Hi,

I found something rule like this;
When the following process was killed, the system would reboot.
* ccm
* cib
* lrmd
* crmd
* pengine
* tengine

These processes would be restarted when they are killed.
* FIFO
* media (ex. write/read bcast)
* stonithd
* attrd
* mgmtd
* respawn (ex. pingd)

If mcp is killed, Heartbeat2 is going to stop.
(but, lrmd and mgmtd might remain...)

MCP getting a TERM signal means exactly that.

Is there any policy what process is desired, restart itself or reboot the
system?

Yes, but it's hardcoded.

I think it wouldn't be hurt if the death of all process raise a reboot.
It's simple.

Yes, but not necessary. I believe that reboot is done only for
those processes for which recovery is too difficult to be done
properly.

actually i'd much prefer if none of the crm processes caused a reboot
but my opinion didnt matter



Thanks,

Dejan

by the way, changeset is f153a9be0bdf.
