Hi,

Is the iSCSI domain that supposed to be connected through the bond the
current master domain?

No, it isn't. An NFS share is the master domain.


Also, can you please provide the output of 'iscsiadm -m session -P3' ?

Yes, of course (meanwhile I have switched to 2 targets, 1 per portal). This is _without_ iSCSI-Bond:
