Hi all, 

 

I'm seeing a ton of random kernel: blk_update_request: I/O error in my logs.

I just added a new drive that is Pre-Clearing disk: sdy to replace the missing Disk 12.

 

Anyone know why it could be getting these alerts?

That is from an Intel SSD, the other one is having similar issues, probably just noise but if nothing else is spamming the log, try connecting them on a different controller, ideally the onboard Intel SATA ports.

Could this be a power problem?

It might be worth checking the power cable and any splitters.

No splitters, and all powered by a backplane, and directly attached to molex.

But maybe I'll shut it down and give them all a wiggle and make sure its cleanly in still.

 

We did have some poweroutages a week or two ago, but server is on UPS and was shut down cleanly. 

Unlikely to be a connection problem since it's happening to only the 2 Intel SSDs of the same model, but not impossible, still suspect they don't like that controller.
