Version 5 servers now use kexec with a kdump facility mechanism that will allow for remote dumping of the core. I'm not sure if netdump is functionally supported in your version of the kernel. Cheers, Date: Thu, 22 Jan 2009 16:23:19 -0500 From: srianirudh(a)gmail.com To: crash-utility(a)redhat.com Subject: [Crash-utility] netdump issue I am implementing a netdump . I crashed one sever and got the vmcore file in /var/crash/vmcore , then i checked the kernel version through strings vmcore | fgrep -m1 'Linux' Linux version 2.4.21-40.ELsmp (bhcompile(a)hs20-bc1-7.build.redhat.com) (gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-54)) #1 SMP Thu Feb 2 22:22:39 EST 2006 So now while installing the kernel-debuginfo , it should match the version above i.e something like "kernel-debuginfo.2.4.21.40.ELsmp.i368.rpm" But i installed the closest one and that was kernel-debuginfo.2.4.21.40.EL.i386.rpm but after installing them i should have /usr/lib/debug/module/vmlinux , which i could'nt see them . Can anyone give me the link to the rpm i am looking for , or suggest some idea. ( the server that i am dumping vmcore is version 5 ) I have bunch of server with version 2 and version 3 and version 4 in my production environment for which i have to configure netdump to collect the vmcore in version 5 server . -- Regards Anirudh Srinivasan _________________________________________________________________ Invite your mail contacts to join your friends list with Windows Live Spaces.
