When receiving the following error...

{"jsonrpc":"2.0","error":{"code":-32000,"message":"all subnets' staking period must be a subset of the primary network","data":null},"id":1}

It means that a node cannot be a validator on a subnet longer than it is a validator on the Primary Network. For example, if the node has only three weeks left in its current validating period, it cannot start a validation on a subnet that is 30 days long, it can only be 21 days or less.

The remaining validation time can be seen in the explorer if you look up the validation transaction, or on https://avascan.info/ or similar services.
