Filesystems not unmounted cleanly on service stop


(Sweharris) #1

CentOS 7.4 based. Standalone node running UCP; it used to be a cluster master but the worker nodes had been removed. All the standard services were running, but no “customer” workloads.

I then ran
sudo systemctl stop docker
and the system shutdown fine.

Except some filesystems, all related to k8s, were not unmounted
