Sorry for the late reply.

Those tools write a block, call fsync and send an UDP packet to another 
host or print it on a terminal. After a power cycle you compare what you 
have and what you should have. One of those tools is:

I agree that this message is catastrophic from a user friendly point of 
view. Before you got that message there must have been another line in 
dmesg from the time you mounted the FS.

What XFS likes to tell you is:

My meta data got corrupted, most probably due to a hardware failure, you 
need to run xfs_repair _ASAP_ on that FS. I will however continue in 
trying to mount the requested FS to give you a chance to backup your 
data or get your system back online. If however I encounter any 
suspicious position I will immediately shutdown to FS to prevent any 
further damage. This is my last cry to run xfs_repair on me.

Best regards,
