kdump with ssh (remote)

vmcore 를 ssh 를 통하여 원격지 서버에 전송하기 ( RHEL, CentOS)

  file : /etc/kdump.conf

ssh root@$(remote ip)

sshkey /root/.ssh/id_rsa

  # ssh-keygen -t rsa

# ssh-copy-id root@$(remote ip)

  아래와 같은 메시지가 발생됨.

/etc/kdump.conf

Rebuilding /boot/initramfs-3.10.0-229.11.1.el7.x86_64kdump.img

The specified dump target needs makedumpfile “-F” option.

mkdumprd: failed to make kdump initrd

  core_collector makedumpfile -F -l –message-level 1 -d 31

위와 같이 “-F” 옵션을 추가하면됨.
