Hello,
your problem is of course that the weight is 0 for all your OSDs.
Thus no data can be placed anywhere at all.
You will want to re-read the manual deployment documentation or dissect
ceph-deploy/ceph-disk more.
Your script misses the crush add bit of that process:
ceph osd crush add {id-or-name} {weight} [{bucket-type}={bucket-name} ...]
like
"ceph osd crush add osd.0 1 host=host01"
