I think we need to see what some of the more experienced users think
on this one.  But you can try removing sdh and seeing if you can mount
it *read only* and degraded.  Just make sure whatever you do and play
with is done read only.  Don't try any fixes or repairs with the tools
unless told to do so by someone who really knows what they're talking
about.
