Good morning.
Today I woke up to the following emails from my NAS:
Device: /dev/sdb [SAT], FAILED SMART self-check. BACK UP DATA NOW!.
and
Device: /dev/sdb [SAT], Failed SMART usage Attribute: 45 Unknown_Attribute..
However, after a hour or so from happening I go to work and remotely smartctl -a the disk, to this:

Selective self-test flags (0x0):
After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.
The above only provides legacy SMART information - try 'smartctl -x' for more
Ok, 22 is helium levels… What is 45 tho? And why it is not failing anymore?
Should I replace it? Pool is 8wide raidz-2 and never got degraded. Seems like it went to normal levels on its own.
All disks are used enterprise disks, HC520.

Short SMART tests are of limited use. Run a long test
sudo smartctl -t long /dev/sdb
and then check
sudo smartctl -x /dev/sdb
To know what this means, contact HGST technical support. But any error should be a ground for RMA.

80% remaining on the long test since I launched it last time I posted 
I guess we’ll have to wait
