seems like the snapshot files are there. one way is to commit the snapshot or clone the VM to another VM which would commit all snapshot.

No, we have got only 2 weeks old snapshots (we have a lot of data in this 2 weeks)

So I can't clone it and I cant commit snapshot.

commit and clone does not delete any of the 2 weeks data but to consolidate them into a single VMDK.

clone is only available when you have vcenter server. when committed to a single VMDK you might have a chance to power up the VM again. good luck.

You can recreate your descriptor file (thats all a .vmx is) the .vmdk is the important file.

You can also clone the vmdk through the cli with vmkfstools. You would need to make sure that your VMDK CID and ParentCID's are in order and looking for the appropriate VMDK that the snapshots belong to. Once that is verified you can run vmkfstools -i /vmfs/volumes/If you found this at all helpful please award points by using the correct or helpful buttons! Thanks!
