I'm using MongoDB 4.0.3 with WiredTiger engine in LXD container over ZFS filesystem.
> db.runCommand({compact: "fs.chunks"})
{ "ok" : 1 }
> db.stats()
{
"db" : "test",
"collections" : 3,
"views" : 0,
"objects" : 20633515,
"avgObjSize" : 8189.559693828221,
"dataSize" : 168979402786,
"storageSize" : 458719870976,
"numExtents" : 0,
"indexes" : 8,
"indexSize" : 3488063488,
"fsUsedSize" : 464063299584,
"fsTotalSize" : 578740813824,
"ok" : 1
}
> db.runCommand({compact: "fs.chunks"})
{ "ok" : 1 }

{
"db" : "test",
"collections" : 3,
"views" : 0,
"objects" : 20633519,
"avgObjSize" : 8189.558252617985,
"dataSize" : 168979405807,
"storageSize" : 458719866880,
"numExtents" : 0,
"indexes" : 8,
"indexSize" : 3488063488,
"fsUsedSize" : 464064217088,
"fsTotalSize" : 578740813824,
"ok" : 1
}
As you can see, DB didn't release unneeded space.
