Description Yudhi Widyatama 2014-09-27 02:04:37 UTC

Description of problem:
oo-admin-move failed if the network interface eth0 in the node has no ip address.


Version-Release number of selected component (if applicable):
Openshift Origins v4
rubygem-openshift-origin-msg-broker-mcollective-1.26.1.1-1.el6

How reproducible:
Always on the nodes where eth0 is inactive

Steps to Reproduce:
1. Install openshift origins v4 with 2 or more node hosts with eth1 as the active interface
2. create application 
3. move application using oo-admin-move

Actual results:
Move failed with this error :

DEBUG: Moving content for app '<redacted>', gear '<redacted>' to <redacted>
Identity added: /etc/openshift/rsync_id_rsa (/etc/openshift/rsync_id_rsa)
ssh: Could not resolve hostname : Name or service not known
Agent pid 31683
unset SSH_AUTH_SOCK;
unset SSH_AGENT_PID;
echo Agent pid 31683 killed;
DEBUG: Moving failed.  Rolling back gear '<redacted>' in '<redacted>' with delete on '<redacted>'
Error moving app '<redacted>',platform 'linux', gear '<redacted>' from <redacted> to <redacted>


Expected results:
Gear moved successfully.

Additional info:
Ref : 
https://github.com/openshift/origin-server/blob/master/plugins/msg-broker/mcollective/lib/openshift/mcollective_application_container_proxy.rb#L703

The function get_ip_address hard-codes eth0 as the NIC.

Comment 3 Luke Meyer 2015-02-16 19:53:46 UTC

Being merged, the bug can be tested by QE.

Comment 4 Peter Ruan 2015-02-17 22:26:35 UTC

Does anybody know how to change the eth0 in a devenv?

Comment 5 Luke Meyer 2015-02-18 18:27:52 UTC

I think this should work (in reverse) :
http://minimallinux.blogspot.com/2013/06/centos-6rhel-change-eth1-back-to-eth0.html

Basically:
1. Change eth0 => eth1 in /etc/udev/rules.d/70-persistent-net.rules 
2. mv /etc/sysconfig/network-scripts/ifcfg-eth{0,1}
3. Change eth0 => eth1 in same
4. Reboot (probably cannot just restart network)

Comment 6 Peter Ruan 2015-02-19 06:49:22 UTC

I followed your suggestion, but unfortunately, after reboot, I can't ssh into the devenv.

Comment 7 Aleksandar Kostadinov 2015-02-23 21:24:42 UTC

I managed to get such an instance by executing steps #2 and #3. And the running this one command in root shell:
> ( ifconfig eth0 down; ip link set eth0 name eth1; service network restart; ) &

Comment 8 Miciah Dashiel Butler Masters 2015-09-22 21:42:53 UTC

The proposed fix was shipped in rubygem-openshift-origin-msg-broker-mcollective-1.32.0.1-1.el6op and openshift-origin-msg-node-mcollective-1.29.0.1-1.el6op in RHBA-2015:0220 "Red Hat OpenShift Enterprise 2.2.4 bug fix and enhancement update".  If the fix can be verified, I would like to mark this Bugzilla report CLOSED CURRENTRELEASE.
