Presumably, yes.
If you provide "mdadm --examine" from devices in both the "working" and
the "not working" case, I might be able to point to the difference.
Alternately, use "mdadm --dump" to extract the metadata, then "tar
--sparse" to combine the (sparse) metadata files into a tar-archive, and
send that. Then I would be able to experiment myself.
