If I understand Stefan correct he was using a recent 3.19-rc kernel, which contains my commit in the subject that stops capping the max_sectors used by the kernel below that which the hardware supports. Given that LIO actually implements the block limits EVPD that suggests we're not properly using that information. Stefant, what does: sg_vpd -p bl /dev/sdX for the LIO device tell? -- 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
