Datastore files move issues

[GaelV]

Hi community

I'm dealing with vSphere 6.0 for a while but i've just experienced a new issue on a VMFS Datastore.

First issue :

I'm trying to Move an iso file to a different folder on the same datastore. First when i click on "Move to..." menu , it show a Copy action on vCenter's Recent Tasks and it takes too much times (more than 45min for a 4GB iso...

Second issue :

Once the file is copied/moved i don't know which word i have to use, the file is still present on the source and destination folder and i can't delete from the source folder.

I have the Unable to access file....error. Then when i succeed to delete it, it delete both iso (source and destination..)

Third issue :

I can't move/copy file without the Unable to access file...error

Is there something i missed ?

First issue:

Do your hosts use VAAI primitives to offload operation to the array? If yes have you tried disabling it? (You can do it in the UI I think)

On a side note I always had really bad performances when working with the datastore browser. I usually prefer to use tools like winscp.

Second/Third issues (probably relate to the same issue):

Can you check if there is a lock on the file? VMware Knowledge Base

Also, silly question: is it mounted on a VM?
