So in a nutshell you're looking for a monitor application that will in
essence give you a green, yellow, or red light informing you of the
filesystem's health. Or some kind of SNMP logging that suggests a
corruption is imminent.
There is no such tool, and never will be. Nearly all XFS corruption
events are caused by either software bugs in the XFS code or elsewhere
in the Linux kernel, transient or permanent hardware failures, or power
failures, at some layer in the storage stack. It is not feasible to
predict such events.
When an XFS corruption occurs, one should report all related log
information and errors to this list so that the problem may be analyzed
and the root cause identified. Then the proper corrective action can be
identified and implemented to fix the problem and hopefully prevent it
