I have a raid 5 built on an opensuse box that I just reinstalled Centos 
6.3 on.  Is it possible to rebuild the raid 5 array non-destructively?

I have googled on this and have found using mdadm --scan --assemble 
<list of fd devices>.  Will this do it?  I sure wouldn't want to lose my 
data on the array if possible.

thank you,
