I have a mongod node which is using much more disk space than stored object space. On Wednesday, I --repair'd the database, which brought the storageSize down to ~dataSize, now storageSize is back to 44x the dataSize!
In this case, dataSize is ~480Mb, storageSize is ~21Gb, and there are ~24Gb of database files.
> db.stats() { "db" : "dbname", "collections" : 8, "objects" : 4729, "avgObjSize" : 101896.2233030239, "dataSize" : 481867240, "storageSize" : 21079039904, "numExtents" : 39, "indexes" : 11, "indexSize" : 1332688, "fileSize" : 25204097024, "nsSizeMB" : 16, "ok" : 1 }
I'll attach some python code that reproduces the problem.
