The file system is using twofish-cbc-essiv:sha256, apparently. (I
went and dug up a mothballed machine of mine because of your post).
And I agree, encrypting everything is a good practice— I once got a
disk back from RMA where only the first sectors were zeroed and the
rest had someone elses data, since then I've encrypted everything
because you can't wipe a dead drive.
I'd love to know precisely what Bitcoin is doing thats making your
machine so unhappy... but your configuration is uncommon for bitcoin
nodes in many distinct ways so it's not clear where to start.
