[wiwengweng]

Did it use the ssh service? I also try to enable sshd service and start the service, but again see the last error.

[wiwengweng]

as I ran on, I recreate the cluster again. But still meet some errors.

1. this time ssh is up, but others are not.

⠴ Waiting for DC/OS to startWARNING:retry.api:Command '['docker', 'exec', '--user', 'root', '--interactive', '2669ffd6c3f2633df6fb3be6fad73fd8f5080918f825465e376b48d3b914aa72', '/bin/sh', '-c', 'sudo /opt/mesosphere/bin/dcos-check-runner check node-poststart || sudo /opt/mesosphere/bin/dcos-diagnostics check node-poststart || /opt/mesosphere/bin/3dt --diag']' returned non-zero exit status 127., retrying in 10 seconds...

It means command returned status is not correct. So I log into master node, and check the commands and services.

2. some of the commands does not exist.

[root@dcos-e2e-default-766cf-master-0 bin]# /opt/mesosphere/bin/dcos-diagnostics --verbose check node-poststart
Error: unknown command "check" for "dcos-diagnostics"
Run 'dcos-diagnostics --help' for usage.
unknown command "check" for "dcos-diagnostics"

in fact dcos-diagnostics dose not support check command anymore, and here is the help file.

Usage:
  dcos-diagnostics [flags]
  dcos-diagnostics [command]

Available Commands:
  daemon      Start an http server and polls the components health.
  help        Help about any command

Flags:
      --config string   config file (default is $HOME/.dcos-diagnostics.yaml)
      --diag            Check DC/OS components health.
  -h, --help            help for dcos-diagnostics
      --role string     Set node role
      --verbose         Use verbose debug output.
      --version         Print dcos-diagnostics version

3. 3dt command dose not exist.

[root@dcos-e2e-default-766cf-master-0 bin]#  /opt/mesosphere/bin/3dt --diag
bash: /opt/mesosphere/bin/3dt: No such file or directory

4. key services are not running good.

and these services cannot be restarted using systemctl restart command. Hope someone can help me. TIA

[adamtheturtle]

Thank you @wiwengweng for this thorough bug report.
I appreciate that the logging could be better.

The rough order of operations on the wait command is this:

• Start nodes
• Wait for the SSH service to start up on all nodes (this is what did not work the first time for you, I am unsure why)
• Wait for DC/OS checks to pass

The last of these has to support multiple versions of DC/OS.
It runs multiple commands on each node, to support each version of DC/OS.
Only one of those needs to pass.
It runs those commands on repeat until the services are running well.

The following is a related comment in the code:

    The execution will differ for different version of DC/OS.
    ``dcos-check-runner`` only exists on DC/OS 1.12+. ``dcos-diagnostics
    check node-poststart`` only works on DC/OS 1.10 and 1.11. ``3dt`` only
    exists on DC/OS 1.9. ``node-poststart`` requires ``sudo`` to allow
    reading the CA certificate used by certain checks.

This means that it is not a problem for example that 3dt does not exist on your nodes.

as I ran on, I recreate the cluster again. But still meet some errors.

How long did you wait to see if the services just started up?

[wiwengweng]

thanks for your response, adamtheturtle. I think I have waited for about 30mins+ before I see this error. Then I also try to manually start sshd in all nodes, and be sure they are all alive. But still see some services are "down/auto restart" state in my master container.
