Hi,

I think you should check those 2 links about lockfiles :

VMware Knowledge Base (Manipulating a file on a Datastore fails with the error: device or resource busy / file is locked (1008728)

VMware Knowledge Base(Investigating virtual machine file locks on ESXi (10051))

Else, have you checked if the volume is in use ? If you can , temporarly remove any links between your VMs and the datastore then unmap -l the datastore then rebuild links.

If you use HA check if your datastore is not used for heartbeat (let me know if you need help)

I don't think you'll be able to monitor it only with esxcli command...

Someone succeed to automate it using PowerCLI , you can monitor the action using PowerCLI so :

Else, take a look at the step 7 in this link, VAAI Thin Provisioning Block Reclaim/UNMAP In Action - VMware vSphere Blog

It explain you how you can "monitor" the process via ESXTOP command (you can see the quantity of MB deleted)

But i didn't find any tools or cli to monitor the action as you can monitor the progress of anything in vCenter, sorry..
