#1886 new defect

[QNAP TR-002] usb reset SuperSpeed device when using -x flag

Reported by: lemonuk Owned by:
Priority: minor Milestone: undecided
Component: all Version:
Keywords: sat Cc:

Description

The spinning drive is connected to QNAP TR-002.
Using the flag -x causes the data read/write transmission to freeze temporarily while the smart test is being performed, then just keeps running normally:

# time smartctl -x -d sat /dev/sdc | grep -i temperature
194 Temperature_Celsius     -O---K   100   100   000    -    35 (Min/Max 14/52)

real    1m1.655s
user    0m0.041s
sys     0m0.004s

dmesg complains about it every time the command is run:

[ 1462.569558] usb 2-5: reset SuperSpeed USB device number 3 using xhci_hcd

Using the -a flag does not cause that issue and is much faster:

# time smartctl -a -d sat /dev/sdc | grep -i temperature
194 Temperature_Celsius     0x0022   100   100   000    Old_age   Always       -       38 (Min/Max 14/52)

real    0m0.113s
user    0m0.026s
sys     0m0.005s

Connecting the drive to StarTech.com SDOCKU33EF is much faster and does not raise any dmesg log even with -x flag:

# time smartctl -x -d sat /dev/sdc | grep -i temperature

Happens also on Ubuntu 24.04 with kernel 6.8.0-45-generic x86_64:

time smartctl -x -d sat /dev/sdc | grep -i temperature
194 Temperature_Celsius     -O---K   100   100   000    -    33 (Min/Max 14/52)

-x is the same as:
-H -i -g all -g wcreorder -c -A -f brief -l xerror,error -l xselftest,selftest -l selective -l directory -l scttemp -l scterc -l devstat -l defects -l sataphy

Please try which of the options trigger the problem. The usual suspects are the commands using SCT protocol which requires WRITE SMART LOG: -g wcreorder -l scttemp -l scterc.

I've found that it's not even necessary to have any file transfer, the command just locks the terminal until the operation is performed, and can't be cancelled with control+c.

The culprit is only -l devstat:

[root@linux ~]# time smartctl -x -d sat /dev/sdc | grep -i temperature
