Reclaim space does not work in vsc



we try to reclaim space using the vsc.

It is not working and it always terminates with the error unknown,

as you see in the attached screenshot.

It would be nice to know if anybody succeeds using this feature and if you have any suggestion how to debug it.





Re: Reclaim space does not work in vsc

VSC could be used to reclaim space ONLY from NFS-based VMs with prerequisites

below 2 kbs might be helpful

Unable to use the ESX reclaim/unmap function on a thin provisioned LUN -

What VAAI configurations are supported on Data ONTAP storage controllers? -

Cannot find the answer you need?  No need to open a support case - just CHAT and we’ll handle it for you.

Hi yaoguang,


yes we are using a nfs datastore and no lun

so it has to work but it doesn't.


Thanks a lot for your reply,
