NISHANT GUPTA commented on CASSANDRA-17215:
-------------------------------------------
I don't have logs for the period ({*}Dec 15 16:45).{*} Can't we debug the
snapshot issue based on this much data? As you said, snapshot simply creates
hard links to the directory, so why doesn't it contain the TOCfile? Is there
some logic based on time stamp of the files also?

> Key: CASSANDRA-17215
> URL: https://issues.apache.org/jira/browse/CASSANDRA-17215
> Project: Cassandra
> Issue Type: Bug
> Components: Tool/nodetool, Tool/sstable
> Reporter: NISHANT GUPTA
> Priority: Normal
>
> In apache cassandra 4.0, I am seeing that nodetool snapshot is not copying
> the TOC file for one of the sstable. The one difference with this sstable is
> that time stamp of the TOC file for the problematic sstable is 13 min past
> rest of the files.
