I have few VMs on a datastore and the datastore is nearing the capacity.
What is the best way to free up the space? Will it help if I move the VMs away from the data store?

You can increase datastore capacity if this is LUN assigned from SAN..

Or you can add another storage as new data store and then move VMs across..

thanks

I have deleted some space on the VM and this did not help.
How can I reclaim these space.

Deleting files inside a virtual machine, does not effect the size of the virtual machine disk, on the datastore.

The size of the virtual machine disk (vmdk) on the datastore is fixed, whether you delete files inside the VM or not.

The only way to shrink the VMDK (virtual machine disk) is to complete a V2V using VMware vCenter Converter Standalone, after you have removed files inside the OS. At conversion time, during the wizard, you will have the option to specify a new virtual machine disk size, e.g. make it smaller, once conversion has been completed, delete the original VM.

Even though you may be see any snapshots list in the GUI for your VM's you still may have an orphan snapshot connected to a VM. I would suggest browseing your datastore folder and check for VM with VMDK like:  vmname_0001.vmdk.

Check for any crash dump logs as well.

Remove any unsed ISO / install files.

You could try to do an inplace storage migration to change your VM's from thick to thin provisioned.

I was told that storage venders have their own tools to reclaim the space, like netapp has vsc, dell has hit etc. I am going to talk to them.
in th eman time I am going to do storage motion.
