Well, that means nothing thinks it's not working.  Not an encouraging
sign :/

Hrm.  If you run "dmsetup table" from this environment, does the output
match the "dm create" line in the initrd?

It's almost as if lvm isn't checking the dm volumes, but that shouldn't
be the case with even remotely recent lvm2.

This could be related, but my gut reaction says it's not caused by your
raid problems.  Obviously it's still bad.
