[lug] sw raid resynch

[dio2002 at indra.com]

i just finished the initial install on my system using sw md raid 1.

currently md is resyncing the mirror drive in the array.  it's late and i
want to power down and let it finish in the morning.

i've heard it's dangerous to shutdown in the middle of the resynch.

Is that really true and if it is, would it be an "unrecoverable dangerous"
or simply that i'd need to resynch from scratch next time i reboot off of
the good drive?

Finally, is it possible to use mdadm commands to pause a resynch so that
you can safely shutdown and then restart it upon reboot or does it need to
finish per above?

fyi, i am letting this resynch run to completion.  just asking. :-)
