0.91 is only used during a reshape - e.g. adding a device to a RAID5.
Once the reshape completes it will revert to 0.90.

You cannot upgrade the metadata on an array. You can only create a new array
with new metadata.
If you create a new array with current mdadm you will get v1.1 metadata.
If what you have works, there is no need to change it.
