Red Hat Bugzilla – Bug 604810
remove crashkernel=auto and use default syntax and move some decisions to user space
Last modified: 2013-09-29 22:17:00 EDT
Description of problem:
crashkernel=auto parameters seems to be doing too much. It also seems to be taking some policy decisions which are better taken in user space. One of such
decisions is that do not reserve any kdump memory on systems having less than
4G of ram. It might be better to move this policy decision in user space.
One possible place is some service in kexec-tools package and use /sys tunable "crash_kexec_size" to reduce the amount of memory reserved. May be by default we can reserve 128MB of memory and then shrink it by user space policy.
Version-Release number of selected component (if applicable):
This should be targeted for RHEL6.1
