rhn_check -vvv ks errors

Sayli - changing a hostname is NOT supported on production Satellites. 

You keep the same hostname over upgrades. Backup all needed data to somewhere off server, reinstall OS on same hostname, restore/upgrade.

Please reproduce on a system where hostname was preserved.

Also - check rhn.conf for cobbler setting - it maybe currently set to 'localhost' this is incorrect. Set the Satellite server hostname within rhn.conf. 

Further - review your /etc/hosts file to make sure localhost and hostname are correctly configured. 

127.0.0.1 localhost
my-ip     servername

We need to confirm why 'localhost' - if it is due to normal upgrade and/or hostname/hosts issue or cos you renamed the Satellite's hostname during upgrade.

I am running into a similar problem sayli is seeing namely:

D: do_call kickstart.initiate ('localhost', 'spacewalk-koan', ' ksdevice=eth0 console=ttyS0,115200 ', '', 'sun-v20z-01.rhts.bos.redhat.com:1', [])

My Scenario is:

Sat 4.2.2 with External DB installed on RHEL4 i386.
Upgrade to Sat 5.3.0 RHEL4 s390x with External DB


My upgrade steps were (following scenario 1a)
1) Install sat 4.2.2 on external DB of rhnsat/rhnsat@rhnsat 
2) Install sat 530 on rhel4 s390x with a temporary external db jwmrhnsat10/rhnsat10/rhnsat10
3) Upgrade sat422 external db rhnsat to oracle 10g
4) Upgrade schema of sat422 on oracle 10g to sat530 schema, call this new db instance "jwmrhnsat"
5) Point my 530 install to new db instannce of "jwmrhnsat" which was the 4.2.2 sat with upgraded schema.


I did change hostnames, I went from hostname rlx-0-24.rhndev.redhat.com to rhndev1.z900.redhat.com.

I reproduced this as well
scenario
rhel4 5.11 to rhel4 5.3 no os upgrade. so no hostname change.
used the a profile that was created pre upgrade. will retest with a new profile.

rhncheck -vvv ks errors after upgrade

OK - during install we write:

 cobbler.host = rlx-1-18.rhndev.redhat.com

into the /etc/rhn/rhn.conf file - during the upgrade process though we will run various scripts to deploy/activate osad/push, Monitoring and misc other things, these scripts write/update config files within the /etc/sysconfig/rhn-satellite-prep/ and re-deploy. Because of this the rhn.conf file entry is lost (well backed up):


[root@rlx-3-08 rhn-satellite-prep]# grep -ir cobbler /etc/sysconfig/rhn/backup-2009-07-1*
/etc/sysconfig/rhn/backup-2009-07-13-12:48/etc/rhn/rhn.conf:cobbler.host = rlx-3-08.rhndev.redhat.com
[root@rlx-3-08 rhn-satellite-prep]# 


As such, we need to update the satellite cobbler installer to write an entry into the rhn-satellite-prep structure so that it is kept during upgrade OR add entry to upgrade steps to manually enter/add the config value :)

Cliff.

Should be fixed in the next release.. as of http://git.fedorahosted.org/git/?p=spacewalk.git;a=commit;h=9a04a11541e09092ee74322ab9b2a480ba6c8056

Verified on upgrade path: 

Sat 5.2.0 20081028.3 RHEL4 s390x external db -> Sat 5.3.0 RHEL4 s390x 

cobbler.host is correctly initialized after upgrade and system kickstart was successful.
