  Hi Ping Tian Han, 

  Like mentioned in the bug description, I see there is no option for
  dumping through network in /etc/default/kdump-tools,

  Can you try manually adding NFS"<nfs location to dump vmcore>" in the
  /etc/default.kdump-tools and check if this fails to dump vmcore or
  successful ?

  Thank you.

  I added NFS="10.33.4.4:/distros" in the file then run "service kdump-
  tools restart", then triggered kdump, but it doesn't try the NFS
  location, still dump to local disk.

  After adding the NFS details in /etc/default/kdump-tools and restarting the kdump service, there is no NFS details while doing a 'kdump-config show'.

  root@pinelp2:~# kdump-config show
  USE_KDUMP:        1
  KDUMP_SYSCTL:     kernel.panic_on_oops=1
  KDUMP_COREDIR:    /var/crash
  crashkernel addr: 
  current state:    ready to kdump

  kexec command:
    /sbin/kexec -p --args-linux --command-line="BOOT_IMAGE=/boot/vmlinux-3.19.0-22-generic root=UUID=8846b7fd-86b3-4823-a985-b57c279d1856 ro irqpoll maxcpus=1 nousb" --initrd=/boot/initrd.img-3.19.0-22-generic /boot/vmlinux-3.19.0-22-generic
