Hello,
Before I ask my question - if there is some documentation that answers
what I am asking - I would be thrilled to read it. So far google has not
helped me at all.
This being said I need help with understanding what is going on here

Afterwards I removed sde from all arrays and mounts, and grilled it
repeatedly with badblocks and smartctl -t long. Nothing came out for
over a day. Below see the smartclt -a output. This happened one day
after I upgraded to 2.6.27.4 from 2.6.23.
Can someone please tell me what seems to be dying? Thank you!
