Smart is reporting the following error each day one one of my data centre server SSDs:
This message was generated by the smartd daemon running on:
host name: x
DNS domain: x
The following warning/error was logged by the smartd daemon:
Device: /dev/sda [SAT], 1 Currently unreadable (pending) sectors
Device info:
INTEL SSDSC2BB480G7, S/N:PHDV701605XT480BGN, WWN:5-5cd2e4-14d60bdf9, FW:N2010101, 480 GB
For details see host's SYSLOG.
You can also use the smartctl utility for further investigation.
The original message about this issue was sent at Tue Feb 6 18:43:41 2018 EST
Another message will be sent in 24 hours if the problem persists.
Syslog, shows no additional information.
I have read elsewhere that I need to perform an extended smart test, then write to the sector specified in the test results to force the drive to mark it as a bad sector and reallocate.
I ran a long test:
sudo smartctl -t long /dev/sda1
But the output of sudo smartctl -a /dev/sda1 says that the test completed without error?

Is there really a problem, and if so how do a diagnose it properly?
