Yes, see for example [this post](https://forums.foundationdb.org/t/shards-are-not-splitted-into-smaller-ones/815/9) which roughly describes the steps that occur when data is cleared from a process. The gist is that the actual clearing of key ranges doesn’t do much work initially but defers the cleanup to a background process.

Based on your status indicating that there is 0.0GB remaining (this number subtracts out the 5% minimum, but won’t go below 0), I think that suggests you have done so.

The number reported subtracts out the 5% floor, so 0.0GB means you have 5% or less space remaining.
