YOU WERE LUCKY !!! Use something like --assemble --force, which will set up a working array if it can. If that had been an old array, with a different offset or superblock or the like, you would have trashed the superblock and created a new array, which thought that the data in the array was somewhere other than where it really was. At which point, it would have been "go to your backups" or a major forensic recovery.
