Filesystem error logs

Anyone know
if / where / how
xfs filesystem errors / inconsistencies
are / can be
identified / logged / seen
at runtime / during normal system operation ?

(All xfs filesystem health monitoring options seem to require offlining and then actually applying fixes as opposed to just listing errors (according to xfs_repair man page))

Also of note: the default fstab values are for no fsck on boot.

There are a huge number of kprobes related to xfs, e.g. ‘kprobe:xfs_corruption_error’
