https://bugzilla.kernel.org/show_bug.cgi?id=205107 --- Comment #19 from Alexis Murzeau (amubtdx@xxxxxxxxx) --- I've done these tests (see attachment harddisk_shutdown_tests_wd_elements_linux_5.9.tar.gz): - Powerup the computer without the hard disk connected - When in grub, at the same time as chossing Linux, connect the USB cable to the computer - Wait console login prompt - Login as root, dump SMART data in "linux_harddrive_shutdown_smartdump1" - Power off the computer using "poweroff" command a root - The harddisk will emit a clearly ear-able "clic" sound - While the computer if OFF, unplug the hard disk (which is not powered anymore because the computer is OFF) - Powerup the computer - Boot Linux - Wait console login prompt - Login as root - Plug the hard drive - Dump SMART data in "linux_harddrive_shutdown_smartdump2_after_plug_while_kernelboot" - These SMART fields were incremented (beside Spin_Up_Time which changed too but is probably unrelated to this issue): - Start_Stop_Count - Power_Cycle_Count - Power-Off_Retract_Count - Load_Cycle_Count - Power off the computer using "poweroff" command a root - The harddisk does not emit any clic sound when the computer powers off, and just spin down - While the computer if OFF, unplug the hard disk (which is not powered anymore because the computer is OFF) - Powerup the computer - Boot Linux - Wait console login prompt - Login as root - Plug the hard drive - Dump SMART data in "linux_harddrive_shutdown_smartdump3_after_plug_after_console_login" - No SMART field was changed - Power off the computer using "poweroff" command a root - The harddisk does not emit any clic sound when the computer powers off, and just spin down - While the computer if OFF, unplug the hard disk (which is not powered anymore because the computer is OFF) - Powerup the computer - Boot Linux - Wait console login prompt - Login as root - Plug the hard drive (same test as previous boot) - Dump SMART data in "linux_harddrive_shutdown_smartdump4_after_plug_after_console_login" - No SMART field was changed beside Spin_Up_Time - Spin down the hard drive using this command: "udisksctl power-off -b /dev/sdb" - The hard disk spin down as expected - Unplug the hard disk - Plug the hard disk again - Dump SMART data in "linux_harddrive_shutdown_smartdump5_after_udiskctl_poweroff" - These SMART fields were incremented beside Spin_Up_Time: - Start_Stop_Count - Power_Cycle_Count - Load_Cycle_Count - Spin down the hard drive using this command: "udisksctl power-off -b /dev/sdb" - The hard disk spin down as expected - Unplug the hard disk - Poweroff the computer - Powerup the computer - When in grub, at the same time as chosing Linux, connect the USB cable to the computer - Wait console login prompt - Login as root - Dump SMART data in "linux_harddrive_shutdown_smartdump6_after_udiskctl_poweroff" - These SMART fields were incremented beside Spin_Up_Time: - Start_Stop_Count - Power_Cycle_Count - Load_Cycle_Count - Run this command with the apropriate path matching the hard disk: - echo 1 > /sys/devices/.../manage_start_stop - Power off the computer using "poweroff" command a root - The harddisk does not emit a "clic" sound - While the computer if OFF, unplug the hard disk (which is not powered anymore because the computer is OFF) - Powerup the computer - Boot Linux - Wait console login prompt - Login as root - Plug the hard drive - Dump SMART data in "linux_harddrive_shutdown_smartdump7_after_plug_before_kernelboot_and_enabling_manage_start_stop" - These SMART fields were incremented (beside Spin_Up_Time): - Start_Stop_Count - Power_Cycle_Count - Load_Cycle_Count - Run this command with the apropriate path matching the hard disk: - echo 1 > /sys/devices/.../manage_start_stop - Power off the computer using "poweroff" command a root - The harddisk does not emit any clic sound when the computer powers off, and just spin down - While the computer if OFF, unplug the hard disk (which is not powered anymore because the computer is OFF) - Powerup the computer - Boot Linux - Wait console login prompt - Login as root - Plug the hard drive - Dump SMART data in "linux_harddrive_shutdown_smartdump8_after_plug_after_console_login_and_enabling_manage_start_stop" - These SMART fields were incremented (beside Spin_Up_Time and Power_On_Hours): - Start_Stop_Count - Power_Cycle_Count - Load_Cycle_Count - Reboot the computer - Boot Windows - Dump SMART data in "linux_harddrive_shutdown_smartdump9_after_windows_boot" (using smartctl for Windows) - These SMART fields were incremented (beside Temperature_Celsius): - Load_Cycle_Count - Shutdown Windows - When the computer is powered off, unplug the hard disk - Powerup the computer - Boot Linux - Wait console login prompt - Login as root - Plug the hard drive - Dump SMART data in "linux_harddrive_shutdown_smartdump10_after_windows_shutdown" - These SMART fields were incremented (beside Spin_Up_Time and Temperature_Celsius): - Start_Stop_Count - Power_Cycle_Count - Load_Cycle_Count [... I've done a failed Windows VM boot test elided here] - Dump SMART data in "linux_harddrive_shutdown_smartdump11_before_windows_VM_test" - On Linux host, modprobe usbmon and start wireshark to capture USB traffic - Boot a Windows VM (using Virtual Box) with USB pass-though for hard disk - Shutdown the Windows VM via its gui - Wait Windows VM to shutdown - Dump SMART data in "linux_harddrive_shutdown_smartdump12_after_windows_VM_shutdown" - These SMART fields were incremented (beside Power_On_Hours): - Load_Cycle_Count - Save USB packet dump summary as "linux_harddrive_shutdown_smartdump12_after_windows_VM_shutdown_usb_capture" keeping only packets while the VM was running - At shutdown, there are only SCSI read/write USB packets (no SCSI spin down command) -- You are receiving this mail because: You are watching the assignee of the bug.
