[smartmontools-support] longtime for extended self-test and status where it is at

[shirish शिरीष]

Hi all,

I have a 2 TB external USB bus-powered hdd. A Seagate ST2000LM003
HN-M201RAD which is also used by Samsung now as Seagate bought
Samsung some years ago.

I tried -c to figure out how much time it will take to do the extended
self-test and it shows -

# smartctl -c /dev/sdb
smartctl 6.6 2016-05-31 r4324 [x86_64-linux-4.6.0-1-amd64] (local build)

=== START OF READ SMART DATA SECTION ===
General SMART Values:
Offline data collection status: (0x00) Offline data collection activity
was never started.
Auto Offline Data Collection: Disabled.
Self-test execution status: ( 38) The self-test routine was interrupted
by the host with a hard or soft reset.
Total time to complete Offline
data collection: (22380) seconds.
Offline data collection
capabilities: (0x5b) SMART execute Offline immediate.
Auto Offline data collection on/off support.
Suspend Offline collection upon new
command.
Offline surface scan supported.
Self-test supported.
No Conveyance Self-test supported.
Selective Self-test supported.
SMART capabilities: (0x0003) Saves SMART data before entering
power-saving mode.
Supports SMART auto save timer.
Error logging capability: (0x01) Error logging supported.
General Purpose Logging supported.
Short self-test routine
recommended polling time: ( 1) minutes.
Extended self-test routine
recommended polling time: ( 373) minutes.
SCT capabilities: (0x003f) SCT Status supported.
SCT Error Recovery Control supported.
SCT Feature Control supported.
SCT Data Table supported.


Which basically comes down to 6.5 hours or thereabouts. While this I
can do this it would be nice if there was a way to check the progress
once in a while.

During an offline test, the progress is reported by the above "Self-test
execution status" in 10% steps. The smartd daemon logs this info if -l
selfteststs is enabled.

Do not use --captive.

Be aware that the USB bridge may abort the test if the drive is not
accessed frequently, see:
