zfs discuss - Sep 2010 - Proper procedure when device names have changed

I am running zfs-fuse on an Ubuntu 10.04 box.  I have a dual mirrored pool:
mirror sdd sde mirror sdf sdg

Recently the device names shifted on my box and the devices are now sdc sdd sde
and sdf.  The pool is of course very unhappy about the mirrors are no longer
matched up and one device is "missing".  What is the proper procedure
to deal with this?

Or you can go into udev''s persistent rules and set it up such that the 
drives always get the correct names. I''d guess you''ll probably
find them
somewhere under /etc/udev/rules.d or something similar. It will likely 
save you trouble in the long run, as they likely are getting shuffled 
with either a kernel or udev upgrade.

That seems to have done the trick.  I was worried because in the past
I''ve had problems importing faulted file systems.
