Expanding VDEVs size without restarting

Hello guys,

I’m a newbie of Truenas and I need some help. I have a virtualization system including truenas running on hpe alletra. I need some functions like iscsi, smb and nfs that is why I started using truenas. My truenas pool runs on a single drive and when I need to expand the pool I change the disk size on vmware then login into ssh and use parted commands. It shows me that I expanded disk in Dataset page, but Data VDEVs section in Storage page still shows the previous capacity. I see the expanded capacity when I restart the truenas but I don’t want to that. Is there a way to see the changes without restarting?

Thanks in advance.
