No my question, what should I do next? This drive is about a year old, and after my big move, all was fine in a long test. Nothing happend to the server, it is just running.
Any help -> Appreciated :)

Do you need my system specs? Please look to my signature ;)

I have made another test, now without errors? :O

When I looked at the timing, the only thing I could eventually imagine, that a microwave caused the problem. Due to some issues of space, the server is in my kitchen, in a big metal Nanoxia Deep Silence 6 Rev.B.
About 50cm near to it, there is my microwave. Could this be the reason? If yes, if need to move that damn thing :/
Funny, but it should not https://www.reddit.com/r/pcmasterra..._there_risks_in_keeping_your_computer_near_a/.

If it was out of warranty, I would probably wait and watch it. But since you have two read failures fairly close to each other, there is a good chance it will worsen over time. Microwave probably not related. Scrubs are clean?

If it's in warranty, RMA it. If not, do a full read of the entire drive (dd if=/dev/da5 of=/dev/null bs=1m) and see if any of the error counters increase. If not, keep a close eye on it. If yes, get a replacement on order. :)

And I have requested an RMA at WD. Do you know how long this needs? Because I have no idea if I should run my server with 1 disk less, or not....
So this could take up two two weeks.
So what I first do is a full backup. But I do not know if I should risk a scrub now.

If you request an advance RMA (which you could do with WD last time I needed to return a drive), you don't have to be without a drive at all. Get the new drive, burn it in, replace the old one, then send back the old one.

Hi danb35,
thanks for your answer.
Unfortunately I have requested the RMA yesterday as a "Standard RMA". I saw that I could request an advanced one, but when I read through everything with Creditcard and so one, I have choosen the Standard one. I do not know if I could change it now from Standard to advanced.
If this is not possible I have two options:
1. let the pool run in degraded mode for 2 weeks (RAIDZ2)
2. Replace the WD red temporary with a desktop WD Green

What would you guys do?
Thank you!

Your pool shouldn't be degraded right now, so there is no problem with waiting two weeks. Even if it was degraded, there is no problem waiting two weeks as long as you scrub more often than never.

Hi there,

so last week I have sent the drive to WD for RMA. Even today, thanks to DHL, the drive/paket has not yet arrived at WD.
I have powered down my NAS and still waiting for the drive...
Unless this process can take forever, I think about buying a new one instead. Also it can happen that I get a refurbished one back from WD, maybe its not the best idea to run a refurbished one in FN 24/7.
But maybe I get a new one back, who knows?
Any kind of experience with that?
Should I buy a new one and let the replacement drive acting as a cold spare?

Thanks,
Ice

Burn the replacement in before you put it in service to make sure its ok to add to your pool.
