[smartmontools-support] Avoid Repeated messages form smartd

[Carsten Schmitz]

Hi,

everday I am getting this message.

--------------- snip --------------------

This message was generated by the smartd daemon running on:

    host name:  xxx
    DNS domain: xxx.x

The following warning/error was logged by the smartd daemon:

Device: /dev/sda [SAT], 630 Offline uncorrectable sectors

Device info:
HGST HUS726020ALA610, S/N:K5H3M1HA, WWN:5-000cca-25ecfbc1f, FW:A5GNT920, 2.00 TB

For details see host's SYSLOG.

You can also use the smartctl utility for further investigation.

Another message will be sent in 24 hours if the problem persists.
--------------- snap ------------------

When I look at the smartclt output I can see the value also as RAW value, but the SMART count did not degrade

-----------------------------------------

My questions are:

How serious is this error? The number of Offline_Uncorrectable seems to 
be stable right now.

Why isn't the SMART value decreasing and still at 100? (I assume it is 
because the damage is still very small).

If it is not critical to swap this disc right now, how can I prevent 
that I get the notification from smartd every day? Basically I only want 
to be notified when the values are changing, again.

Thank you in advance for any insight you might be able to give. Please 
let me know if you have any questions.

Best regards

Carsten
