+# Homework 2.4 Reclaiming disk space
+
+Note: MongoProc validation for this exercise requires that you are running MongoDB 2.6
+
+Over time a MongoDB database can become fragmented and cause reduced storage efficiency.
+
+In this problem we have provided you with an already fragmented database. You will want to extract the given handout and set mongod's dbpath to the appropriate folder.
+
+Your goal in this homework is to increase storage efficiency and reclaim disk space. You may use any method learned thus far to accomplish this goal. However, please do not tamper (remove/update/insert) with the database given apart from querying it to find out more information about the fragmented components.
+
+You are encouraged to use MongoProc to continuously test your progress until you are ready to grade the homework.
+
+Useful Formulas
+
+Collection Storage Efficiency:
+db.collection.stats().size/db.collection.stats().storageSize
+Database Storage Efficiency:
+(db.stats().dataSize + db.stats().indexSize) / db.stats().fileSize
+
+# Solution
+Database: fragDB
+Command: db.repairDatabase()
+- Before:
+db.fragColl.stats().size/db.fragColl.stats().storageSize
+0.14289938663772606
+(db.stats().dataSize + db.stats().indexSize) / db.stats().fileSize
+0.12821715218680246
+- After:
+0.8213309503784693
+0.45167418888636995
+
+# Example javascript to do the task and get info about fragmentation
+$ mongo fragDB task.js
+
+// Get a the current collection size.
+var storage = db.fragColl.storageSize();
+var total = db.fragColl.totalSize();
+
+print('Storage Size: ' + tojson(storage));
+
+print('TotalSize: ' + tojson(total));
+
+print('-----------------------');
+print('Running db.repairDatabase()');
+print('-----------------------');
+
+// Run repair
+db.repairDatabase()
+
+// Get new collection sizes.
+var storage_a = db.fragColl.storageSize();
+var total_a = db.fragColl.totalSize();
+
+print('Storage Size: ' + tojson(storage_a));
+print('TotalSize: ' + tojson(total_a));

 The writes that occurred before the backup will cause problems if replayed, because they will cause the database to deviate from the state it was in before the mongodump, so they need to be excised from the replay.
 The mongodump will be repeated when the oplog is replayed, potentially overwriting the original mongodump, so that operation needs to be removed from the oplog.
 The writes after the mongodump will need to be sorted, as they may not be in order.
-The db.collection.drop() command will still be in the oplog, and will need to be avoided.
-Ensure that any writes that occurred after the drop() command are not replayed (you might need to deal with these later), because these might lead to unexpected or inconsistent results.
