I am using ESX3.X. I tried to extend a disk using VMKFSTOOLS but I can't as I am getting the  error Message as:

Failed to extend disk: One of the parameters supplied is invalid (1)

I used the following command:
vmkfstools -X 20G <v.VMDK>

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

otherwise try VMware Converter, to increase the disk and partition in once process or procedure.

are you trying to reduce the size of the disk?

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:
vmkfstools -M <diskname>

Please let me know does the converting the disk will cause any Data Loss?

Thanks

No conversion does not lose and data.

if it's imported from 2.5, you will need to use -M
