Created attachment 487187 [details] screen output of kdump fail to work Description of problem: Configure kdump location properly and then trigger system crash, it does not send vmcore file to remote nfs server or send incomplete vmcore file to ssh location. [root@localhost ~]# cat /etc/kdump.conf default reboot net 10.66.8.216:/var/crash [root@localhost ~]# service kdump status Kdump is operational [root@localhost ~]# echo c > /proc/sysrq-trigger Version-Release number of selected component (if applicable): rhev-hypervisor-6.1-10 How reproducible: Always. Steps to Reproduce: 1. setenforce 0 as bug 654565 exist. 2. configure kdump nfs or ssh location. 3. check kdump service is running # service kdump status Kdump is operational 3. make system crash: echo c > /proc/sysrq-trigger Actual results: it does not send vmcore file to remote nfs server or send incomplete vmcore file to ssh location. Expect Results: A complete vmcore file is generated at remote location. Additional info: 1. Attach screen output via serial console. 2. It is regression as it's not happened on 6.1-9, but ovirt-config-kdump file is the same.
That looks like a kdump regression, not RHEV-H specific, can it be reproduced with plain RHEL 6.1? Relevant package manifest diff 6.1-9 vs 6.1-10 is: -kernel-2.6.32-122.el6 +kernel-2.6.32-124.el6 -kexec-tools-2.0.0-169.el6 +kexec-tools-2.0.0-173.el6

It should be kexec-tools regression issue, test it on RHEL6.0 but with new kernel: kernel-2.6.32-125.el6 kdump work on kexec-tools-2.0.0-169.el6 kdump fail on kexec-tools-2.0.0-174.el6
Hmm, from your console log, I can't see any failure: Saving to remote location 10.66.8.216:/var/crash Free memory/Total memory (free %): 68400 / 115040 ( 59.4576 ) Excluding unnecessary pages md: stopping all md devices. : [100 %] kvm: exiting hardware virtualization sd 0:0:0:0: [sda] Synchronizing SCSI cache breth0: port 1(eth0) entering disabled state e1000e 0000:00:19.0: PCI INT A disabled Restarting system. machine restart BTW, does -172 work?
kexec-tools-2.0.0-172.el6 fail also.
Looks like a regression from -172. Could you try the latest -179? https://brewweb.devel.redhat.com/buildinfo?buildID=161029 Thanks.
work on kexec-tools-2.0.0-179.el6, it's succeed to generate vmcore file on local disk or remote disk.
