VMWare

I have a virtual server that is thick provisioned to have 300GB. This server is in a data-store alone. The data-store has 400GB.

This environment has been this way for several years.

Lately the additional space in the data-store has been getting used.

How is this possible?

Out of curiosity, have you checked your snapshots in your snapshot management. That's what I would at first.

Firstly, the datastore not only stores the virtual machine disk of 300GB, but also other temporary files, and more importantly the SWAP file, which is equal to memory allocated in the virtual machine, so if you have allocated 32GB to the VM, then 32GB will also be eaten up on the datastore.

Also do not store ISO on your datastore.

As my fellow Expert has stated, you may also want to check for dangerous SNAPSHOTS!

The above only happen when you have snapshots - because once you create the snapshot it will not use the actual disk and start utilizing the free space on the datastore.

you may try below  steps to fix the issue.

1# Consolidate VM.
2# Create snapshot and perform "DeleteAll" operation.

The problem was indeed snapshots.

My Veeam Backup created a snapshot and did not remove it, because the backup was manually stopped prematurely.

Thanks for the help!!!
