Hello everybody! I have 3 node cluster with replication factor of 3. each node has 800G disk and it used to have 100G of data. What is strange every time I run repair data takes almost 3 times more - 270G, then I run compaction and get 100G back. Unfortunately, yesterday I forget to compact and run repair again (at that moment I had around 270G). As result I have 720G on each node. I run compaction again and get a lot of warnings like this WARN [CompactionExecutor:732] 2012-09-26 16:13:00,745 CompactionTask.java (line 84) insufficient space to compact all requested files which makes sense, because I'm almost out of disk space. So, I have two questions. 1. Why repair almost triples data size? 2. How to compact my data back to 100G? Thank you, Andrey
