Synology marks a hdd as critical (self.synology)

Hi all,

I recent times my ds918 is marking a hdd as critical because it went to a full identification cycle. It only failed once and smart attributes, including the long ones, are always showing a healthy hdd.

The point is that synology is re issuing the alert every day and I cannot manually mark it as no problematic.

So, how seriously should I take this warning and if there is any way to reset this status once for all????

Regards

What kind of drive is it? There's a chance the alert could be legitimate.

It is a wd Red Serie hdd.

And this is the exactly the point. The hdd is not showing any reduction in performance. Smart info is solid healthy. Btrfs does not show any crc error and also there are not retries in transaction.

The question was more if this alert could be a glitch of synology and in that case hwi to reset it.

Have you had your drive(s) for a while? Could be WDDA throwing up the warning. See this video if you haven't already https://youtu.be/jx4i64uqsIA?si=BbV1GGCL6GRJ3VM8

I have a zero tolerance for any indications of issues. If a drive so much as sneezes weirdly I’ll replace it straight away. Why? Well, I’ve put my important shit on that array so why fuck around?

The question is more if this could be more a glitch in synology than a real error.

As a said before, I was not able to find any other indicator of problems. Smart is good (not a single error), performance is solid, etc etc

Are your drives about three years old?

In my experience. If a drive has any failure it will have more. Replace it ASAP.
