why I can not increase the Data Store size?

After I extended the LUN size by 100 GB. I am trying to increase the datastore size and each time i try, i get the following error

Call "HostDatastoreSystem.ExpandVmfsDatastore" for object "datastoreSystem-1421" on vCenter Server "vCENTER.NET" failed.

Can you try connecting directly to an ESXi host using vSphere Client and attempt the operation from there?

Also, if the datastore had completely filled up this may be relevant: http://kb.vmware.com/kb/1039239

Check the vmkernel log for similar errors.

thank you for your response p_hallp_hall

Yes I have tried to connect directly to an ESXi host using vSphere Client and it did not work.

I even restarted the SAN and the host.

I would avoid deleting anything unless you're sure that's the reason.

There's a vswap file in there so presumably the VM is powered on - powering it off should get you some additional space, if that is indeed the problem.

What do you see in the vmkernel.log at /var/log after the failed operation? Can you take a copy of that file and attach here?

One other point for now - you mention that you tried the operation directly on a host. It seems from a note here that the host you choose is significant:

Did you attempt the operation from the host where the powered-on VM is registered?
