yum does not support server failover
Last modified: 2013-01-10 05:17:50 EST
Description of problem: Adding a failover server in /etc/sysconfig/rhn/up2date breaks yum. Something like serverURL=https://myproxerserver.foo.bar/XMLRPC;https://xmlrpc.rhn.redhat.com/XMLRPC; should be allowed but isn't. Version-Release number of selected component (if applicable): yum-3.0.1-5.el5 How reproducible: Add anything more than a single server to the serverURL Steps to Reproduce: 1. Add anything more than a single server to the serverURL 2. run yum 3. look at traceback of explosion Actual results: # yum update Loading "installonlyn" plugin Loading "rhnplugin" plugin Traceback (most recent call last): File "/usr/bin/yum", line 29, in ? yummain.main(sys.argv[1:]) File "/usr/share/yum-cli/yummain.py", line 85, in main base.getOptionsConfig(args) File "/usr/share/yum-cli/cli.py", line 199, in getOptionsConfig errorlevel=opts.errorlevel) File "/usr/lib/python2.4/site-packages/yum/__init__.py", line 134, in doConfigSetup self.plugins.run('init') File "/usr/lib/python2.4/site-packages/yum/plugins.py", line 153, in run func(conduitcls(self, self.base, conf, **kwargs)) File "/usr/lib/yum-plugins/rhnplugin.py", line 109, in init_hook repo = RhnRepo(channel) File "/usr/lib/yum-plugins/rhnplugin.py", line 156, in __init__ url = channel['url'] + '/GET-REQ/' TypeError: can only concatenate list (not "str") to list Expected results: Should use the first listed server and work. If the first isn't available it should go to the second and try it ... Additional info: At some point in the past we went through this same issue with up2date. Same bug, new source.
Related to this bug is another. Perhaps it should be filed under rhnreg_ks?! After configuring the serverURL in /etc/sysconfig/rhn/up2date to allow for failover running rhnreg_ks clobbers it trashing all but the first item. It should leave it alone.
Oops, sorry about yet another email tonight. The rhnreg_ks issue appears to be the result of using --serverURL, so that is a self-inflicted wound. Ignore comment #1.
James, is this the right BZ component? Looks like yum-rhn-plugin?
Created attachment 155349 [details] patch to support failover urls The problem was actually that the plugin was not handling multiple channels. A side effect for adding multiple server URLS is that the channels are sent to the yum plugin as a list, the plugin was not handling lists correctly. Submitting to 5.1 and attaching patch.
fails_qa looks like this is not working added /etc/sysconfig/rhn/up2date serverURL=http://www.yahoo.com;https://xmlrpc.rhn.webqa.redhat.com/XMLRPC [root@rlx-3-10 ~]# yum update Loading "installonlyn" plugin Loading "rhnplugin" plugin There was an error communicating with RHN. RHN support will be disabled. Error communicating with server.
