Howdy, Running a round of updates from 6.3 to 6.4 and I'm seeing the following on all the servers. Want to make sure I'm not going to end up with a kernel panic if I reboot into the new kernel or have any other issues. Apr 22 11:10:21 www kdump: kexec: unloaded kdump kernel Apr 22 11:10:21 www kdump: stopped Apr 22 11:10:21 www kdump: mkdumprd: failed to make kdump initrd Apr 22 11:10:21 www kdump: failed to start up, config file incorrect I've never touched kdump.conf, or really used kdump at all.. /etc/kdump.conf shows: #raw /dev...

kdump operates by booting a fresh kernel to capture the context of a crashed kernel, and so the only way for kdump to dump a kernel is to crash it and cause kdump to invoke its post-crash kernel. You can manually force a running kernel to panic (and invoke a correctly-configured kdump) with the follo...

Hi, Is there a way to specify kernel version when (re)start kdump service? Suppose I have install a new kernel and kdump will generate kdump.img for new kernel in next boot. But I want kdump to generate kdump.img for new kernel immediately, is it possible? Thanks.

Hello, I am new in this mailing,please if somebody knows how to make kdump able to load in startup. i will be very thankful, -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.centos.org/pipermail/centos/attachments/20090409/d3435a68/attachment-0002.html>

However I'm unclear why anyone would want to remove kdump config in a sysprep operation. Or TCP wrappers for that matter. There seems to be no useful point in having virt-sysprep start to remove random config files. Rich. -- Richa...

Hi all, Here I am sending as attachments patches enabling kexec/kdump support in Xen PV domU. Only x84_64 architecture is supported. There is no support for i386 but some code could be easily reused. Here is a description of patches: - kexec-tools-2.0.3_20120522.patch: patch for kexec-tools which cleanly applies to version 2.0.3, - kexec-kernel-only_20120522....

Hi, This set of patches contains initial kexec/kdump implementation for Xen v2 (previous version were posted to few people by mistake; sorry for that). Currently only dom0 is supported, however, almost all infrustructure required for domU support is ready. Jan Beulich suggested to merge Xen x86 assembler code with baremetal x86 code. This could simp...
