Public SourceMage Discussion List

[Jens Laas <jens.laas AT data.slu.se>]

I have made a SAN installation with sourcemage.

For this to work I needed the multipath-tools package and a custom initrd.

multipath-tools contains a daemon named multipathd that manages and 
creates device-mapper nodes under /dev/mapper.

These nodes are then used for mounting partitions.

Now the problem:

multipathd needs to be started before mountall.sh is run (and probably 
after devices and maybe even the whole of %DEV).

How do I configure this in the rc-script?

(It might suffice to run dmsetup and /sbin/multipath at an earlier stage).

Any help appreciated!

Thanks,
Jens

cat /etc/init.d/runlevels/%S/multipathd
#!/bin/sh

PROGRAM=/sbin/multipathd
RUNLEVEL=S
NEEDS=

. /etc/init.d/smgl_init

start() {
  echo -n "Starting multipathd..."
  /sbin/dmsetup mknodes
  /sbin/multipath
  $PROGRAM
}

stop() {
  echo -n "Stopping multipathd..."
  killall multipathd
}

reload() {
  $0 stop
  $1 start
}

restart() {
run_func reload
}
