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 
healing completion?
