Description: Container <container> is permanently down on node <node>

Oorzaak

The container stopped or paused or not started at all for at least 10 minutes.

Oplossing

Docker containers (object-main, fabric-lifecycle, fabric-zookeeper, fabric-registry) stopped or paused or not started at all for at least 10 minutes. Use the following procedure to determine the failing container:
  1. Based on Component ID or Node ID determine the node in the ECS cluster which registered the failure. Example: Component ID
4ca42022-46ed-475e-8ab7-6ef9141e5415
sudo /opt/emc/caspian/fabric/cli/bin/fcli lifecycle node.network --id 4ca42022-46ed-475e-8ab7-6ef9141e5415
{
  "network": {
    "hostname": "hostname.domainname.net",  << Hostname
    "private_ip": "169.254.1.3",       << NAN IP
    "mgmt_ip": "10.2.3.4",     << Management IP 
    "public_ip": "10.241.207.59",
    "data_ip": "10.241.207.73",
    "replication_ip": "10.241.207.59",
    "public_interface_name": "public",
    "private_interface_name": "private.4",
    "mgmt_interface_name": "public",
    "data_interface_name": "public:data",
    "replication_interface_name": "public"
  },
  "status": "OK",
  "etag": 50
}
  1.  ssh to the target node using management IP, private IP, or hostname.
 
  1. Verify that the docker server is operational with proper parameters
# ps -ef | grep docker
root      50062      1  0 Jun02 ?        00:02:11 /usr/bin/docker daemon -H fd:// --insecure-registry=0.0.0.0/0 --log-level=warn
  1. Next we have to validate which container (NAMES Column) was stopped or not started at all for some reason (look at STATUS column):
# sudo docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED                STATUS              PORTS               NAMES
7bf16df0ef15        464b97154c24        "/opt/vipr/boot/boot."   3 days ago          Up 3 days                                    object-main
0ef5cc422543        24d9d6008893        "./boot.sh lifecycle"    3 days ago          Up 3 days                                    fabric-lifecycle
87d6c77d98ca        32cce433c3dc        "./boot.sh 3 1=169.25"   3 days ago          Up 3 days                                    fabric-zookeeper
  1. Verify that the fabric service is running. Fabric agent attempts to revive problem container automatically
# sudo service fabric-agent status
fabric-agent.service - fabric agent
   Loaded: loaded (/usr/lib/systemd/system/fabric-agent.service; enabled)
   Active: active (running) since Thu 2016-06-02 17:56:39 UTC; 3 days ago
  Process: 50643 ExecStartPre=/bin/rm -f /var/run/fabric-agent.pid (code=exited, status=0/SUCCESS)
 Main PID: 50645 (java)
   CGroup: /system.slice/fabric-agent.service
  1. View the stopped/failed container status 
# sudo docker inspect fabric-zookeeper | grep -A12 State
    "State": {
        "Status": "running",
        "Running": true,
        "Paused": false,
        "Restarting": false,
        "OOMKilled": false,
        "Dead": false,
        "Pid": 80462,
        "ExitCode": 0,
        "Error": "",
        "StartedAt": "2016-06-06T17:29:12.968133861Z",
        "FinishedAt": "2016-06-06T17:29:12.882812946Z"
    },
