This patch has to go elsewhere, to whoever maintains mkdumprd.

Many thanks for the plugin. I'll review it.

> Kdump check STONITH plugin "kdumpcheck"
> 1. Introduction
> This plugin's purpose is to avoid STONITH for a node which is doing kdump.
> It confirms whether the node is doing kdump or not when STONITH reset or
> off operation is executed.
> If the target node is doing kdump, this plugin considers that STONITH
> succeeded. If not, it considers that STONITH failed.
>
> NOTE: This plugin has no ability to shutdown or startup a node.
> So it has to be used with other STONITH plugin.
> Then, when this plugin failed, the next plugin which can kill a node
> is executed.
>
> 2. The way to check
> When STONITH reset or off is executed, kdumpcheck connects to the target
> node, and checks the size of /proc/vmcore.
> It judges that the target node is _not_ doing kdump when the size of
> /proc/vmcore on the node is zero, or the file doesn't exist.
> Then kdumpcheck returns "STONITH failed" to stonithd, and the next plugin
> is executed.
>
> 3. Expanding mkdumprd
> This plugin requires non-root user and ssh connection even on 2nd kernel.
> So, you need to apply mkdumprd_for_kdumpcheck.patch to /sbin/mkdumprd.
> This patch is tested with mkdumprd version 5.0.39.
> The patch adds the following functions:
> i) Start udevd with specified .rules files.
> ii) Bring the specified network interface up.
> iii) Start sshd.
> iv) Add the specified user to the 2nd kernel.
> The user is to check whether the node is doing kdump or not.
> v) Execute sync command after dumping.
>
> NOTE: i) to iv) expandings are only for the case that filesystem partition
> is specified as the location where the vmcore should be dumped.
>
> 4. Parameters
> kdumpcheck's parameters are the following.
