Ariel Weisberg commented on CASSANDRA-9347:
-------------------------------------------

I think you have to do option #2 right now. It's not designed to run 
indefinitely because it doesn't discard log segments as it goes. That is 
something I would like to fix. Maybe also look into exercising commit log 
archiving as well? 

I am still on the fence as to whether this is the right way to test this 
subsystem, but we made changes for 2.2 so we should do what we can now.

> Commitlog stress runs each test for 10 seconds based on a constant. Might be 
> worth raising that to get the CL doing a little bit more work.
> Then run it in a loop on something with a fast SSD and something with a slow 
> disk for a few days and see if it fails.
