Hi Paul,
rasters failing to load do not report any error to GeoServer, just a null.
This is a 10+ years old design mistake that's expensive to fix today (idea,
add a flag to make them throw an exception, retrofit each and every one of
them to do so).
As Daniele suggested, currently the way is to switch to gt Dev logging and
hunt into the many messages (some of which are red herrings).
The mosaic is especially hard because during init it creates tables, config
files and the like, won't revert them on failure, and won't proceed further
in the next setup if it finds them... So you have to know what to look for
and delete manually.
I hope one day we can setup a code Sprint with a few devs, for a few days,
to actually start returning meaningful info out if failures.
Cheers
Andrea
