Disk error but I don't know where

Hi,

I got a disk error, " Device: /dev/da8 [SAT], ATA error count increased from 0 to 1." today but I’m not sure what da8 is, it’s not under my disks.

It doesn’t appear I have permission to attach media, so I can’t add a screenshot. Disks are named, sdj, sdl, sdb, sdk, sdc, sdi, sdd, sdf, sde, sda, sdg, sdh. sdj and sdl are boot, the others are part of the same pool.

In shell if I type “smartctl -a /dev/da8” I get “unable to detect device type please specify device type with -d option”

Running 25.04.2.4, just updated from CORE.

That looks like a leftover alert from CORE, then–Linux doesn’t identify disks that way.

Take the tutorial from the forum bot to fix that.

As for the drive, you will have to check smartctl -a /dev/sdX for all values of X.

Thanks, I’ll clear it and keep an eye out.

Thanks. They look good with the scrutiny app. Is there anything else I should be looking for?

Any error in smartctl -x output, any non-zero value for pending/offline sectors, unrecoverable errors, CRC errors, etc.
