Hello Igor, hello Niklas,
on my NAS I am encountering the following issue since v6.6.44 (LTS), when executing the hdparm command for my WD-WCC7K4NLX884 drives to get the active or standby state:
$ hdparm -C /dev/sda /dev/sda: SG_IO: bad/missing sense data, sb[]: f0 00 01 00 50 40 ff 0a 00 00 78 00 00 1d 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 drive state is: unknown
While the expected output is the following:
$ hdparm -C /dev/sda /dev/sda: drive state is: active/idle
I did a bisection within the stable series and found the following commit to be the first bad one:
28ab9769117c ("ata: libata-scsi: Honor the D_SENSE bit for CK_COND=1 and no error")
According to kernel.dance the same commit was also backported to the v6.10.3 and v6.1.103 stable kernels and I could not find any commit or pending patch with a "Fixes:" tag for the offending commit.
So far I have not been able to test with the mainline kernel as this is a remote device which I couldn't rescue in case of a boot failure. Also just for transparency it does have the out of tree ZFS module loaded, but AFAIU this shouldn't be an issue here, as the commit seems clearly related to the error. If needed I can test with an untainted mainline kernel on Friday when I'm near the device.
I have attached the output of hdparm -I below and would be happy to provide further debug information or test patches.
Cheers, Christian
