My Question:

Is it time to pick my cold spare HDD from the shelf and replace the 3rd disk in the RAID5 ?

root@antnas:~ # cat /etc/version
FreeNAS-11.3-U4.1 (66add776a2)

HP Microserver N36L (oldschool :) )

Thank you

Well it could be a single occurrence. Apart from the one failed test (and the newer one running successful)
the SMART data looks quite OK. (BTW, readability is much better with [CODE][/CODE] tags).

On the other hand, your HDD has a total runtime of over 10 years. And this even on a WD green,
which are according to the manufacturer not meant for 24/7 usage.

So it might be a good idea to think about replacing the HDD anyway.

Thank you Fredda

i am greatful for your experience
i couldnt understand that so good
the error repeats every night in the email so i guess i will power it down and do what you recommended.

this disk is for 2 years on the cold shelf and it will be happy to be used
i will have to order a new spare ;)

have a good day

You get the email, because the 2 errors are still shown. They'll be cleared if you issue a zpool clear command.
After that you should not get mails anymore, unless the error shows up again.

That said, I this it's still a good idea to replace a HDD after 10 years.
