Description

$ lttng snapshot record -m 16384
Error: Snapshot record failed

The real reason is apparently that the size is too small, but that is not clear from the error message. An indication of what the minimum size is would be useful. Displaying it in a symbolic way ("Minimum size is NR_CPU * SUBBUF_SIZE * WHATEVER") would be nice, but displaying the minimum value for this particular session would be nicer ("Minimum size is 123456 bytes").
