1812 Posted January 13, 2018 Share Posted January 13, 2018 (edited) 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 Edited January 13, 2018 by 1812 1 Quote Link to comment
keymaster Posted April 4, 2018 Share Posted April 4, 2018 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 K Quote Link to comment
papaj83 Posted April 4, 2018 Share Posted April 4, 2018 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 KI 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) 1 Quote Link to comment
John_M Posted April 4, 2018 Share Posted April 4, 2018 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. 1 Quote Link to comment
