Description
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.
