+.SH "DESCRIPTION"
+The \fBzdb\fR utility displays information about a ZFS pool useful for
+debugging and performs some amount of consistency checking. It is a not a
+general purpose tool and options (and facilities) may change. This is neither
+a fsck(8) nor an fsdb(8) utility.
+
+.P
+The output of this command in general reflects the on-disk structure of a ZFS
+pool, and is inherently unstable. The precise output of most invocations is
+not documented, a knowledge of ZFS internals is assumed.
+
+.P
+When operating on an imported and active pool it is possible, though unlikely,
+that zdb may interpret inconsistent pool data and behave erratically.
+
+.SH "OPTIONS"
