Let's see:
1) rc.sysinit:
* remove swapon -a
* add
# Start up swapping.
/sbin/raidswapon &
after mount of /proc filesystem
* possibly comment out the "add raid devices" section; if you use raid
autostart chances are that the code in this section won't help you but it
WILL keep your system from comming up if there's anything bad in your
raidtab (happened to me when I did some testing and forgot to remove the
test - entries in raidtab).
my /sbin/raidswapon: (adapted from a post to this list - sorry, I don't
remember the original author).
#!/bin/sh
#
RAIDDEVS=`grep swap /etc/fstab | grep /dev/md|cut -f1|cut -d/ -f3`
for raiddev in $RAIDDEVS
do
# echo "testing $raiddev"
while grep $raiddev /proc/mdstat | grep -q "resync="
do
# echo "`date`: $raiddev resyncing" >> /var/log/raidswap-status
sleep 20
done
/sbin/swapon /dev/$raiddev
done
exit 0
This won't turn on swap on raid devices until resync has finished.
