Hi,

I have cluster of three Cassandra (v.2.1) machines. On one of the machines files with commit logs filled up all available disk space (50 GB).

I haven't change 'commitlog_total_space_in_mb', so as far as I know It shouldn't take more that 8GB of disc space.

I also haven't found any suspicious messages in log file and our cluster was not hammered by huge amount of requests lately.

This machine (cassandra process) is not able to boot up now (it crashes while replaying commit_log)


1. How can I find out what happened?

2. Can I just delete all commit_logs, restart machine and run repair to have consistent data?

3. Maybe I can delete just part of the commit_log files so Cassandra will be able to boot and clean (flush) all commit_log files?


Regards,

Pawel
