sh : URGENT synchronisation insmod in script
Hello,
By now in linux 2.4, I have a sh script wich start 2 modules as follow :
/sbin/insmod module1.o
/sbin/insmod module2.o
I added an application in user space named "user_app" which communicate with module1 with a /proc.
I now tape the commands myself during code execution on a shell console :
>>/sbin/insmod module1.o &
>>./user_app
then when module1 insmod IS COMPLETED I do :
>>/sbin/insmod module2.o
I now would like to wright this in the start sh script , how should I wright this (background user_app launch and "wait for the end of module1 insmod ") ?
Many thanks for your help,
Celine

volinstall
volinstall(8) System Manager's Manual volinstall(8)
NAME
volinstall - Sets up Logical Storage Manager (LSM) environment after LSM installation
SYNOPSIS
/usr/sbin/volinstall
DESCRIPTION
The volinstall script sets up LSM special device files, and add the following lines to the /etc/inittab file:
lsmr:s:sysinit:/sbin/lsmbstartup -b </dev/console >/dev/console 2>&1 lsm:23:wait:/sbin/lsmbstartup -n </dev/console >/dev/console 2>&1
vol:23:wait:/sbin/volreconfig -n </dev/console >/dev/console 2>&1
The first line calls the /sbin/lsmbstartup script, which enables LSM to start automatically on system reboot. The second line calls the
/sbin/volreconfig script, which handles any pending encapsulation requests.
If /sbin/lsmbstartup is not added to the /etc/inittab file, LSM must be started manually after system reboot.
Note
The volinstall script is automatically invoked by the volsetup, clu_create, and clu_add_member commands. Therefore, running the volinstall
script to set up LSM is usually not necessary.
