Hi Ken,

You run e2fsck on the partition. So if your raid is sdb and sda then 
your raid device is /dev/md127 or /dev/kensarray/bigdisk or something 
like that. Then your partition is on top of that.


Hopefully you have your partition mounted on /mnt/allmydata for example 
and you just umount it and run e2fsck on whatever the block device is.


If you have boot and root on raid, I would boot with a recovery USB 
like  sysrescue and then run the tests offline. It should assemble your 
raid automatically to save stuffing around as well.


Also make sure you are using the right filesystem checker, I have just 
assumed you are using ext4
