Posted on 2013-11-03
Last Modified: 2013-11-03
I am trying to increase the capacity of ESX Datastore from 32.50GB to 113 GB as shown in the screenshot.

When I click the increase button, it opens up a window but nothing shows up in the window.

ANy help will be very much appreciated.

There is no screenshot.

However it does not matter.

The partition or disk you have increased in size, is it part of the default ESXi OS installation?

e.g. does ESXi OS installation and current datastore share the same disk?

if so, you will need to modify the partition, at the Console, and not using the Wizard to perform the installation, where normally you would use the Increase button, and select the new space or disk presented to increase the datastore.

Is this real ESXi on a server or in VMware Workstation or Fusion?

No snapshot attached.  Are you trying to do this in vCenter or on the ESXi host directly?  There are some issues in doing this in vCenter, you can go directly to the ESXi host and try it from there.

I remembered discussing the commands to use previosuly in this question you asked in August 2013, here it is if you have forgotten:-

Yes, I thought as much, screenshot does not change anything, other than this is VMware Fusion.

Your options:-

1. Rebuild your ESXi server, creating a vitual disk of 1GB for the ESXi installation, and then create another disk, with the correct datastore size.

2. See original article, that you understood, on how to increase the vmfs partition size, using


3. Add a new disk to ESXi VM, and either use this disk, as datastore2, or ADD this disk to datastore1.

Once you have added a new disk to the VM, after a shutdown of ESXi, you should be able to add this disk, to existing disk, to increase the datastore size....

e.g. you will then see a disk in the box,which is not showing anything at present.

Do you understand your options?

and in the previous article, I explained how to use it, and you replied:-

" I have reinstalled the ESXi with more disk space,, "

So from the last answered question you have the information to use partedUtil.

Personally, I would try options 1 and 3 as this is just a Lab. It's not production.
