Is it possible to create an ISCSI target on (or connected to) a Linux server, manage it via NSS and NRM, and format it on the initiator machine as NTFS?

If not, the ad hoc pool expansion feature in NSS is what I need, so how might I get that functionality to expand an ISCSI target when space grows short? (without either creating a new partition or wiping the original out, expanding, and restoring).
