Degraded ZFS with encryption

[Ruben Schade]

Hi all,

I've had a drive fail in a ZFS pool. The affected drive was 
automatically removed from the pool, and ZFS is reporting no known data 
errors. All good so far :)

  state: DEGRADED

Normally I'd just replace the physical drive and do `zpool replace`, but 
this is the first pool I’ve created using bsdinstall during the initial 
install process, and I elected for encryption.

Are there any further steps required to restore a drive in this 
configuration?

TBH this box was more for experimentation, I have full backups of the 
data in this pool. Just curious for future reference.

Cheers
