 941  941  Controls the checksum used to verify data integrity. The default value is
 942  942  \fBon\fR, which automatically selects an appropriate algorithm (currently,
 943  943  \fBfletcher4\fR, but this may change in future releases). The value \fBoff\fR
 944  944  disables integrity checking on user data. The value \fBnoparity\fR not only
 945  945  disables integrity but also disables maintaining parity for user data.  This
 946  946  setting is used internally by a dump device residing on a RAID-Z pool and should
 947  947  not be used by any other dataset. Disabling checksums is \fBNOT\fR a recommended
 948  948  practice.

      950 +The \fBsha512\fR, \fBskein\fR and \fBedonr\fR checksum algorithms require
      951 +enabling the appropriate features on the pool. Please see
      952 +\fBzpool-features(5)\fR for more information on these algorithms.
