Under normal conditions, if you write 1 byte to a file, only 1 byte is
written to all servers. But, if during writing 1 byte, one of the servers
was down, then 1 byte is written to the reamining server(s). when the server
which was down comes back up, and the file is accessed again, then the
entire file content from the updated server is copied to the lagged server
(this is the self-heal process). We are working on improving the healing
efficiency for such situations (minor changes on large files)
