October 12, 20232 yr Hi, i have the problem that my unraid server becomes really unresponsive from time to time. The Processor view often shows all cores to be used by nearly 100%: But when i look into htop everything seems to be fine: I've ran Proxmox before on this server where i had no performance issues at all. Does anyone know what could cause this? Is it just caused by parity calculations? If thats the case, why can't i see them in htop or somewhere else? My system currently: OptiPlex 7070 Intel(R) Core(TM) i5-9500 32GB Ram DDR4 WD Blue SN570 2TB (Parity) Crucial BX500 2 TB (Disk) 18 Docker containers 2 Users Thank you
October 13, 20232 yr Author Seems like it does. I've deactivated docker now in Settings -> Docker. After that the usage pretty much goes to zero. What could cause this?
October 13, 20232 yr Community Expert Start the containers one by one to see if you can find the culprit.
October 13, 20232 yr Author Okay, all containers are now stopped and i've started one of the smallest containers i have (homarr) The Usage immediately jumps up to 50%. Just for a short time but multiply this by 18 and it makes sense that there is such a high usage. But why is it like this? Under Proxmox with all containers enabled there were no performance issues at all. Even when i open the webpage of homarr in my browser i can see that there is a significant increase in usage in this graph.
October 13, 20232 yr Community Expert If you are using /mnt/user paths try with disk shares, or use an exclusive share.
October 13, 20232 yr Author I think i found the problem. I moved the docker directory to a dedicated pool drive. Now this is not part of the array anymore and it runs fine
October 13, 20232 yr Community Expert Solution Yeah, docker in the array will be super slow, docker on a pool can still be faster with disk or exclusive shares if you find it slow.
