## 12.8.4 Encrypted MDisks 

For instructions about how to add external storage to a pool, see Chapter 6, “Storage pools” on page 213. Each MDisk that belongs to external storage and is added to an encrypted pool or child pool is automatically encrypted by using the pool or child pool key, unless the MDisk is detected or declared as self-encrypting. 

The user interface has no method to see which extents contain encrypted data and which do not. However, if a volume is created in a correctly configured encrypted pool, then all data that is written to this volume will be encrypted.
