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'.
