I have iscsi NAS with 2 x 2TB drives in one logical volume on the target server.

VG #PV #LV #SN Attr VSize VFree
iscsi 2 1 0 wz--n- 3.63t 0

LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert
nas iscsi -wi-ao---- 3.63t

When I do 'df -h' on the initiator server, It shows 3.8G being used.

Filesystem Size Used Avail Use% Mounted on
/dev/sdc 3.7T 3.8G 3.7T 1% /iscsi-nas

This drive was freshly formatted with XFS.. why does it show this space being used when nothing is on it?
