There was a bug in the default algo, at least for VM hosting,
not that long ago. Not sure if it was fixed but I know we were
told here to use full instead, I'm guessing that's why he's using it too.

Because healing a VM disk without sharding freezes it for the duration of the heal,
possibly hours depending on the size. That's just not acceptable. Unless that's
related to the bug in the heal algo and it's been fixed ? Not sure
