Hi Song, Thanks for your reply. Permissions were not set correctly on the directories so the longs were empty. I have corrected this and restarted apache. Service apache restart failed. It didn’t shut down apache correctly. Once I manually killed the process and restarted apache, the node began booting immediately.
In addition, I was advised by an apache admin to add “AcceptFilter http none” to my httpd.conf file. I have since done so and restarted apache. I will report back if it fixes the error. -Keith ____________________ Keith Hannum [email protected]<mailto:[email protected]> From: Song BJ Yang <[email protected]> Sent: Tuesday, January 22, 2019 10:30 PM To: [email protected] Cc: [email protected] Subject: EXTERNAL: 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<http://172.20.0.11/tftpboot/xcat/xnba/nodes/...>"? did it work if you restart apache/httpd? ------------------------------------------------------------------------------ YANG Song (杨嵩) IBM China System Technology Laboratory Tel: 86-10-82452903 Email: [email protected]<mailto:[email protected]> Address: Building 28, ZhongGuanCun Software Park, No.8, Dong Bei Wang West Road, Haidian District Beijing 100193, PRC 北京市海淀区东北旺西路8号中关村软件园28号楼 邮编: 100193 ----- Original message ----- From: "Hannum, Keith" <[email protected]<mailto:[email protected]>> To: xCAT Users Mailing list <[email protected]<mailto:[email protected]>> Cc: Subject: Re: [xcat-user] EXTERNAL: Re: xCat Diskless booting - http server doesn't respond Date: Tue, Jan 22, 2019 10:54 PM 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. https://stackoverflow.com/questions/21849794/apache2-runs-fine-for-a-while-then-stops-serving-content-error-when-restarting -Keith ____________________ Keith Hannum [email protected]<mailto:[email protected]> From: Mark Gurevich <[email protected]<mailto:[email protected]>> Sent: Tuesday, January 22, 2019 9:49 AM To: xCAT Users Mailing list <[email protected]<mailto:[email protected]>> Subject: EXTERNAL: Re: [xcat-user] xCat Diskless booting - http server doesn't respond 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 ?

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. _______________________________________________ xCAT-user mailing list [email protected]<mailto:[email protected]> https://lists.sourceforge.net/lists/listinfo/xcat-user _______________________________________________ xCAT-user mailing list [email protected]<mailto:[email protected]> https://lists.sourceforge.net/lists/listinfo/xcat-user
