Nom Nom Nom

Regretfully not burger related – but related to an error (I think) in the upgrade of  Ubuntu 14.10 Utopic from 15.04.

In trying to figure out what it was that was causing iowait of 50% on an otherwise idle box, I was checking over processes with a fine toothed comb.

I discovered that for some reason the grub menu had launched with the same (unfamiliar) modules a lot of times.

This was teh reason why it sat in the process list thus….

/sbin/init nomdmonddf nomdmonisw nomdmonddf nomdmonisw nomdmonddf nomdmonisw

Removing this previously unnoticed command from the boot sequence ended in badness.

Adding it back just the once resulted in the following….

/sbin/init nomdmonddf nomdmonisw

My understanding it is related to dmraid and mdadm. As this is a software RAID1 installation that would add up – but three times – really?
