I just noticed that reducing the used dev size has not moved the metadata, so it is looking like it just isn't possible to shrink the md partition with metadata format 1.0?

From "man mdadm"

"The different sub-versions store the superblock at different locations on the device, either at the end (for 1.0), at the start (for 1.1) or 4K from the start (for 1.2)"

I don't really see how it could be shrunk with a superblock at the end, then you wouldn't be able to find it next time...
