Last night, one of my array drives hit read error and got disabled. SMART looks OK, though I haven't run extended test on it

I see a lot of continuous errors in logs though, so not sure if its just a drive or the controller / cable 

 

Can someone look at attached diagnostics and guide me a bit

ok, I have dug in a bit deeper and seems the noise in the logs may be due to the spindown issue in unraid 7.x. The noise is from the 2 unrelated cache drives, which are SATA SSDs connected to motherboard onboard controller. I've disabled spindown on those, as they are anyway SSDs. Haven't rebooted yet to confirm

 

Now the question is whether I should attempt to rebuild the disabled disk onto itself, to replace it. Assuming I am not overlooking anything

The part where the disk got disabled is missing from the log due to all the spam, reboot and post new diags after array start

rebooted, started array. please see diagnostics after array start

any further suggestions from anyone?

SMART looks fine, and the emulated disk mounted, assuming contents look correct, you can rebuild on top, would recommend replacing cables before to rule that out if it happens again.

 

Log spam is still going on, you should also resolve that.

Thanks. contents look ok. I cannot physically access the server and swap cables right now, but I have started an extended SMART test before doing the rebuild

 

log spam, I am not sure what to do there. But will swap / reseat connections when I open up the server, perhaps over the coming weekend

Extended smart test was ok. Rebuilt on top, which also went fine. Been ok for a day, so all looks ok

 

I'll get to log spam separately when I get a chance
