I think I see where you are going wrong, if I have read this correctly. You are attempting to export an active/active drbd8 block device using iSCSI from both drbd machines at the same time. I suggest the problem with this arrangement is that the iSCSI targets are not happy with sharing a block device. In the same way that you need a clustered filesystem to share a filesystem between machines, you'll need iSCSI target software that's going to be happy with the block device changing underneath it (what with the obvious cache coherence issues). It could be done but I can't see there being much demand for that feature. You could theoretically use the iSCSI targets on top of OCFS2 on top of DRBD8 but I wouldn't recommend it. Stick to the working arrangement of one iSCSI target per block device. Remember KISS etc. -- John P.
