Docker commands frozen on an openshift node

Solution Unverified - Updated -


  • Docker got frozen on the node. All "docker" commands were waiting forever. -
  • Openshift displayed the node as "NotReady" and all pods went to "Unknown state"
  • systemctl stop docker was also frozen
  • kill on docker processes did nothing
  • kill -9 on docker processes kill most of them but we had some processes (mainly "du" commands) which were not possible to kill
  • docker command was still frozen after killing the processes
