I presume that you actually mean that you created an array ontop of the
disks from another array.
so I lost my array and my data.

Well, if you used the same metadata version (like 1.2 for instance), the
"old" metadata would have been overwritten by your new RAID metadata
(assuming you built the RAID on the same drives/partitions) so that
would be gone as well.
Even if you were able to rebuild the "previous" RAID (also assuming it
was a RAID5), if your current RAID build has completed the data would
have been thoroughly destroyed by the build process and recovery would
be insanely hard.
