Question: I get an email about the same SMART error every day. I’d like to configure the SMART daemon to ignore this specific error, but only this, since I still want to now if anything changes or gets worse.
This email was generated by the smartd daemon running on: host name: jonDNS domain: [Unknown]NIS domain: (none)The following warning/error was logged by the smartd daemon:Device: /dev/sdb [SAT], 11 Currently unreadable (pending) sectorsFor details see host’s SYSLOG.You can also use the smartctl utility for further investigation.The original email about this issue was sent at Sun Nov 25 02:30:45 2012 CETAnother email message will be sent in 24 hours if the problem persists.
When this first happened, the number of unreadable sectors was slowly increasing, so made a backup and tried many things described in this thread:https://serverfault.com/questions/104417/how-do-i-easily-repair-a-single-unreadable-block-on-a-linux-disk
As you can see from the email, this was 1.5 years ago, so I don’t exactly remember what I tried and what not. However, the disk remains stable and working since then, so I don’t see any reason to change anything. (Yes, I regularly create backups.)
I can only think of a workaround, which would be to ignore all mails containing this exact text, but this would only be treating symptoms, not the cause.
Edit:
I know many or most of you will give me the “replace the disk” advice, which in general is the best possible advice for a question like “I get this error, what should I do?”
But please, please accept that I’m aware of the risk and asking a very specific question regarding the SMART daemon. I didn’t find anything in the docs that would indicate it is possible to do what I want, but I wanted to double check here first before going with my workaround.
Update:
About a week ago, the counter went down to 1 again. I have no idea what caused this, I did not maintenance work whatsoever on that machine. After more than 2 years, 11 sectors just got okay again. This is really weird.
Answer: you need change config /etc/smartd.conf
add arguments to you setting:
-t -I 197 ?
It ignore attribute 197 – Pending Sectors
like this(Example):
/dev/ad0 -H -l error -l selftest -t -I 197
