(Forget my last mail) Hi made some tests which succeed with all our operations (repair, add/remove nodes ...). The only thing I'm worrying about is that I met a situation where I had a lot of flushes on some nodes. You can find one of my system logs at http://pastebin.com/YZKUQLXz. I'm not sure as I didn't let it run for more than 4 minutes, but it seems that there was an infinite loop flushing system column families. A whole restart made this error go away but I'mn not sure if I can have this one come back.
