  • Ticket #971 – Description

    initial v1  
    66
    77With UAS enabled I can see info with -d scsi (-d sat{,12} doesn't work), but SMART info is not available:
     8{{{
    89 # smartctl -d scsi -i /dev/sdb
    910smartctl 6.6 2017-11-05 r4594 [x86_64-linux-4.14.15-1-ARCH] (local build)
    … …  
    2425Local Time is:        Sun Jan 28 11:28:14 2018 WET
    2526SMART support is:     Unavailable - device lacks SMART capability.
     27}}}
    2628
    2729If I blacklist UAS, then I get from smartctl:
     30{{{
    2831 # smartctl -i  /dev/sdb
    2932smartctl 6.6 2017-11-05 r4594 [x86_64-linux-4.14.15-1-ARCH] (local build)
    … …  
    4649SMART support is: Available - device has SMART capability.
    4750SMART support is: Enabled
     51}}}
    4852
    4953I wonder if it's possible to get SMART access without blacklisting UAS. I don't like the "very big device" messages I receive in dmesg and I guess the device will perform better with UAS enabled (Kernel 4.14.15-1 from Archlinux X86_64).
