Subject Disk Full Error on Cleanup
Date Fri, 26 Nov 2010 15:18:21 GMT

I keep running into the following error while running a nodetool cleanup:

ERROR [COMPACTION-POOL:1] 2010-11-26 12:36:38,383
(line 87) Uncaught exception in thread
java.lang.UnsupportedOperationException: disk full
        at org.apache.cassandra.db.CompactionManager.doAntiCompaction(
        at org.apache.cassandra.db.CompactionManager.doCleanupCompaction(
        at org.apache.cassandra.db.CompactionManager.access$400(
        at org.apache.cassandra.db.CompactionManager$

        at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(
        at java.util.concurrent.ThreadPoolExecutor$

There is 80GB used out of a 150GB partition that is dedicated to the
cassandra data partition.  So, this seems to related to another issue
around a disk that doesn't have enough space for the anit-compaction.
This keep nodetool cleanup from completing since this occurs at the
beginning of the run.

I also tired running compact on this node and then cleanup but the
same error results.

Any ideas or pointers?
