are you trying to reduce the size of the disk?<br />
<br />
You must specify the size you want like to Extend To and not how much you want like to Extend By.

There is no snap shots. The other thing is I can use VMware convertor but the size of the VM is too big so it will be time consuming. I think the VMDK file is imported from ESX2.X. So I think it should be first converted with:<br />
vmkfstools -M &lt;diskname&gt;<br />
<br />
Please let me know does the converting the disk will cause any Data Loss?<br />
<br />
Thanks

No conversion does not lose and data.<br />
<br />
if it's imported from 2.5, you will need to use -M

I am using ESX3.X. I tried to extend a disk using VMKFSTOOLS but I can't as I am getting the &nbsp;error Message as:<br />
<br />
Failed to extend disk: One of the parameters supplied is invalid (1)<br />
<br />
I used the following command:<br />
vmkfstools -X 20G &lt;v.VMDK&gt;<br />

I really wonder as I have done this many times without error. I really want to know what is the real cause for this issue and how can I resolve this. Thanks<br />

VMware issue while extending a disk through VMKFStools

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
