With 3.3.1, healing happens in two modes:
a) index heal - based on changes recorded in indices on bricks. The
indices are consumed by self-heal daemons on each server for performing
healing and is the default mode of operation.
b) full heal - works through a full crawl of the volume. In this mode,
self-heal daemon inspects changelogs of all files and directories it
encounters during a crawl. This mode is triggered when volume heal full
command is used.
Normally, a) is faster and addresses most healing cases. Do you have
more details on files that require a full heal to be performed for
