Hi,
I installed the UEC including MANAGED-NOVLAN mode with "http://cssoss.files.wordpress.com/2010/06/book_eucalyptus_beginners_guide_uec_edition1.pdf"
this manual.
After I setup client1, I excute this "euca-describe-availability-zones" but it doesn`t work. I check connection between server1(installed CLC, CC, SC, walrus) and server2(installed NC). They can communicate each other.
All UEC components execute their position(using "status eucalyptus-XX")
/var/log/eucalyptus/httpd-cc_error_log
and I found this error message,
[Wed Aug 04 18:48:45 2010] [error] server is within MinSpareThreads of MaxClients, consider raising the MaxClients setting
I want to know this log message`s meaning. Is it related this problem?
how can I make connection between CC and NC?
Thank you for your support.
Sometimes the nc process does not start at startup.
Do a ps -auxwwf| grep euca and see if the nc process is running. try to start or restart the same by
/etc/init.d/eucalyptus-nc restart
sudo restart eucalyptus-nc
then try running euca-describe-availability-zones verbose
Hello,
You can ignore that error log in "httpd-cc_error_log". Try find "nc.log" and see if the log file contains any message.
If the file is not created, that means communication never took place between CC and NC.
Then try parsing "cloud-debug.log" to see there's any message that's relevant to it. One of the likely problem is in credential propagation step ($EUCALYPTUS/usr/sbin/euca_conf --register-cluster or $EUCALYPTUS/usr/sbin/euca_conf --register-node). If you registered with host name of CC/NC, try registration with IP address.
