Subject Re: Argh: Data Corruption (LOST DATA) (0.7.0)
Date Sat, 05 Mar 2011 10:47:17 GMT
Also, if you can, please be sure to try the new 0.7.3 release. We had a bug
with the compaction of superColumns for instance that is fixed there (
https://issues.apache.org/jira/browse/CASSANDRA-2104). It also ships with a
new scrub command that tries to find if your sstables are corrupted and
repair them in that event. I can be worth trying it too.
