We have an F330 running 4.3.3D2 where one of the disks is now generating 30 - 40 "READ sector xxxxxxx recovered error" messages per day. At what frequency of such messages should I start worrying about the disk?
Perhaps I am overestimating the severity of this problem, but I start getting nervous if I see *one* warning of that nature per *week*. That is, if I see a single warning in one of the weekly syslog e-mails, I'll start watching that filer more closely. Netapp has been very good about replacing drives and RAM that ONTAP complains about. I figure I don't use up their resources calling their tech support, so I'll take advantage of their hardware warranty. ;-)
All of our production filers are used very heavily, and I don't want to let a drive degrade to the point where ONTAP reports more than one warning a day. Maybe I'm paranoid about failure, but then that's why I have Netapps in the first place. :)
