I use LVM and iSCSI to export my device:
LVM for Striping (because ctl needs it), iSCSI for transport.
i created a volume "testserver":
[root@fedorapnfs2 server]# pvs
PV VG Fmt Attr PSize PFree
/dev/sda3 vg_createfedora lvm2 a-- 19.50g 0
/dev/sdb1 testserver lvm2 a-- 2.00g 508.00m
/dev/sdc1 testserver lvm2 a-- 2.00g 508.00m
[root@fedorapnfs2 server]# dmsetup ls --target striped
testserver-share (253, 2)
[root@fedorapnfs2 server]# dmsetup table
vg_createfedora-lv_swap: 0 4128768 linear 8:3 2048
vg_createfedora-lv_root: 0 36765696 linear 8:3 4130816
testserver-share: 0 6291456 striped 2 128 8:17 2048 8:33 2048
The following output is from my iSCSI-targets which i export:
[root@fedorapnfs2 server]# tgtadm --lld iscsi --mode target --op show
