Hello,
The system is running a 4.18 (CentOS 8) kernel based on the CentOS 8.0 distribution.
I tested a dummy crash (echo h > /proc/sysrq-trigger) with both kexec-tools 2.0.19 and 2.0.20 packages.
The dump process seems to go to the end without complaining with following command:
/sbin/makedumpfile -D -d 0 -c --message-level 7 /proc/vmcore /tmpd/crashdump-${linux_ver}-${date_time}
I transfer the vmcore on a CentOS 8 machine running crash-7.2.9.
Following message appears during crash reading the core file:
crash: seek error: kernel virtual address: ffffffff8249c441 type: "memory section"
I'm a bit lost, because this mechanism was working on that type of hardware. What changed ? In the meanwhile, we switched from SysVinit to systemD. But I cannot imagine any impact.
Where should I look at ?
Thanks a lot.
Best regards,
Patrick Agrain
