All physical hosts, Original problem was detected on qlogic FC HBA (Ubuntu 16.04) To check if this is transport related, we reproduced the 0 byte corruption on iSCSI too. To check if the problem is our user space tool we ran with with iSCSI + tcpdump and learnt that the problem is probably in the kernel and is not related to the transport selected. Later to learn more I ran "sg_mmap_read" on several devices: local hard disks, FC cards and iSCSI. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
