Description
When a ZFS volume is created with zfs create -V (but without -s), the refreservation property is set to a value that is volsize plus the maximum size of metadata. If refreservation is ever set to another value, it is impossible to set it back to the automatically determined value. There are other cases where refreservation may be wrong. These include receiving a volume that was sent without properties and zfs clone.
We need:
zfs set refreservation=auto <volume> zfs clone -o refreservation=auto <volume>
Each one would use the same function used by zfs create -V to determine the proper value for refreservation.
