It appears that you have snapshots, or atleast one snapshot, for this VM and you are running out of disk space on the VMFS volume.

Check the 'vdf' output and identify the volume where the VM is currently hosted.

You will have to make some freespace on the volume, either by deleting unnecessary files or by moving some of the VMs to a different volume and commit/discard the snapshot.

Hello,

You can also get this error if you have too many files on teh VMFS volume, somewhere around 31K or so files is the limit. Note if you are truly out of space then committing the snapshot will fail and you will need to make space. A quick way is to shutdown the VM and remove all vmware.log.# files from the VMFS for all VMs. Those are just there for debugging but can be safely removed.

The other may require you to move a VM off the VMFS, if this is the case you can not use the VMware tools very well for this except perhaps VMware Converter to copy a VM then you can delete the files manually.

Filling a VMFS past 80% is frowned upon, past 90% gives interesting errors.
