# Stops an ongoing resize operation on the pool.

`POST /pools/{poolId}/stopresize`

This does not restore the pool to its previous state before the resize operation: it only stops any further changes being made, and the pool maintains its current state. A resize operation need not be an explicit resize pool request; this API can also be used to halt the initial sizing of the pool when it is created.

## Path parameters
