What's the correct process for adding the failed /dev/sde1 back into the array so I can start it. I don't want to rush into this and make things worse.
There are a lot of discussions about this in the archives, but basically I recommend the following:
Make sure you're running the latest mdadm, right now it's 3.1.4. Compile it yourself if you have to. After that you stop the array and use --assemble --force to get the array up and running again with the drives you know are good (make sure you don't use the drives that was offlined a long time ago).
What's the correct process for replacing the 2 other drives? I am presuming that I need to --fail, then --remove then --add the drives (one at a time?), but I want to make sure.
Yes, when you have a working degraded array you just add them and a re-sync should happen and then everything should be ok if the resync succeeds.
