Okay, I wasn't reading carefully... Try this: dd if=/dev/zero of=disk3 count=1 bs=1 skip=50G
That will give you a 50GB thin-provisioned file for iSCSI.

This will essentially thin-provision your iSCSI volume file. I use this method to make iSCSI volumes that live on gluster.

And I am doing the similar way as http://www.gluster.org/community/documentation/index.php/GlusterFS_iSCSI It works well, but in the process of dd if=/dev/zero of=disk3 bs=2G count=25 it needs long time as for my storage volume is around 1TB. I have one question about whether there is some way to make gluster volume can be exported as an iScsi target without creating disk files? For iscsi, it support both disk file and logical unit like /dev/sdb1, but it seems it could not support normal folder like the mount folder from glusterFS. Can anybody kindly advise?
