If this is a part of an active RAID then this should not be an
issue.  If this signature is really spurious then it should not be
there and I do not think that anything will be lost although I
cannot tell for sure in all situations.  I am not that familiar with
details of such setups.  In any case, if this is _really_ what you
are looking at, then 'dmraid -E -r ...' makes a backup, in root
$HOME AFAICT, of metadata removed.

Proceed with caution but I, for one, am quite interest in what
you will find.
