Zach Aller created CASSANDRA-7042: ------------------------------------- Summary: Disk space growth until restart Key: CASSANDRA-7042 URL: https://issues.apache.org/jira/browse/CASSANDRA-7042 Project: Cassandra Issue Type: Bug Environment: Ubuntu 12.04 Sun Java 7 Cassandra 2.0.6
Reporter: Zach Aller Priority: Critical Cassandra will constantly eat disk space not sure whats causing it the only thing that seems to fix it is a restart of cassandra this happens about every 3-5 hrs we will grow from about 350GB to 650GB with no end in site. Once we restart cassandra it usually all clears itself up and disks return to normal for a while then something triggers its and starts climbing again. Sometimes when we restart compactions pending skyrocket and if we restart a second time the compactions pending drop off back to a normal level. One other thing to note is the space is not free'd until cassandra starts back up and not when shutdown. I will get a clean log of before and after restarting next time it happens and post it. Here is a common ERROR in our logs that might be related ERROR [CompactionExecutor:46] 2014-04-15 09:12:51,040 CassandraDaemon.java (line 196) Exception in thread Thread[CompactionExecutor:46,1,main] java.lang.RuntimeException: java.io.FileNotFoundException: /local-project/cassandra_data/data/wxgrid/grid/wxgrid-grid-jb-468677-Data.db (No such file or directory) at org.apache.cassandra.io.util.ThrottledReader.open(ThrottledReader.java:53) at org.apache.cassandra.io.sstable.SSTableReader.openDataReader(SSTableReader.java:1355) at org.apache.cassandra.io.sstable.SSTableScanner.<init>(SSTableScanner.java:67) at org.apache.cassandra.io.sstable.SSTableReader.getScanner(SSTableReader.java:1161) at org.apache.cassandra.io.sstable.SSTableReader.getScanner(SSTableReader.java:1173) at org.apache.cassandra.db.compaction.LeveledCompactionStrategy.getScanners(LeveledCompactionStrategy.java:194) at org.apache.cassandra.db.compaction.AbstractCompactionStrategy.getScanners(AbstractCompactionStrategy.java:258) at org.apache.cassandra.db.compaction.CompactionTask.runWith(CompactionTask.java:126) at org.apache.cassandra.io.util.DiskAwareRunnable.runMayThrow(DiskAwareRunnable.java:48) at org.apache.cassandra.utils.WrappedRunnable.run(WrappedRunnable.java:28) at org.apache.cassandra.db.compaction.CompactionTask.executeInternal(CompactionTask.java:60) at org.apache.cassandra.db.compaction.AbstractCompactionTask.execute(AbstractCompactionTask.java:59) at org.apache.cassandra.db.compaction.CompactionManager$BackgroundCompactionTask.run(CompactionManager.java:197) at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Caused by: java.io.FileNotFoundException: /local-project/cassandra_data/data/wxgrid/grid/wxgrid-grid-jb-468677-Data.db (No such file or directory) at java.io.RandomAccessFile.open(Native Method) at java.io.RandomAccessFile.<init>(Unknown Source) at org.apache.cassandra.io.util.RandomAccessReader.<init>(RandomAccessReader.java:58) at org.apache.cassandra.io.util.ThrottledReader.<init>(ThrottledReader.java:35) at org.apache.cassandra.io.util.ThrottledReader.open(ThrottledReader.java:49) ... 17 more -- This message was sent by Atlassian JIRA (v6.2#6252)
