Hmm. That seems to be saying that sstable2json is using the index file, and erroring out there the same way the Cassandra server does. So it doesn't necessarily mean the data files are corrupt. On Fri, Jun 11, 2010 at 11:20 AM, Lucas Di Pentima wrote: > Hello Jonathan, > > El 08/06/2010, a las 1

Sounds like you had some bad hardware take down your index files. (Cassandra fsyncs them after writing them and before renaming them to being live, so if it's missing pieces then it's always been hardware at fault that I have seen. You could try rebuilding your index files from the data files, but
