Are you sure you mean indenting rather than nesting?
Indentation is ignored in any XML structure. There is no difference in
meaning between:
<foo />
<bar />
and
<foo />
<bar />
But this would signify a dependency (bar depends on foo):
<foo>
<bar />
</foo>

Probably I was not completely correct in my assumptions.
The indenting configuration should assure that the inner resource is
started after the outer one. Is this true for rh el 4?
Instead, to have the behaviour regarding resource restatrt and not
whole service restart, in rh el 5.x you should write something like
this:
<fs ref="extstoragefs" __independent_subtree="1">
<script
ref="myscript"__independent_subtree="1" />
</fs>
<ip ref="10.4.5.6"/>
<script ref="mydb"/>
But this seems not to work in rh el 4. Is this supposed to work?
Thanks

Hello,
in RH EL 5.4 (and 5.5) it is possible to indent resources inside a
service definition (service = test_service), so that, having this:
<fs ref="extstoragefs">
<script ref="myscript"/>
</fs>
<ip ref="10.4.5.6"/>
<script ref="mydb"/>
Where resources are like these ones:
<resources>
<fs device="/dev/md0" force_fsck="0"
force_unmount="1" fsid="12263" fstype="ext3" mountpoint="/app"
name="extstoragefs" options="" self_fence="1"/>
<ip address="10.4.5.6" monitor_link="0"/>
<script file="/opt/myapp/init.d/myscript.sh"
name="myscript"/>
<script file="/etc/init.d/mysql" name="mydb"/>
</resources>
Suppose I have a failure in myscript app (I kill the app) I have a
restart in place of the resource itslef.
Instead it seems that in latest RHEL 4.8+updates I have a complet
service restart.
Is this the supposed behaviour so that there is different
functionality between RH EL 4.x and 5.x?
I suppose so, as I don't see any particular xml formatting
informations in cluster admin manual for rh el 4.x.... but I would
like to have a confirmation.
Any way to have similar parent-childs configuration in RH EL 4?
In logs, after kiil -9 of the process involved in myscript application I have:
