My UNRAID server is a HPE microserver gen8 with 16 GB RAM ECC, 1 parity 3 data drives and 1 SSD for cache.

I get those on a few of my HP servers running unRaid. I also ignore them. I looked it up one time a year ago and it said it was fine or something.... or at least, nothing has melted yet!

 

See below for additional info

Hi

My friend is getting exactly the same issue as this with his Microserver gen8, however I have exactly the same server and do not.

Can we please look at a solution for this ?

Many thanks

I have a gen8 microserver as well and get these messages, i did some investigation and its not an Unraid issue, plenty of posts out on the internet around similar messages (buffer size changes from memory). Its basically a bios/firmware issue and which requires an update from HP. Beyond that i didnt look any further as it diesnt affect the server (other than filling the logs)

Tom's reply is the fix I used and it has worked ever since. You just have to exclude the power meter. There is a later BIOS but you can only download it if you're in warranty or presumably if you pay for a service contract which, given the insanely low cost of these things, would be rather pointless. There's no guarantee that if would fix the problem anyway while the sensors-quirk approach does.

 

Hi John

What was Tom's solution and who is Tom please?

Many thanks

Sorry! Tom is limetech. See his reply in the thread that 1812 linked.

Thank you guys
