Expanding Virtual disk with just a few MBs

Is it possible to expand the Virtual disk(VMDK) on my VM with, let's say, only 5MB? Is there any "minimum value" when it comes to disk resizing? I can expand the virtual disk with 1Gb without any problems, tho.

You don't mention which is the virtualization environment.

I just tested in vCenter 6 and I was able to increase the disk size with 1MB.

Hello,

Could you tell us the guest OS involved as well as the VMware Product. In short it is possible, but it is not as simple as just expanding the disk.

The OS is Centos5/Centos6. One of the partition inside is EFS and only this partition needs to be resized after Virtual Disk is expanded. We have scripts which take care of the EFS partition resizing and all works fine if I expand the Virtual disk with ,let's say, 1G. Our Linux VM machines are deployed in variety of platforms : VMware workstation 12, ESXi5.5 , ESXi 6 , vCenter 5, vCenter6.
