Ivo Meißner commented on CASSANDRA-4481:
----------------------------------------
I am still trying to narrow it down. I have created a new keyspace
("testkeyspace") with the same configuration and structure.
When I only use the testkeyspace, the error does not occur, everything in the
commitlog is available after reboot:
The following works as expected:
1. Insert dataA in testkeyspace
2. Reboot -> 1 replayed mutations
3. Get dataA returns data as expected
The following does not work:
1. Insert dataA in testkeyspace
2. Get dataA from testkeyspace -> returns data as expected
3. Insert dataB in brokenkeyspace
4. Get dataB from brokenkeypsace -> returns data as expected
5. Reboot -> 0 replayed mutations
6. Get dataA from testkeyspace -> NO DATA
7. Get dataB from brokenkeyspace -> NO DATA
So it seems to have something to do with the "broken" keyspace. I don't know
yet how to get the keyspace into that state. So any input of how I can figure
it out or what I could try would be appreciated.
I have changed the Fix-Version to 1.1.4.

>
> When data is written to the commitlog and I restart the machine, all commited
> data is lost that has not been flushed to disk.
> In the startup logs it says that it replays the commitlog successfully, but
> the data is not available then.
> When I open the commitlog file in an editor I can see the added data, but
> after the restart it cannot be fetched from cassandra.
