Which docker rpm is installed on this system? docker.x86_64 1.10.3-46.el7.8 Moving to kubernetes because I doubt it's a docker issue (other than the fact that https://bugzilla.redhat.com/show_bug.cgi?id=1362109 corrupted the thin pool and Docker can't start). Given the corrupted lvm, the kubelet would have no way of acknowledging the container as dead unless the docker daemon itself was restarted (which it could not because of the lvm). I am marking this as a duplicate of the original issue: 1362109 *** This bug has been marked as a duplicate of bug 1362109 *** |
Created attachment 1187572 [details] docker logs Description of problem: Ran a master vertical on 300 node cluster with 1000 projects. While deleting the projects one of the pods got stuck in Terminating state.
