for my raid boxes.... resyncing is all automated ... earn'd my fees that
way 

no manual recreation of the raid array ...
	- sometimes its a pain in the butt to get it working right
	so after using mdadm or other re-assemble the raid, one tends
	to leave it as is and merrrily proceed till the next failure

	- time vs $$$ vs frustration .. sometimes better to let it
	go ... make sure at least 2 independent redundant backups of the
	raid is working  and watch what happens

i assume that you have..
	- software raid1 
	- "FD" as your partition type
	- lilo.conf or grub or other pointing to the /dev/mdxx devices
	for booting
	- raid is built into the kernel .. not a module
	- /etc/raidtab setup up right

	- which version of raidtools are you using ??

- test regularly and often and randomly from bare metal
