I use a RAIDframe RAID 1 mirror on my NetBSD/alpha system. There, they
have a "swapoff" rc.conf variable that you should set to "YES" to have
block swap devices removed (via "swapctl -U -t blk") during the rc.d
shutdown sequence.
Before that was introduced, I found that my /dev/raid1b swap device
would initiate a parity rebuild upon reboot (presumably because it
hadn't quiesced prior to shutdown).
What does geom_mirror do with respect to quiescing prior to shutdown?
Cheers,
Paul.
