Re: [xcat-user] EXTERNAL: Re: xCat Diskless booting - http server doesn't respond

Hi Hannum,

 

did you observe any error in apache/httpd log,"access_log" and "error_log" under "/var/log/httpd/", on the server "172.20.0.11"? 

 

did it work if you restart apache/httpd?

The node successfully gets its IP from DHCP at bootup. I can wireshark to verify this but I don’t believe it is a DHCP issue. I tried 2 different nodes when in this state and both exhibit the same behavior (getting stuck trying to http get). I found someone with a similar issue with the web server, but unfortunately, no fix.

Could it be that DHCP lease for this node has expired after a few days ?

While this node is hanging, trying to get the image from the server, are you able to provision a different diskless node with the same OS image ?

I have xcat deployed on a CENTOS 6.8 node as my management node. The nodes were booting fine but some changes were made to the server. I don’t have the details of the changes but I am having an isse with xcat now. If the server is left running for a few days, if a diskless node is rebooted, it can no longer get its image from http. It hangs at getting the image forever with dots after the http get. i.e http://172.20.0.11/tftpboot/xcat/xnba/nodes/..... And the dots go on forever. If I reboot the management node, the diskless clients can immediately get their image, but after a few days, it stops working again. Httpd service is running. Not sure what to check for debug and was hoping for some direction to start troubleshooting. Thanks.
