Jonathan Ellis updated CASSANDRA-4467:
--------------------------------------
Priority: Minor (was: Major)
Affects Version/s: (was: 1.0.10)
1.0.0
Assignee: Yuki Morishita
Yuki, can you have a look at what would be required to make compaction able to
span multiple target directories?
My gut is that this is not a small change, in which case I'd rather mark it
Later since it's a pretty niche scenario.

> Key: CASSANDRA-4467
> URL: https://issues.apache.org/jira/browse/CASSANDRA-4467
> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Affects Versions: 1.0.0
> Environment: Ubuntu,Oracle Java 1.7,Cassandra 1.0.10
> Reporter: Cheng Zhang
> Assignee: Yuki Morishita
> Priority: Minor

> Cassandra has two data directories as follow:
> cassandra-disk0 use about 500G, about 250G free space
> cassandra-disk1 use about 500G, about 250G free space
> The max data file is about 400G. When I upgrade from
> SizeTieredCompactionStrategy to LeveledCompactionStrategy, there is no space
> to do this, for the free space of every data directory is small than the
> largest data file. But the total free space is enough for compaction.
