On my Centos system I installed kexec/kdump to investigate the cause of some random system-crashes by getting access to a crash-dump. I installed the rpm for kexec and then made the change to grub.conf that reserves the additional memory for the new kernel.
Also configured kdump.conf. I start the kexec service.and then I tried to simulate a crash by echo c to sysrq-trigger. The system does crash and then after a while reboots itself. But I see no vmcore when it coms back up. /var/crash is empty. This is when I tried to write to local drive. I also tried a nfs write but then still no success. Any idea what could be missing in my steps? Or any other debug suggestions? Any other kdump users on Beowulf? -- Rahul _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
