Re: [Linux-cluster] independent subtree



Hey there Lon,

May I ask you what exactly it is that provisioning _independent_subtrees does? Haven't seen it documented (and have read voraciously...).

A sincere thank you to you,

Dusty

Hello,
 when __independent_subtree is used and the resource fails the services is not
relocated after max_restarts. Is this a bug or is by design?

Example:

<service name="Web" domain="Web" autostart="1" max_restarts="2"
restart_expire_time="1800">
	<ip address="192.168.1.1" family="inet" monitor_link="1">
		<mysql name="Web_SQL" .../>
		<apache name="Web_Apache" __independent_subtree="1" .../>
	</ip>
</service>

the idea here is if MySQL have crashed mysqld_safe will restart it, but if
there is a problem with Apache - to restart it without stopping MySQL. This
works OK, but if there is a permanent problem with Apache (no access to the
file system) it is restarted several times without the service being relocated
to another node
    

By design.  There's a bugzilla open about adding per-resource restart
counters, it has not been implemented.
