Esxi vmdk out of disk space

One of our highly utilized vm is giving the error that there is no more space for the the vmdk shown in the following image.

enter image description here

The VM won't start because of this issue, so I'm not able to delete data from the volume at OS level.

The virtual machine has 3 snapshots but the consolidate option is greyed out. Screenshot from the vm's datastore belowenter image description here

You need to either

  • Extend DataStore size (can be done online) or
  • Storage vMotion some of the other VMs off this Data Store.

The ultimate goal is to free up space on the DataStore so you can unfreeze VM. And by the way - freeing space from the OS level won't help you.
If your vmdk is thin - it will grow in size over time, but will not shrink when you clean underlying OS.
There are some tricks to reduce vmdk size again available, but those require bringing VM down (not online process).
