In case of disk full there is no expected behavior, we do not have tests
covering that case, nor I think the configuration subsystem is designed
to cope with such case.

Generally speaking, config wise, all we do is to write changes to
a temporary file, and then move the file over the previous one, using
an atomic rename on *nix systems, and a "delete and move" one
on Windows where atomic renames are not available.

Code here, if anyone as suggestions on how to make it better, it
would be appreciated:
https://github.com/geoserver/geoserver/blob/master/src/main/src/main/java/org/geoserver/data/util/IOUtils.java#L480

That said... as far as I know, we only change one file at a time,
and fail in case of IO error so... if you have many files corrupted, I may
be
that you had something that insisted on making changes on the configuration
despite the errors, and ended up ruining multiple files?

If the file contents is lost... it's lost.
For the service files (wms.xml and friends) you can find copies you
can restart from here:
https://github.com/geoserver/geoserver/tree/master/data/release

Hopefully those are the only you have ruined.

No guidelines here either, but a 0 length file is a good indicator
that the file is gone
