Illarion Kovalchuk created CASSANDRA-5308:
---------------------------------------------
Summary: cassandra with leveled comaction quickly runs out of free
space with tons of tmp files
Key: CASSANDRA-5308
URL: https://issues.apache.org/jira/browse/CASSANDRA-5308
Project: Cassandra
Issue Type: Bug
Components: Core
Affects Versions: 1.1.10, 1.1.9
Environment: Cluster with 4 nodes running cassandra 1.1.10
Reporter: Illarion Kovalchuk
Fix For: 1.1.11
We were performing a massive upload of data to our cluster and found, that one
of the nodes is ruuning out of free space
nodetool ring didn't show any extra usage, but df -h / on the problamatic node
shown us 95% of used space, while other nodes were all around 50%
Eventually, we discovered that there's an abnormous peak of tmp files in one of
our CF's: 753'906'319'257 bytes of data in 26811 files.
Rebooting the node caused all that files to get deleted and node went back to
normal.
One of the symptoms: when the node started to misbehave and collect the temp
files, it started to flush the memtables due to lot of heap used.
