and I think even this is too much. No point in triggering a monitoring
system in the middle of the night when the scrubs are running just
because of some bit rot on a disk. Losing a few bits on disks here and
there is a perfectly normal and expected scenario that Ceph can take
care of all by itself without triggering an health *error*. It
certainly doesn't require immediate attention (with auto repair
enabled) like the error state indicates.
The message in the cluster log should be enough.
