In an extreme case, a drive could fail and a new one hot added while the
machine is live. Then reconstruction could occur while the swap area is
active. You might also like a cron job if you _REALLY_ want?

-Since swapping on a software raid is not save during the resync phase of

-swapon -a (md3 is my swap drive):
-
- #!/bin/sh
- #

- while /bin/grep md3 /proc/mdstat | /bin/grep -q "resync="
- do
- echo "md3 resyncing" >> /tmp/raidswap-status
- sleep 1
- done
- /sbin/swapon /dev/md3

-My setup is the following:
-
- /dev/md0 /boot raid1
- /dev/md1 / raid5 (3GB)
- /dev/md2 /home raid5 (30GB)
- /dev/md3 swap raid1
-
-Is the above script correct? What is the order that the raid code will
-reonstruct the different arrays? They are all on the same controller.
