Hi all,

I managed to get my RAID drive back up, content looks like it's still
there, but it's not resyncing or reshaping and my parity drive was
removed (I did it when I tried to get it back up).

If you can see your content (mounted read-only, I hope), backup up
everything, in order from most critical to least critical.

So what should I do now? I'm afraid of doing anything else at this point.

Well, you need to provide more information.  At least the mdadm -E
reports for all of the member devices.  Including the "parity" device
you removed.  (Parity is spread among all devices in a normal raid5
layout, so you may be suffering from a misunderstanding.)

Phil,
   Please reference the thread entitled

"Raid 5 array down/missing - went through wiki steps"

All the mdadm -E info and much more was reported there a week
ago. Wols and I helped get him that far but neither of us was confident
in giving instructions to get him further.

Cheers,
Mark
