To find out what is/was causing this, you need to investigate from within the guest OS. Maybe someone stored a huge amount of data to the FS, or copied something!?
In case it's a Windows fileserver, you may use e.g. TreeSize to find out what's consuming the space.

Nobody add big size files to GuestOS, and as you can see at attachment that i attach now of screenshot of the size of guestOS partitions, there size is half of what VMDK allocated.
Hi,
did you run a Defrag on the disks??
Hi,
How it will help?
Defrag in window 2012 and later should organize the freespace and tell VMware to reclaim it. This is for 6.0 but I believe it still applies. You probably used it all and then it was deleted in the guest os, but VMware hasn't reclaimed it yet.
Thank you Sjesse!!
Now i'm made optimization to my server 2016, and i'ts worked great the allocated space of VM got small again to his natural size.
and what about server 2008 R2, it will also work?
Best Regards,
Run "df -h" in the ESXi datastore in the corresponding directory: /vmfs/volumes/{datastore}/ ...
Check all subdirectories size, maybe you find something else related to the storage capacity size.
After that check the vmware.log file and also event viewer in the VM guest OS.
what this command doing?
it as to be run from that path /vmfs/volumes/{datastore}/ ?
it could be run online with out take offline virtual machine?
Run this in the following path to check contents of exact directory: disk usage and max depth show only this directory's files (one level)
du -chx --max-depth=1
No need to power-off the VM, even it's better to be power-on because you need to find the cause of the problem in power-on state.
Its not available I'm afraid.
Try to storage vmotion (keep the same format) and check again!
I have vmware essential license, this license doesn't support vmotion.
