--------------------------------------
Summary: upgrade from SizeTiered to Leveled failed because no
enough free space
Key: CASSANDRA-4556
URL: https://issues.apache.org/jira/browse/CASSANDRA-4556
Project: Cassandra
Issue Type: Improvement
Components: API
Affects Versions: 1.0.10
Environment: Cassandra 1.0.10, Ubuntu 64bit server.
Reporter: Cheng Zhang
I use cassandra 1.0.10 with two data directories and
SizeTieredCompactionStrategy first, after some time, the total free space is
smaller than the biggest data file. At this time, I want change the compaction
strategy to Leveled to save more space. But failed because there is no enough
space for the biggest data file to compact.
But when I change some code, if the biggest data file can't compact, I choose
the second biggest data file to compact, the rest can be done in the same
manner.The biggest data file will be compact when there is enough space. As the
compaction goes by, there will be enough space.
