Comment 1 Abhishek Gupta 2013-08-15 18:41:59 EDT
Can you please provide the broker, mcollective and platform (node) logs for a request that fails with this error?
Comment 3 Abhishek Gupta 2013-08-19 16:59:40 EDT
Providing snippets of logs from the broker and mcollective in the previous comment. Seems like useradd is failing because it is unable to lock /etc/passwd .
Comment 4 Mrunal Patel 2013-08-19 17:13:03 EDT
Most likely some of these files were left behind by a crashing useradd/userdel operation.

Comment 5 Mrunal Patel 2013-09-04 15:42:42 EDT
Have we seen this issue again in PROD?

Comment 6 Thomas Wiest 2013-09-05 12:10:18 EDT
We've changed how we're doing these creates now.

We're now using the --from-code method of creating a drupal quickstart.

So, no, we're no longer seeing this problem, but I don't know if that's because it's fixed or because we changed how we're doing the creates.
Comment 7 Mrunal Patel 2013-09-10 15:28:24 EDT
Lowering severity for now since we haven't been able to root cause it looking at the logs and also we haven't seen it again. It will be easier to debug, if we can inspect the nodes if/when the issue is seen.
Comment 8 Dan Trainor 2013-09-24 20:55:34 EDT
Hey Thomas, I'm at a client site right now and they've encountered this.

Can you please tell me more information about in which component this --from-code method was changed in?  I'd like to settle this one.  I've attached a full stack trace in the hopes it helps.

Comment 10 Mrunal Patel 2014-02-10 18:34:10 EST
Dan Trainor,
Did you see any of these files when the issue occured? 

If so, do you have timestamps so we can correlate with the node call?
Comment 11 Jhon Honce 2014-04-14 19:21:18 EDT
The message "Cannot validate input uid: value should be a number" is being emitted from the MCollective client on the Broker when attempting to query a Node.  From the openshift.ddl, 

action "has_uid_or_gid", :description => "Returns whether this system has already taken the uid or gid" do
    display :always

    input :uid,
        :prompt         => "uid/gid",
        :description    => "uid/gid",
        :type           => :number,
        :optional       => false

mcollective_application_container_proxy.rb#has_uid_or_gid? is populating +uid+ with some value that is not considered :numeric by MCollective validators.
