[SSI-users] Loadleveling scripts

[Javier C. <jc...@un...>]

Hi all

I'm in the following situation: I want some of my scripts loadleveled,
so I have /bin/bash in the loadlevellist. But I don't want the scripts
in /etc/init.d to be loadleveled when I (re)start a service with
invoke-rc.d (I use Debian). I want them to execute in their own node.=20

For example, when I boot the cluster inetd is started once in each node.
That's ok, as loadleveling is not on yet. Now, if I do a invoke-rc.d
inetd restart, the invoke-rc.d script creates a bash process for each
node to execute the script /etc/init.d/inetd. As they are launched with
the command onclass, those bash processes run in a different node each
one; BUT bash appears in the loadlevellist, so the command inetd
executed from those processes can be rexec'ed to another node, by the
inherited loadlevel property. In my two node cluster I end up with two
inetd processes running in node 2, because it is less loaded than node
1.

I've seen that, as well as the loadlevel property, the pin property is
inherited from the parent process too. This way I think that pinning the
bash processes that launch the real services to the node they are
executing in would solve this problem. But the command onclass has no -p
option...

Is there another solution to this? Is it planned to include that option
to the onclass command?

BTW, what happens to the pin and loadlevel properties of a process whose
parent dies and gets adopted by init?

Thank you all
