-If at least one rotation occurred, only the tracing buffers and the current
-trace chunks are cleared. Previous trace chunks are not cleared.
+If a tracing session is configured in snapshot mode (see the
+nloption:--snapshot option of the man:lttng-create(1) command), the
+`clear` command only clears the tracing buffers.
+
+For a given tracing session, if at least one rotation occurred (see
+man:lttng-concepts(7)), the `clear` command only clears its tracing
+buffers and its current trace chunk, :not: its archived trace chunks.
+
+NOTE: The nloption:--disallow-clear option and the
+`LTTNG_RELAYD_DISALLOW_CLEAR` environment variable of
+man:lttng-relayd(8) can disable remote clearing operations. If LTTng
+sends tracing data over the network for the selected tracing session(s)
+to an LTTng relay daemon configured as such, the `clear` command fails.
