Today it is an offline expansion, menaing the machine(s) using the VG' need to be turned off or disconnected to do that.

We're releasing online expansion in AOS 5.0, which is due out this month, which will work exactly like you'd expect it to, very easy stuff.

can we use below command to expand the disk in volume group without losing the existing data.

Hi Jon ,

Thank you very much.We are able to detach iscsi initiator for the volume group containing vdisk and and expand the vdisk using acli command and then attach the iscsi initiator back to the volume group.
