CoreOS VM crash: swap trace printed
I'm using CoreOS 773.1.0 with kubernetes. Recently it crashes and printed this trace log:
The VM is still running but I cannot ssh to it, kubernetes master node declare it as NotReady. I had to turn it off (not shutdown) and start it.
I'm using Hyper-V as hypervisor, the VM is assiged 12GB RAM, 4GB swap, 4 cores CPU. Especially, I got this error after I moved the disk (.vhd file) to new partition.
Solution
This is a known issue to CoreOS 717.3.0 with swap: https://github.com/coreos/bugs/issues/429
