the API we're using. If I ever learn of a way to do that I'll put it on the backlog. I've got some concerns about the user experience so maybe putting it in a separate knife vsphere vm disk shrink command might be better.

Allowing it to accept human readable numbers like 100g or 200m is a great idea. Going to flag this as an enhancement.

Hi, Do we have a command to add the extra disk as well?

Hi Sean Walberg, Do we have a separate knife vSphere command to add extra disk to the VM post provisioning/Cloning ? Thanks & Regards. Bhargavi.A.
