Jay, You are fine. You can't change the MTU of a L3 VLAN interface and don't need to. Setting the ports is enough.

Hello Jay, we do nat have experience with S-series, but I'll try to guve my three cents... There ist a command "set mtu {enable | disable}": Enables or disables path MTU discovery protocol. Did you try "set mtu enable" (should be enabled by default)? Did you set all ports, which are belonging to this vlan, to jumbo? Or are some l2 ports belonging to this vlan left with default mtu? Which mtu do you see on issueing a "show interface" command?
