* and the "sick" field tells us if that piece was found to need repairs.
* Therefore we can conclude that for a given sick flag value:
*
- * - checked && sick => metadata needs repair
- * - checked && !sick => metadata is ok
- * - !checked => has not been examined since mount
+ * - checked && sick => metadata needs repair
+ * - checked && !sick => metadata is ok
+ * - !checked && sick => errors have been observed during normal operation,
+ * but the metadata has not been checked thoroughly
+ * - !checked && !sick => has not been examined since mount
+ *
+ * Evidence of health problems can be sorted into three basic categories:
+ *
+ * a) Primary evidence, which signals that something is defective within the
+ * general grouping of metadata.
+ *
+ * b) Secondary evidence, which are side effects of primary problem but are
+ * not themselves problems. These can be forgotten when the primary
+ * health problems are addressed.
+ *
+ * c) Indirect evidence, which points to something being wrong in another
+ * group, but we had to release resources and this is all that's left of
+ * that state.
