Read error on Disk and lots of them - Is it normal?

Hi,

We get the following messages almost every day. The messages below is from november and we get them every month.

Some of these disks has been manually replaced. None of them has been failed automatically by the system. In june we had a few of these messages and then those disks was autofailed.

Is it normal with so many messages on the same disks? It makes me worried about loosing the whole aggregate.

Should we prefail them and call Netapp for replacements?

This is on two DS4243 and 8% of the disks has been replaced. 16% of the disks show these errors.

The system is a FAS3210 running 8.1.2P4

Re: Read error on Disk and lots of them - Is it normal?

That is not normal, and I would be concerned as well.  Have any of the drives you've replaced started showing errors again?  Is it possible something's happened to the system that might have degraded the drives?  The only time I've seen something similar is when our datacenter cooling went out, and we didn't have any temperature sensors.  We got it fixed, but 2-3 months later we were losing a couple drives a week.

I would work with NetApp to see if they will replace the erroring drives.

Re: Read error on Disk and lots of them - Is it normal?

The system has been in operation for 18+ months or more and until this summer no drives has been replaced. The DC where the system is located has been stable and hasn't had an outage or temperature variation since we started using their services so Im at a loss the explain why the drives suddenly are starting to fail. We do have another controller (same FAS3210) with the same kind of shelf DS4243 and the same type of disks which hasen't shown any problems. Its only the controller that runs our VMware farm that has these errors. The VMware controller probably has more load on it than the CIFS controller so maybe this is related to the load?

According to NetApp they wont replace the drives unless they have failed. We had one drive that failed this summer and it took almost 24 hours until the rebuild finished due to timeouts which caused our customers some pain and thats why we now like to prefail the drives. However since yesterday NetApp wont let us do that anymore and hasn't come up with an plausible explanation why this happens.

Re: Read error on Disk and lots of them - Is it normal?

Have any of the drives that have been replaced started showing errors?  If so, then I would be more likely to suspect something environmental.  Higher load is possible, but I wouldn't really expect it.  I'm assuming the drive firmware is up to date and matches the other controller?  Maybe it's worth getting the serials of the failing drives and see if you can research whether there was a bad production run or something?

NetApp's response seems typical from first or second level.  You might try working with your SE to try to escalate the issue from the inside.  At one point we had a NetApp person dedicated to fielding customer concerns just like this one - can't remember what his title was, but you probably have one as well.  Point out that you've got an abnormal failure rate that is hurting your customers, and therefore you.  Might not hurt to hint that there are other NAS vendors out there....

Re: Read error on Disk and lots of them - Is it normal?

None of the replaced drives has started showing errors yet.

I have a hard time imaging it could be something environmental since its in a monitored DC which hasn't had any problems yet.

All the drives were bought at the same time so they could possibly be all from the same batch. I'll try and see if I can find the serials of those that failed and see if they all are close.

And I'll give Netapp another call and hear what they have to say.

The frequency of the errors also seem to go up. This is from september until today for one of the bad disks which hasen't failed yet.
