https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=223381 --- Comment #5 from Jim D. <randomnoise058@gmail.com> --- I have found the problmematical commands on the VBox FBSD-11.1 client host which invoke the previously noted "kernel WARNING/iSCSI underflow" messages: smartctl -d scsi -a -T permissive /dev/da3 smartctl -d scsi -A -T permissive /dev/da3 Same effect if "-d scsi" is not included. "smartctl --scan-open" reports da3 as "scsi" device type which is one of the 3 attached iSCSI Targets. Interestingly enough, the following smartctl commands from FBSD-11.1 host do NOT cause any kernel messages: smartctl -d scsi -H -T permissive /dev/da3 smartctl -d scsi -i -T permissive /dev/da3 Installed FBSD-11.1 smartmontools is at version 6.5 2016-05-07. It might be that the Synology SAN handling of the smartctl request for SAN HDD smartmon attributes from the installed SAN hard drive is problematical, but I don't understand why that would cause FBSD iSCSI underflow messages. ========================== Results from Synology SAN same as obtained from FBSD-11.1 host ========================== smartctl --scan-open /dev/hda -d ata # /dev/hda, ATA device /dev/sda -d scsi # /dev/sda, SCSI device -------------------------------- smartctl -d scsi -i -T permissive /dev/sda smartctl 6.5 (build date Oct 25 2017) [x86_64-linux-3.10.102] (local build) Copyright (C) 2002-16, Bruce Allen, Christian Franke, www.smartmontools.org === START OF INFORMATION SECTION === Vendor: WDC Product: WD6000HLHX-01JJP Revision: 04.0 User Capacity: 600,127,266,816 bytes [600 GB] Logical block size: 512 bytes LU is fully provisioned Rotation Rate: 10000 rpm Logical Unit id: 0x50014ee0ae06dfb2 Serial number: WD-WX71E71WZ063 Device type: disk Local Time is: Sat Nov 18 01:13:52 2017 CST SMART support is: Unavailable - device lacks SMART capability. -------------------------------- smartctl -d scsi -a -T permissive /dev/sda smartctl 6.5 (build date Oct 25 2017) [x86_64-linux-3.10.102] (local build) Copyright (C) 2002-16, Bruce Allen, Christian Franke, www.smartmontools.org === START OF INFORMATION SECTION === Vendor: WDC Product: WD6000HLHX-01JJP Revision: 04.0 User Capacity: 600,127,266,816 bytes [600 GB] Logical block size: 512 bytes LU is fully provisioned Rotation Rate: 10000 rpm Logical Unit id: 0x50014ee0ae06dfb2 Serial number: WD-WX71E71WZ063 Device type: disk Local Time is: Sat Nov 18 01:16:00 2017 CST SMART support is: Unavailable - device lacks SMART capability. === START OF READ SMART DATA SECTION === Current Drive Temperature: 0 C Drive Trip Temperature: 0 C Error Counter logging not supported [GLTSD (Global Logging Target Save Disable) set.
